Hip resurfacing is a form of arthroplasty which has been eveloped as an earlier intervention alternative to total hip replacement (THR). The potential advantages of hip resurfacing include less bone removal (bone preservation), a potentially lower number of hip dislocations due to a relatively larger femoral head size, and possibly easier revision surgery for a subsequent total hip replacement device because a surgeon could have more bone stock available to work with. The potential disadvantages of hip resurfacing are femoral neck fractures (rate of 0-4%), aseptic loosening, and metal wear.
