The main advantage of hip resurfacing is bone conservation for patients likely to outlive a primary conventional hip replacement.Previous attempts at hip resurfacing failed predominantly because of the consequences of a high amount of wear of thin polyethylene acetabular components and poor femoral component fixation.With correct patient selection, surgeon education, and operative technique, survivorship at five years is comparable with that of traditional hip replacements.Hip resurfacing has its own unique set of complications, including a fractured neck of the femur. It is necessary to understand the risk factors prior to performing the procedure.
