Sequelae of large-head metal-on-metal hip arthroplasties: Current status and future prospects

[摘要] Large-head metal-on-metal (MoM) bearings were repopularised in the late 1990s with the introduction of modern hip resurfacing (HR), followed shortly afterward by large metal head total hip arthroplasty (THA). The introduction of MoM articulations led to a worldwide increase in the use of MoM hip arthroplasty, which subsequently saw a sharp decline. MoM was rapidly adopted in the early 2000s until adverse reports in the literature led to medical device alerts which were issued by government regulatory agencies and national and international organisations, leading to post-marketing surveillance and the discontinuation of these implants.1-3 It is estimated that more than one million large-head MoM hips have been implanted to date. MoM arthroplasties are among the least successful modern hip implants.
