Texas lawyers representing thousands of plaintiffs in Dallas federal court in what’s known as the Pinnacle System hip-replacement cases expect pre-trial battles to heat up at a scheduled Sept. 10 conference before U.S. District Judge Ed Kinkeade.

In the past 18 months, plaintiffs have filed more than 4,000 complaints related to the Pinnacle hip-replacement system in the U.S. District Court in the Northern District of Texas. That massive wave of complaints follows a U.S. Judicial Panel on Multidistrict Litigation decision in 2011 to assign Kinkeade, who is in the Northern District, to preside over designated MDL proceedings for the Pinnacle System cases.
