We have not posted for a while—that day job can really get in the way sometimes—so we agreed to tackle the ridiculously long decision in Christiansen v. Wright Med. Tech. Inc., MDL No. 2329, 1:13-cv-297-WSD, 2015 U.S. Dist. LEXIS 115601 (N.D. Ga. Aug. 31, 2015), as a bit of penance. This act may be appropriate given the recent Day of Atonement and, much like long Yom Kippur services during a fast, the decision drags on, repeats itself, has some highs and lows, and maybe induces some confusion and a touch of a headache. While we are not looking for a scapegoat, some of the reasoning for why the issues were presented how they were presented and why they were decided is lost on the reader, at least this reader. (Much like the original meaning of Azazel, to where/whom the original scapegoat was to be sent by Aaron. Or maybe not at all like that.) As a combination Daubert and summary judgment order on a bellwether case from an MDL for a product, a metal-on-metal hip implant, for which there is considerable litigation on similar products made by other manufacturers, there will likely to attempts to extend various parts of this decision to other cases. So, we will resort to the dreaded use of subheadings in discussing it.
Background
Plaintiff had a left hip replacement in 1995 with a device that used a ceramic femoral ball, a polyethylene liner, and a metal acetabular shell. In 2006, plaintiff had her right hip replaced with the defendant’s product, which utilized a ball and cup each made of cobalt-chromium with no liner. In 2012, plaintiff started experiencing pain in her right hip and, within a week, had a revision surgery where the defendant’s product was explanted (and presumably something else was implanted). All three surgeries were done by Dr. Lynn Rasmussen, who happened to have been consulting with defendant on designing hip implants in between the second and third surgeries. In doing the third surgery, Dr. Rasmussen observed what he called “metallosis” (sometimes “metalosis” in the records and briefs), but did not send any explanted tissue or material for pathological evaluation. Plaintiff sued under a range of product liability theories based on the risk of “metallosis.” Thereafter, plaintiff named at least ten experts to weigh in on causation and defect in some form or other, most of whom relied to some degree on Dr. Rasmussen’s characterization of what he saw—and defendant filed a bunch of Daubert motions. Plaintiff filed a “motion for partial summary judgment” that preemption and the learned intermediary doctrine did not apply to her claims and, at the court’s request, the defendant filed a motion for summary judgment on all the claims that plaintiff did not drop. An affiliated defendant also filed for summary judgment on different grounds. There were some other motions we are ignoring, but everything was addressed in one big decision.Continue Reading Making Sense of the Rule 702 and Summary Judgment Orders in A Metal-on-Metal Hip Implant Bellwether Case
