As metal-on-metal hip implants continue to be scrutinized, here's the latest from Jim Dickinson in MD+DI's Washington Wrap-Up:

"A review of clinical trials, observational studies, and registries produced limited evidence on comparative effectiveness of various hip implant bearing combinations, according to an open source British Medical Journal report by researchers from CDRH and universities in the United States and Australia. “Results do not indicate any advantage to metal-on-metal or ceramic-on-ceramic implants compared with traditional metal-on-polyethylene or ceramic-on-polyethylene bearings,” the study concludes....They say they systematically reviewed the evidence as part of that project to determine the short- and long-term outcomes reported by patients undergoing hip replacement and the rates of revision after using implants with various bearings."
