Wright Medical filed a citizen's petition with the FDA to block pre-market approval of rival Smith & Nephew's Birmingham metal-on-metal hip implant. Wright Medical (NSDQ:WMGI) sought to block rival Smith & Nephew (FTSE:SN, NYSE:SNN) from getting its Birmingham metal-on-metal hip implant into the U.S. marketplace, according to filings with the FDA. As the federal watchdog agency in 2006 was reviewing Smith & Nephew's pre-market approval application for the device, which was the first metal-on-metal hip implant, Wright filed a citizen's petition alleging that the study behind the PMA application was inadequate to prove safety and effectiveness.
