E-FILED Monday, 23 January, 2012 11:20:09 AM Clerk, U.S. District Court, ILCD UNITED STATES DISTRICT COURT CENTRAL DISTRICT OF ILLINOIS URBANA DIVISION ______________________________________________________________________________ RONALD CAPPELLANO, Plaintiff, v. WRIGHT MEDICAL GROUP, INC.,a corporation, WRIGHT MEDICAL TECHNOLOGY, INC., a corporation, and WRIGHT MEDICAL EUROPE SA, a corporation, Defendants. ) ) ) ) ) ) ) ) ) ) ) ) Case No. 08-CV-2265 OPINION This case is before the court for ruling on the Combined Motion to Dismiss and Motion for Summary Judgment (#90) filed by Defendants, Wright Medical Group, Inc., Wright Medical Technology, Inc. and Wright Medical Europe SA. This court has carefully reviewed the arguments of the parties and the documents filed by the parties. Following this careful and thorough review, Defendants Combined Motion to Dismiss and Motion for Summary Judgment (#90) is GRANTED in part and DENIED as moot in part. FACTS1 Plaintiff, Ronald Cappellano, underwent hip replacement surgery on October 14, 2004. Plaintiff had been diagnosed with degenerative joint disease of the left hip. Plaintiff s doctor placed a Profemur® prosthesis, model PHA0-1244, long neck, 15 Degree A/R Long, 1 The facts are taken from Defendants statement of undisputed facts, Plaintiff s statement of additional undisputed facts and the documents submitted by the parties. This court has only included facts which are adequately supported by evidence in the record. in Plaintiff s left hip. This prosthesis was a modular prosthesis which was manufactured by Defendants. The modular prosthesis consists of separate components and is promoted as providing the surgeon with greater flexibility. The neck of the modular prosthesis was made of titanium alloy. The report from the October 14, 2004, surgery stated that [v]arious combinations of neck length and version were used to obtain the most stable construct. It is undisputed that prostheses with a monolithic design, consisting of only one part, were available as an alternative to Plaintiff s doctor, Dr. Paul F. Plattner, who chose to use the Profemur® modular implant instead. At the time of the surgery, Plaintiff was 62 years old, was 6 feet tall and weighed 276 pounds. A clinical consultation report dated October 8, 2004, stated that Plaintiff was overweight by probably 90 pounds. The prosthesis package insert, which was available to Plaintiff s doctor, stated that it must be recognized that [hip replacement prostheses] are made from metal, ceramic, and plastic materials and that any hip replacement system, therefore, cannot be expected to withstand activity levels and loads as would normal healthy bone. The insert also stated that the system will not be as strong, reliable, or durable as a natural human hip joint. The insert listed the patient s weight as a factor which could be critical to the eventual success of the procedure and explained that [a]n overweight or obese patient can produce high loads on the prosthesis, which can lead to failure of the prosthesis. The insert stated that the procedure was absolutely contraindicated by obesity where obesity is defined as three times normal body weight. The insert also stated that the patient should be warned that the prosthesis does not replace normal healthy bone, that the prosthesis can 2 break or become damaged as a result of certain activity or trauma, has a finite expected service life, and may need to be replaced at some time in the future. Plaintiff signed a consent for the procedure the day of the surgery. The consent form was also signed by Plaintiff s doctor. By signing the form, Plaintiff s doctor stated that he had given Plaintiff an adequate and appropriate explanation of the nature and purpose of all the treatment and procedure(s) consented to above, possible alternative methods of treatment or procedures, the expected risks and benefits involved and the possibility of complications in the treatment and/or procedure(s) consented to and in alternative treatments or procedures. Plaintiff stated that I understand the nature of the proposed procedure(s), attendant risks involved, and expected results as described above, and hereby request such procedure(s) be performed. On or about March 21, 2008, the neck of the prosthesis which had been implanted in Plaintiff s left hip failed. Plaintiff underwent revision surgery on March 25, 2008, and the prosthesis was removed. During the time the hip prosthesis was in place, Plaintiff weighed between 260 and 290 pounds. Plaintiff weighed 260 pounds at the time of the revision surgery and the report from the surgery stated that the fact that he was 260 pounds and obese greatly complicated the case. The report also stated that the cause of the failure of the prosthesis was acute fracture of the neck. Plaintiff s deposition was taken on August 15, 2011. Plaintiff testified that his doctor told him that hip prostheses lasted, on average, around 20 years. PROCEDURAL HISTORY 3 Plaintiff filed a Complaint against Defendants in the Circuit Court of Champaign County on October 8, 2008. Plaintiff alleged that the prosthesis system manufactured by Defendants was unreasonably dangerous for its intended or reasonably foreseeable uses. On November 4, 2008, Defendants filed a Notice of Removal (#1) and removed the case to this court based upon diversity jurisdiction. On January 20, 2009, a Discovery Order (#12) was entered which set a deadline for the amendment of pleadings of August 1, 2009. The Discovery Order also set the case for a jury trial on June 28, 2010. Unfortunately, problems with discovery have prolonged this case well beyond the original trial date. The discovery order was amended many times and the jury trial has been rescheduled numerous times. On June 10, 2011, Plaintiff was allowed to file his First Amended Complaint (#82). Plaintiff alleged that Defendants designed, manufactured, distributed and sold the hip prosthesis system in question. Plaintiff again alleged that the prosthesis system was unreasonably dangerous for its intended or reasonably foreseeable uses. Plaintiff focused his allegations on problems with the neck portion of the prosthesis and alleged that the prosthesis was unreasonably dangerous under the risk-benefit test and that the prosthesis system in question was dangerous to an extent beyond that which would be contemplated by the ordinary consumer with the ordinary knowledge common to the community as to its characteristics. On July 29, 2011, the jury trial was rescheduled once again and is currently scheduled for March 5, 2012, at 9:00 a.m. On October 3, 2011, Defendants filed their Combined Motion to Dismiss and Motion for Summary Judgment (#90), with an attached Memorandum in Support and Exhibits. 4 Defendants also filed some of their supporting Exhibits (#91) under seal. On October 27, 2011, Plaintiff filed a Response to Defendants Combined Motions (#92) with attached exhibits. Plaintiff filed additional supporting Exhibits (#93) under seal. On November 14, 2011, Defendants filed their Reply (#94) and also filed Exhibits (#95) under seal. The documents provided to this court include expert reports and peer-reviewed articles. Plaintiff also provided documents he received from Defendants which show 184 reported failures of the Profemur® neck of which 173 were failures of a long neck. Defendants have pointed out that the documentation shows that only 11 of these failures involved model PHA0-1244, which includes the failure of Plaintiff s prosthesis. Plaintiff s expert, James Pugh, a litigation consultant with a Ph.D. in Biomedical Engineering from Massachusetts Institute of Technology (MIT), issued an expert report on September 3, 2010. Pugh stated that it is my opinion to a reasonable degree of scientific certainty that the [Profemur®] prosthesis was unreasonably dangerous for its intended or reasonably foreseeable use in an individual such as [Plaintiff] in that the design features whereby the oblong taper of the neck is joined to the stem of the prosthesis by way of an oblong slot in the neck which results in micromovements between the oblong taper and the oblong slot which results in fretting of the materials thereby resulting in stress which causes fatigue failure of the oblong taper portion of the neck inside of the oblong slot. Pugh stated that the failures were not the result of a manufacturing defect, but rather of the design of the prosthesis where a neck with a tapered oval distal end is joined to the femur stem of the prosthesis through an oblong slot in the proximal end of the stem. Pugh stated that, until 5 2009, the necks were manufactured from a titanium alloy. He stated that cobalt chromium alloy assemblies in general showed higher strength when compared to the titanium alloy necks. Pugh expressed the opinion that these observations raise the possibility that the failures in question may be reduced by changing to cobalt chromium necks, which are stronger and may have reduced fretting. Pugh stated that the same basic problem of fretting and resulting stress leading to failure remains, but potentially may be at a substantially reduced incidence. Pugh stated: The unreasonably dangerous design condition can be eliminated by a one piece stem and neck assembly. The manufacturing of the one piece stem and neck assembly in different lengths and angles of the neck may be more costly than using different necks. However, this would eliminate the design defect in question and the suffering disability and expense resulting from failures. Plaintiff s expert, Carl Alstetter, who also has a degree from MIT and is a professor emeritus in metallurgical engineering at the University of Illinois, also issued a written report on September 3, 2010. In his report, Alstetter stated that he had conducted an investigation of the Wright Profemur® prosthesis that fractured in the distal end of the neck after implant into Plaintiff. Alstetter stated that [b]ased on my investigation of the failure, it is my opinion to a reasonable degree of scientific certainty that the prosthesis was unreasonably dangerous for its intended or reasonably foreseeable use in an individual such as [Plaintiff]. 6 Alstetter stated: The prosthesis design, which requires that the oblong taper of the neck be inserted into a tapered slot in the stem, can result in micromovements between the oblong taper and the oblong slot under the alternating stresses due to normal motion of the leg. The consequent fretting of the surface can lead to the degradation of the passive film on the metal and the initiation of a fatigue crack. Optical microscopic examination showed that the failure occurred by the propagation of a fatigue crack to a critical depth. Subsequent to this, a single load application caused a complete separation of the neck. Interestingly, the remainder of Alstetter s report is essentially identical to Pugh s report and includes the statement that the failures were not the result of a manufacturing defect. Plaintiff has also provided copies of articles written regarding the failure of modular prostheses, including a case study of Plaintiff s case written by Alstetter and the surgeon who performed Plaintiff s revision surgery, Chris J. Dangles, M.D. This article was published in 2010 and stated that the modular design is a relatively recent design promoted as giving the surgeon more options in controlling leg lengths, offset, and implant stability. 2 The article also stated that [i]mplant failure is a known occurrence and the benefits of modularity 2 Chris J. Dangles, M.D. and Carl J. Alstetter, ScD, Failure of the Modular Neck in a Total Hip Anthroplasty, The Journal of Arthroplasty 2010, Vol. 25 No. 7 at 1169.e5. 7 must be shown to outweigh the risks of this failure pattern. 3 The article concluded: The benefits of modularity allow for intraoperative adjustments to promote optimal positioning of the prosthesis. This should improve stability, decrease the dislocation rate, and assist in equalization of leg length. However, a well-fitting prosthesis that fails within a few years is neither what the patient reasonably expects or what is acceptable performance. Although the surgeon is not responsible for the design of a prosthesis, it is urged that surgeons consider potential design flaws when they are published in the literature.4 A paper written by faculty of Dalhousie University and published by the Canadian Arthritis Society concluded that the findings of this study demonstrate that this design of a modular neck total hip arthroplasty component is at a relatively high risk of early catastrophic failure. 5 An article published in 2010 concluded that [i]t is difficult to extrapolate the results from one patient beyond the case studied, but [i]t is suggested that long-necked modular stems, particularly when used with offset heads, should be used with caution, 3 Id. at 1169.e6. Plaintiff stated that this article opined that the advantages provided by a modular system are more than offset by the failures of the modular neck inside the femoral stem and that the Profemur prosthesis is an unsafe product. No such statements are included in the copy of the article provided by Plaintiff. 4 Id. at 1169.e7. 5 Wilson, Dunbar, Amirault, Farhat, Catastrophic Early Failure of a Modular Total Hip Arthroplasty Component, The Canadian Arthritis Society (undated). 8 especially in heavier patients, who place higher functional demands on the prosthesis. 6 Another article published in 2010 noted that modularity enables the surgeon to better optimize the patient s biomechanics and anatomy, but additional mechanical junctions can lead to corrosion processes resulting in fracture. 7 This article concluded that it appears that there is a risk of implant fracture at the stem-neck junction when double-modular devices are used, particularly when those with a long neck are implanted in heavy patients. 8 Yet another article published in 2010 focused on the use of titanium alloy for the neck of the modular prosthesis and concluded that a cobalt-based alloy increases the safety of the cone connection significantly. 9 A paper presented in 2009 stated that modular necks were a relatively new innovation in total hip arthroplasty, with several companies offering modular neck options. The paper stated that the proposed advantages of reduced impingement, reduced dislocation rate, and better reconstitution of leg length and offset are compelling. 10 The paper noted that few reports in the literature address the outcomes of these devices and 6 David A.J.

J (#92-7).) 9 that those that are published at best demonstrate equivalence to conventional total hip arthroplasty.11 The paper stated that there were numerous disadvantages to the new technology, with a fracture rate reported of 1.4%.12 The paper also stated that fractures occurred more frequently in heavy men and with the preponderance of fractures occurring around the 2-year mark. 13 This paper concluded that more research is required and stated that [g]iven the lack of literature to support the proposed benefits of proximal neck modularity, and the published theoretical and known complications with significantly increased costs, the available evidence would suggest that the proximal modular neck in [total hip arthroplasty] is a bridge too far. 14 Defendants have also provided expert reports in this case. Brad James, Ph.D., P.E., of Exponent Failure Analysis Associates, issued a report dated November 15, 2010. James stated that the findings in his report were made to a reasonable degree of engineering certainty. James stated that no manufacturing defects were observed and that [d]evice history records indicate the subject device conformed to Wright Medical s specified dimensional and surface finish requirements. James stated that [f]retting is a very wellknown issue in modular orthopedic implants, such as the subject device. James stated: Although modular orthopedic implants are well known to be 11 Id. at 1. 12 Id. at 1. 13 Id. at 1. 14 Id. at 4. 10 susceptible to fretting, modular systems allow distinct advantages in terms of fitting patient anatomy. The continued extensive use of various modular hip prostheses indicates the medical community generally believes the benefits outweigh the disadvantages . . . . Thus, the presence of fretting or fatigue fracture in a modular implant does not necessarily indicate the presence of a design or manufacturing defect. James stated that studies have shown a clear trend of patient weight with time-to-implant fracture time or fracture rate. James concluded that Plaintiff s weight contributed to the stresses placed upon his implant, and its eventual fatigue failure. James also concluded: The subject implant neck design has been on the market for more than ten years. In fact, a similar neck design has been in use as an implant in Europe since 1986. Wright Medical observed a fracture rate of approximately 0.0059% for long necks from 2002 through 2008. The fracture rate for all necks was reported to be 0.027%. These fracture rates for the Wright Medical PROFEMUR® device compare favorably with published literature, which includes most designs on the market. For example, the Swedish Hip Arthroplasty register reported that between 1979 and 2007 1.4% of hip revisions in Sweden were necessary because of hip implant fractures (475 out of 11 34,195 cases). The National Joint Registry for England and Wales stated 1% of all indications for hip revision surgeries in 2008 were because of implant fractures. Others have reported [total hip replacement] fracture rates between 0.23 to 91%. It is important to note these numbers include both monoblock and modular devices made by several different manufacturers. Thus, the PROFEMUR® fracture rates appear to be substantially lower than the rest of the hip replacement industry. Given the long service experience, the validation testing conducted by Wright Medical, and the low reported fracture rates, it can be concluded that the design of the subject neck is appropriate for its intended function. (Citations omitted.)15 James noted that Pugh had commented that changing to chromium alloy necks may reduce device failures. James acknowledged that it was true that cobalt chromium alloys have better fatigue resistance and are less susceptible to fretting than titanium alloys. However, James stated that other important design factors must be considered before simply switching alloys. James stated that the most common cause of total hip replacement prosthesis failure is aseptic loosening. James stated that, in fact, aseptic loosening failure rates in hip implants dwarf the rate of fatigue fracture. James pointed out that one factor in 15 This court notes that Defendants provided this court with James report only and did not include James resume or the list of documents he relied upon. 12 implant loosening is implant stiffness and cobalt chromium alloys have a significantly higher elastic modulus (stiffness) than titanium alloys. James stated that Pugh apparently only considered fretting and fatigue performance when he suggested switching alloys may reduce failures; such a statement is simplistic and does not consider the larger issues involved. James noted that, in addition, titanium alloys are typically considered to have superior biocompatibility compared to chromium alloys. He stated that just switching alloys is not a simple process; gains in one design area are typically balanced by reduction(s) in another. James also questioned Pugh s conclusion that a monolithic or one-piece design would eliminate the defect in question. James stated: Over 200 different one-piece implant variations would be required to replace the possible neck-stem combinations that exist because of the modularity of the PROFEMUR® Z-line. Further, one-piece implants are available from Wright Medical for surgeons to choose. Much of the literature cited in this report discusses failure of one-piece implants. As stated earlier, other factors, such as aseptic-loosening, result in far more hip implant revisions that do fractures. Stiffer, one-piece implants can be more prone to aseptic loosening than modular devices. Further, the flexibility provided by modularity can provide better patient fit and 13 biomechanics. The subject Wright Medical PROFEMUR® device is state of the art. There is no alternative hip implant design that would have eliminated the possibility of fracture in [Plaintiff]. Defendants expert, Jorge A. Ochoa, Ph.D. P.E., of Exponent Failure Analysis Associates, also issued a report dated November 15, 2010. This report set out information about Ochoa s qualifications, including a Ph.D. in Mechanical Engineering from Purdue University, and included citations to the sources he relied upon. Ochoa stated that his report was based on [his] education and experience as a biomechanical engineer and [his] experience designing, testing, and commercializing medical devices. In his lengthy report, Ochoa stated that the titanium alloy used in the Profemur® modular necks has a long history of clinical success in orthopaedic surgery due to its superior biocompatibility, fatigue properties, and strength and has a modulus of elasticity closer to that of bone than other alloys commonly used in orthopaedic implants. Ochoa stated that designing modular necks with a tapered junction out of alternative materials such as cobalt chromium alloys may increase the strength of the neck components themselves, but a simultaneous reduction in disassembly strength may be a resulting performance byproduct. Ochoa also stated: The benefits as well as the potential pitfalls of modularity are well understood and accepted by the orthopaedic community. Tradeoffs between strength and biomechanical performance are explicit with the use of modular transplants. Modularity enables 14 the surgeon to optimize the patient s biomechanics by accommodating anatomic variability, but the addition of junctions can lead to increased stresses, micromotion, fretting and corrosion at the modular interfaces, resulting in mechanical failure. (Citations omitted.) Ochoa stated that the fact that Plaintiff is obese would further exacerbate the incremental loading resulting from microseparation, even during activities of daily living. Ochoa summarized: As with any mechanical structure, there is always some risk of failure with an orthopaedic implant. While total hip replacement is largely successful in attaining the clinical goals of patients, it must be recognized that hip prostheses are manufactured from metal, ceramic, and polymeric materials. Therefore, no hip replacement component can be expected to withstand activity levels and loads similar to that of normal healthy bone for the lifetime of the patient. It is understood that artificial hip components will not be as strong, reliable, or durable as a natural human hip joint. Ochoa concluded that the subject PROFEMUR modular neck met its intended design and functional requirements, provided end user functionality and patient safety, and was not designed or manufactured in a defective manner. 15 ANALYSIS I. MOTION TO DISMISS Defendants have argued that, to the extent that Plaintiff sought to state a claim based on a failure to warn theory, the lack of factual allegations on this theory requires dismissal of the claim. In his response to Defendants Motion, Plaintiff has conceded that no failure to warn claim has been asserted. Therefore, Defendants request for dismissal of any failure to warn claim is GRANTED.16 Defendants also argued that, to the extent that Plaintiff sought to state a claim for a manufacturing defect, he has failed to do so and dismissal is warranted. In addition, Defendants argued, in the alternative, that they are entitled to summary judgment on any manufacturing defect claim brought by Plaintiff. This court concludes that, at this stage of the proceedings, it is more appropriate to consider whether Defendants are entitled to summary judgment on this claim. Therefore, Defendants request for dismissal of Plaintiff s manufacturing defect claim is DENIED as moot. II. MOTION FOR SUMMARY JUDGMENT A. SUMMARY JUDGMENT STANDARD Summary judgment is appropriate if the movant shows that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law. 16 This court notes that Plaintiff stated in a footnote that based on the defendants fallacious arguments, it has become apparent that there may be a failure to warn claim which plaintiff may ask leave to assert. This court reminds Plaintiff that the deadline for amending pleadings in this case passed long ago. Therefore, any such request would be untimely and would be denied. 16 Fed. R. Civ. P. 56(a); see also Celotex Corp. v. Catrett, 477 U.S. 317, 322-23 (1986). In ruling on a motion for summary judgment, a district court has one task and one task only: to decide, based on the evidence of record, whether there is any material dispute of fact that requires a trial. Waldridge v. Am. Hoechst Corp., 24 F.3d 918, 920 (7th Cir. 1994). In making this determination, the court must construe the evidence in the light most favorable to the nonmoving party and draw all reasonable inferences in favor of that party. See Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 255 (1986); Singer v. Raemisch, 593 F.3d 529, 533 (7th Cir. 2010). However, a court s favor toward the nonmoving party does not extend to drawing inferences which are only supported by speculation or conjecture. See Singer, 593 F.3d at 533. The party opposing summary judgment may not rely on the allegations contained in the pleadings. Waldridge, 24 F.3d at 920. [I]nstead, the nonmovant must present definite, competent evidence in rebuttal. Butts v. Aurora Health Care, Inc., 387 F.3d 921, 924 (7th Cir. 2004). Summary judgment is the put up or shut up moment in a lawsuit, when a party must show what evidence it has that would convince a trier of fact to accept its version of events. Koszola v. Bd. of Educ. of City of Chicago, 385 F.3d 1104, 1111 (7th Cir. 2004), quoting Johnson v. Cambridge Indus., Inc., 325 F.3d 892, 901 (7th Cir. 2003). Specifically, to survive summary judgment, the nonmoving party must make a sufficient showing of evidence for each essential element of its case on which it bears the burden at trial. Kampmier v. Emeritus Corp., 472 F.3d 930, 936 (7th Cir. 2007), citing Celotex Corp., 477 U.S. at 322-23. Conclusory allegations not supported by the record are not enough to 17 withstand summary judgment. See Basith v. Cook County, 241 F.3d 919, 928 (7th Cir. 2001). B. STRICT PRODUCT LIABILITY Plaintiff s claim is based upon strict product liability under Illinois law. Under this doctrine, strict liability is imposed upon a seller of any product in a defective condition unreasonably dangerous to the user or consumer or to his property. Calles v. Scripto-Tokai Corp., 864 N.E.2d 249, 254 (Ill. 2007), quoting Restatement (Second) of Torts § 402A, at 347-48 (1965). It is well established that to recover in a strict product liability action, a plaintiff must plead and prove that the injury complained of resulted from a condition of the product, that the condition was unreasonably dangerous, and that it existed at the time the product left the manufacturer s control. Mikolajczyk v. Ford Motor Co., 901 N.E.2d 329, 335 (Ill. 2008). A product may be found to be unreasonably dangerous based on proof of any one of three conditions: (1) a physical defect in the product itself (manufacturing defect); (2) a defect in the product s design (design defect); or (3) a failure of the manufacturer to warn of the danger or to instruct on the proper use of the product. Mikolajczyk, 901 N.E.2d at 335. This court has already dismissed any claim based upon the failure to warn. 1. PLAINTIFF S MANUFACTURING DEFECT CLAIM A manufacturing defect occurs when one unit in a product line is defective, whereas a design defect occurs when the specific unit conforms to the intended design but the intended design itself renders the product unreasonably dangerous. Salerno v. Innovative Surveillance Tech., Inc., 932 N.E.2d 101, 108 (Ill. App. Ct. 2010), citing Blue v. Envtl. Eng g, Inc., 828 N.E.2d 1128, 1137 (Ill. 2005). Generally speaking, manufacturing defects 18 result from qualities of a product not intended by the manufacturer. Mech. Rubber & Supply Co. v. Caterpillar Tractor Co., 399 N.E.2d 722, 723 (Ill. App. Ct. 1980). Defendants have argued that they are entitled to summary judgment on any claim included in Plaintiff s First Amended Complaint alleging a manufacturing defect because there is no evidence which supports such a claim. Defendants pointed out that Plaintiff s own expert, Pugh, conceded that Plaintiff s injuries were not caused by a manufacturing defect. In his response, Plaintiff has provided the supplemental opinions of Alstetter and Pugh. In their supplemental opinions, both Alstetter and Pugh contradicted their original reports, both of which stated that the failures were not the result of a manufacturing defect. In his supplemental opinion, Pugh stated that the only rational conclusion is that there is either a design defect and/or a manufacturing defect. Pugh explained that the extremely small design tolerances may result in manufacturing defects that is the distal end of the neck may be smaller than design tolerances and the oval slot of the stem may be larger than designed tolerances (emphasis added). Alstetter s supplemental expert report stated that he had reviewed additional information, including the list of failures provided by Defendants. Alstetter stated, in pertinent part, that: All information supports the conclusion that these failures are a result of fatigue crack propagation, possibly initiated by fretting in a corrosive environment caused by micromovements between the neck and the tapered slot in the stem. This uniform pattern 19 means there is either a design defect or a manufacturing defect or a combination that results in the degree of micro-movements necessary to accelerate fretting and failure. This court agrees with Defendants that Plaintiff has not come forward with any evidence that the hip prosthesis deviated in any way from Defendants intended design. Plaintiff s experts supplemental reports have provided only speculative opinions that there may be a manufacturing defect. In addition, these opinions contradict the experts original opinions regarding a manufacturing defect with little explanation. An expert who supplies nothing but a bottom line supplies nothing of value in the judicial process and does not save a party from summary judgment. Mid-State Fertilizer Co. v. Exchange Nat l Bank of Chicago, 877 F.2d 1333, 1339 (7th Cir. 1989); see also Weigel v. Target Stores, 122 F.3d 461, 468-69 (7th Cir. 1997). This court concludes that Plaintiff has provided no evidence showing the existence of a manufacturing defect and that Defendants are therefore entitled to summary judgment on Plaintiff s manufacturing defect claim. 2. PLAINTIFF S DESIGN DEFECT CLAIM A plaintiff may demonstrate that a product has been defectively designed in one of two ways. Calles, 864 N.E.2d at 255, citing Lamkin v. Towner, 563 N.E.2d 449, 457 (Ill. 1990). One way is to present evidence that the product fails to satisfy the consumerexpectation test. Calles, 864 N.E.2d at 255. Alternatively, a plaintiff may demonstrate a design defect by presenting evidence that the risk of danger inherent in the challenged design 20 outweighs the benefits of such design. Calles, 864 N.E.2d at 255. The latter test, which added the balancing of risks and benefits to the alternative design and feasibility inquiries, has come to be known as the risk-utility or risk-benefit test. Mikolajczyk, 901 N.E.2d at 336. Defendants have argued that they are entitled to summary judgment on Plaintiff s design defect claim because the evidence does not support Plaintiff s claim. In his Response, Plaintiff argued that there are genuine disputes of material fact as to his design defect claim under the risk-utility test and under the consumer-expectation test. a. CONSUMER-EXPECTATION TEST To prevail under the consumer-expectation test, a plaintiff must demonstrate that the product failed to perform as an ordinary consumer would expect when used in an intended or reasonably foreseeable manner. Calles, 864 N.E.2d at 256. However, Plaintiff has correctly recognized that if the evidence is sufficient to implicate the risk-utility test, a broader test which incorporates the factor of consumer-expectation is applied by the trier of fact. See Mikolajczyk, 901 N.E.2d at 352-53. Under the formulation set out in Mikolajczyk, consumer expectations are included within the scope of the broader risk-utility test. Show v. Ford Motor Co., 659 F.3d 584, 587 (7th Cir. 2011), quoting Mikolajczyk, 901 N.E.2d at 352. In this case, Plaintiff has presented evidence and argument regarding the riskutility test, so the consumer-expectation test is simply one factor incorporated into the riskutility test. See Mikolajcyzk, 901 N.E.2d at 352-53. Therefore, this court will consider this factor in its discussion of the risk-utility test. b. RISK-UTILITY TEST 21 Under the risk-utility test, the plaintiff must offer proof that the risk of danger inherent in the product design outweighs its benefits. Calles, 864 N.E.2d at 255. When the risk of harm outweighs the utility of a particular design, there is a determination that the manufacturer exposed the consumer to a greater risk of harm than is acceptable to society. Jablonski v. Ford Motor Co., 955 N.E.2d 1138, 1154 (Ill. 2011). Plaintiff bears the burden of proving that the risks outweigh the benefits. See Calles, 864 N.E.2d at 255. Plaintiff has asked this court to consider the factors set out by the Illinois Supreme Court in Jablonski in analyzing whether there is sufficient evidence to go to the jury based upon the risk-utility test. In Jablonski, the court set forth a nonexhaustive list of factors which may be relevant to the risk-utility analysis. Jablonski, 955 N.E.2d at 1154. These factors include evidence of (1) the availability and feasibility of alternate designs at the time of the product s manufacture; or (2) that the design used did not conform to the design standards in the industry, design guidelines provided by an authoritative voluntary organization, or design criteria set by legislation or governmental regulation. Jablonski, 955 N.E.2d at 1154, citing Calles, 864 N.E.2d at 260. Other factors that may be relevant include the utility of the product to the user and to the public as a whole, the safety aspects of the product including the likelihood that it will cause injury and the probable seriousness of the injury, and the manufacturer s ability to eliminate the unsafe character of the product without impairing its usefulness or making it too expensive to maintain its utility. Jablonski, 955 N.E.2d at 1154. The court in Jablonski noted that there are a myriad of factors that may be relevant to 22 the balance of risk and benefits, which may vary depending upon the unique facts and circumstances of each case. Jablonski, 955 N.E.2d at 1155. In applying the balancing test, the court must initially balance factors it finds relevant to determine if the case is a proper one to submit to the jury. Jablonski, 955 N.E.2d at 1155. This court notes that Jablonski was a negligence case rather than a strict product liability case. However, the court stated that the balancing test developed for strict liability claims, which examines whether a product is unreasonably dangerous, is essentially identical to the test applied in determining whether a defendant s conduct in designing a product is unreasonable. Jablonski, 955 N.E.2d at 1155. Plaintiff has argued that, based upon Jablonski, he must only submit enough facts so that this court may initially balance relevant factors to determine if the jury should decide this matter. Plaintiff suggested that the relevant factors in this case are: (1) the availability and feasibility of an alternate design; (2) the ability to eliminate the unsafe character without impairing its usefulness; and (3) the seriousness of the potential injury. As far as the first suggested factor, Plaintiff argued that Defendants could have used an alternate, monolithic, design at the time of manufacture to prevent the failure of Plaintiff s prosthesis. Plaintiff argued that he had established through the testimony of both of his experts that the modular design of the Profemur® prosthesis was a major cause of the failures. Plaintiff stated that his experts are not suggesting that a monolithic design would eliminate all failures but were testifying that a monolithic design would eliminate the particular design defect in this case. Plaintiff argued, citing Jablonski, he need not prove 23 that an alternative design would eliminate any and all failures as the defendants suggest. Plaintiff also contended that the same argument holds true in relation to his assertion that the use of a Morse taper and chromium-cobalt necks was an alternative design that was available and feasible. Plaintiff noted that Pugh s report stated that by changing the taper and metallurgical composition of the prosthesis neck, fretting and failures may be reduced. As to the second suggested factor, Plaintiff argued that he had shown that the alternative design is not overly costly to Defendants and would not impair the usefulness of the Profemur® prosthesis. Plaintiff stated that Defendants admit as much in their Motion for Summary Judgment by stating that Wright Medical already had over 200 monolithic options available on the market at the time of the implantation of the Profemur® prosthesis in the plaintiff. 17 In addition, Plaintiff argued that the third suggested factor, the potential seriousness of the injuries resulting from a failure, is important in this case. Plaintiff argued that, when the neck of the prosthesis fails, the entire prosthesis must be removed, including the femoral component which must be extricated from the femur. Plaintiff argued that this is a difficult procedure that frequently results in fractures of the proximal end of the femur. Plaintiff also contended that in almost every case a full revision surgery is necessitated. As support for 17 This court notes that Plaintiff is correct that Defendants made this argument in their Motion for Summary Judgment. Defendants cited to James report. However, James stated in his report that [o]ver 200 different one-piece implant variations would be required to replace the possible neck-stem combinations that exist because of the modularity of the PROFEMUR® Zline. Therefore, this court reads James report to state that over 200 different monolithic variations would be needed to replace the modular design of the Profemur® prosthesis, not that over 200 monolithic options are available. In any case, there is no dispute that many monolithic options are available, including monolithic prostheses manufactured by Defendants. 24 these arguments, Plaintiff referred to the information provided by Defendants regarding the failures of the Profemur® prosthesis. As far as the availability and feasibility of an alternate design factor, this court agrees with Plaintiff that a monolithic design was available at the time the Profemur® prosthesis was manufactured. However, based upon the expert reports and the published articles provided by Plaintiff, it is also clear that there are some advantages to the modular design over the monolithic design in the area of flexibility and providing more options in controlling leg lengths, offset, and implant stability. These reports and articles also show that there have been problems with failure of the modular necks, especially when a long neck is used and the prosthesis is implanted in an overweight individual. Plaintiff has provided evidence of 184 failures of the Profemur® prosthesis and that 173 of these failures involved the failure of a long neck. The problem with the evidence provided by Plaintiff is the complete lack of information from which this court could compare the risks of the modular design of the Profemur® prosthesis with the risks of the proposed alternate monolithic design. Defendants have challenged Plaintiff s contention that he only needs to show that the alternative design resolves the one specific defect alleged by Plaintiff and need not come forward with any evidence that the alternative design is generally safer or better. Defendants expert, James, stated in his report that the failure rate is approximately 0.0059% for long necks from 2002 through 2008. James stated that the fracture rate for all necks was reported to be 0.027% and the fracture rates for the Profemur® device compare favorably with the failure rate of other 25 types of prostheses, including monolithic prostheses. Plaintiff has not countered this statement in James report and has provided no information regarding failure rates. James stated that other factors, such as aseptic-loosening, result in far more hip implant revisions than do fractures and that [s]tiffer, one-piece implants can be more prone to aseptic loosening than modular devices. Therefore, while it may well be that a monolithic design would reduce or eliminate fretting and the resulting failure of the neck, there is evidence in this case that the use of the monolithic design could result in failure caused by aseptic loosening and other factors. Plaintiff has not directly disputed this and has provided no information from which this court can assess which design would result in the smallest percentage of failures. Plaintiff has asserted that he does not need to prove that the alternative, monolithic design would eliminate any and all failures. That may be true. However, the court stated in Jablonski, [i]t is not sufficient that the alternative design would have reduced or prevented the harm suffered by the plaintiff if it would also introduce into the product other dangers of equal or greater magnitude. Jablonski, 955 N.E.2d at 1158, quoting Restatement (Third) of Torts: Products Liability § 2, cmt. f, at 23 (1998). Based upon Jablonski, Defendants are correct that Plaintiff is required to show that the monolithic design did not have dangers of equal or greater magnitude. Plaintiff has not done so. The same is true regarding Plaintiff s proposed alternative design regarding a different taper and a chromium cobalt neck. Plaintiff has not addressed the evidence that, while a chromium cobalt neck may be stronger that a titanium alloy neck, titanium alloy has other 26 advantages. Plaintiff has provided no basis for determining whether the risk of the titanium alloy neck (less strength) outweighs the benefits of the titanium alloy neck (superior biocompatibility and elasticity closer to that of bone). Further, Pugh s report stated that the same basic problem of fretting and resulting stress leading to failure remains, but potentially may be at a substantially reduced incidence (emphasis added). This equivocal opinion is not sufficient to show that the proposed alternative design would actually be better. As far as Plaintiff s second suggested factor, Plaintiff has provided no comparison of the cost of the modular design as opposed to the monolithic design. Plaintiff s own expert, Pugh, stated that the manufacturing of the one piece stem and neck assembly in different lengths and angles of the neck may be more costly than using different necks. James stated that [o]ver 200 different one-piece implant variations would be required to replace the possible neck-stem combinations that exist because of the modularity of the PROFEMUR® Z-line. Therefore, this court concludes that Plaintiff has not shown that the alternative design is not overly costly to Defendants and would not impair the usefulness of the Profemur® prosthesis. In addition, Plaintiff has provided no evidence regarding the cost of using chromium cobalt alloy as compared to the cost of titanium alloy. In his discussion of his third suggested factor, Plaintiff has argued that the risk of harm is greater with the modular design. Again, however, Plaintiff has provided no evidence from which this court can analyze the harm caused by a failure of a modular prosthesis in comparison to the harm caused by a failure of a monolithic prosthesis. This court must also consider the consumer-expectation test as a factor in the risk27 utility analysis. Plaintiff testified at his deposition that he was told by his doctor that hip prostheses lasted, on average, about 20 years. However, Defendants have provided evidence that the product insert provided to Plaintiff s doctor stated that the patient should be warned that the prosthesis does not replace normal healthy bone, that the prosthesis can break or become damaged as a result of certain activity or trauma, has a finite expected service life, and may need to be replaced at some time in the future. Plaintiff and his doctor signed a consent before the implantation of the Profemur® prosthesis. By signing the form, Plaintiff s doctor stated that he had given Plaintiff an adequate and appropriate explanation of the nature and purpose of all the treatment and procedure(s) consented to above, possible alternative methods of treatment or procedures, the expected risks and benefits involved and the possibility of complications in the treatment and/or procedure(s) consented to and in alternative treatments or procedures. Plaintiff acknowledged that I understand the nature of the proposed procedure(s), attendant risks involved, and expected results as described above, and hereby request such procedure(s) be performed. Plaintiff therefore acknowledged there were risks involved. In addition, the evidence strongly indicates that the potential for prosthesis failure was somewhat greater for Plaintiff because of his weight.18 Defendants have also pointed out that Plaintiff s experts, Pugh and Alstetter, made no reference to the consumer-expectation test. Expert testimony is not required in all cases to demonstrate that a product was unreasonably dangerous under the consumer-expectation test; 18 It is possible that Plaintiff s doctor should not have chosen a modular prosthesis because of Plaintiff s weight and activity level. That is not an issue before this court. 28 however, expert testimony regarding the product s unreasonable dangerousness is required if the product is complex and beyond a lay jury s understanding. See Show, 659 F.3d at 58788; Gray v. Ford Motor Co., 2011 WL 4859995, at *6 (C.D. Ill. 2011). This court concludes that the evidence presented shows that the product at issue, a hip prosthesis, is a complex device which can fail for many reasons. Therefore, this is a product beyond a lay jury s understanding and expert testimony would be necessary for the consumer-expectation test to be considered as a factor favorable to Plaintiff under the risk-utility test. In arguing the consumer-expectation test, Plaintiff relied on a Supplemental Rule 26(a) Disclosure as to Dr. Chris J. Dangles, who Plaintiff stated is not a retained expert. As noted previously, Dangles performed the revision surgery on Plaintiff in 2008 after his hip prosthesis failed. According to the Disclosure, it is Dangles opinion, as a physician, that the advantages provided by a modular system are more than offset by the failures of the modular neck inside the femoral stem and accordingly, in his opinion as an orthopedic surgeon, the Profemur prosthesis is an unsafe product. This court concludes that Dangles conclusory opinion is not adequate expert testimony to allow the consumer-expectation test to be considered as a factor favorable to Plaintiff under the risk-utility test. Plaintiff has argued that the jury should assess the dangers of the [hip] prosthesis from the standpoint of an ordinary implantee, relying on Mele v. Howmedica, Inc., 808 N.E.2d 1026 (Ill. App. Ct. 2004). Plaintiff argued that [c]learly a reasonably jury can find that an ordinary consumer (implantee) could expect a hip prosthesis would last many years longer than four years and was thus unreasonably dangerous. 29 This court is not persuaded. In Mele, the plaintiff claimed that a device, the D-M system, used as part of his hip replacement was defective and, at trial, relied solely on the consumer-expectation test. Mele, 808 N.E.2d at 1032. Therefore, evidence regarding the risk-benefit test was not allowed at trial. Mele, 808 N.E.2d at 1032. The jury found the D-M system was unreasonably dangerous and awarded damages. Mele, 808 N.E.2d at 1035. The defendant appealed. Mele, 808 N.E.2d at 1035. The Illinois appellate court concluded that the plaintiff presented sufficient evidence to support the finding that an ordinary implantee would not anticipate this kind of danger from the D-M system. Mele, 808 N.E.2d at 1037. However, the appellate court also concluded that the artificial hip here, and the D-M system implanted as part of the hip surgery, is not a particularly simple device and [c]onsumers do not have an especially clear understanding of all the dangers inherent in the device or the level of safety they can reasonably expect from a product that performs the function of the D-M system. Mele, 808 N.E.2d at 1041. The court concluded that the case did not fall within the simple product exception to the application of the risk-utility test and therefore held that the trial court should have permitted defendant to present evidence that the product design cannot be considered unreasonably dangerous because its benefits outweighed its risks. Mele, 808 N.E.2d at 1041-42. The judgment was therefore reversed and the case was remanded for a retrial. Mele, 808 N.E.2d at 1042.19 Because the jury s verdict in Mele was reversed, this court concludes that Mele does 19 Subsequently, in Calles, the Illinois supreme court disagreed with Mele and other courts and determined that there was no simple product exception to the riskutility test. Calles, 864 N.E.2d at 260-63. 30 not support Plaintiff s argument that this case should be submitted to the jury for an assessment of the dangers of the hip prosthesis under the consumer-expectation test. The court in Jablonski stated that it is the plaintiff s burden to present evidence that the risk was foreseeable and that the risks inherent in the product design outweighed the benefits. Jablonski, 955 N.E.2d at 1157. Plaintiff has presented evidence that the risks of the modular design include the possibility of fracture of the neck of the prosthesis. The evidence in this case also shows that the benefits of the modular design include flexibility and providing more options in controlling leg lengths, offset, and implant stability. The modular design was developed to improve the fit of the prosthesis and to provide a prosthesis which is not as stiff as the monolithic design in order to reduce the failures of monolithic prostheses, including failures caused by aseptic loosening. In order to meet his burden under Jablonski, Plaintiff was required to provide evidence that the possibility of neck failure (the risk of the modular prosthesis design) outweighed or was greater than the benefits of the modular design (flexibility and better fit in order to reduce the possibility of the types of failures which have occurred in monolithic prostheses). Because Plaintiff has provided this court with no basis for comparing the risk and the benefits, he has not met his burden. In other words, in order to perform the initial balancing under the risk-utility test to determine it the case should go to the jury, this court must have something to balance. It cannot be enough to show that there is a risk without providing any way to balance the risk against the benefits. Because Plaintiff has not provided this court with evidence from which it can conduct 31 a threshold risk-utility analysis, this court concludes that Plaintiff has not adequately shown that the risks of the modular design used in the Profemur® prosthesis outweigh the benefits of the design. This court therefore agrees with Defendants that they are entitled to summary judgment on Plaintiff s design defect claim. IT IS THEREFORE ORDERED THAT: (1) Defendants Combined Motion to Dismiss and Motion for Summary Judgment (#90) is GRANTED in part and DENIED as moot in part. Judgment is entered in favor of Defendants and against Plaintiff on all of Plaintiff s claims. (2) The final pretrial conference scheduled on February 24, 2012, at 10:30 a.m. and the jury trial scheduled on March 5, 2012, at 9:00 a.m. are hereby VACATED. (3) This case is terminated.
