After a British study found poor results from hip resurfacing on some men and on women in general, researchers say the technique shouldn't be used on women and men should be evaluated carefully before having resurfacing. Researchers said resurfacing and metal-on-metal bearings should be examined closely before new implant technology is released.
Hip resurfacing has been used as an alternative to total hip replacement, but the study found resurfacing was less effective on men with smaller thigh bones and 5-year implant survival was worse for all women. Study findings were published online in The Lancet.
A companion editorial said the study's results show “a class effect in the failure of hip resurfacing devices.”
