Metal-on-Metal Hips in the News
FDA to discuss risks and benefits of metal-on-metal hip replacements: Expert, patient recommendations being sought.
FDA's Orthopaedic Device Advisory Panel will meet in June 27-28, 2012 to seek expert scientific and clinical advice on the risks and benefits of metal-on-metal (MoM) hip replacement and resurfacing, including failure rates, metal ion testing, complications, considerations for post-op follow-up, etc. The panel will also hear potential patient and practitioner recommendations on the use of MoM systems and the management of patients implanted with such devices.
Medical Device Recall Actions: Stryker MITCH Hip Implants Authorities in New Zealand (NZ) initiated a recall of the MITCH THR hip implant, following indications from registry data that suggest a higher-than-expected failure rate in the metal-on-metal device at 3-years post-op. Of 41 patients who received the implant, 3 required revision due to failure. The implant was manufactured by Finsbury Orthopaedics and distributed in NZ by Stryker.
