Hip resurfacing arthroplasty is a bone conserving procedure that can be advocated for patients who may outlive conventional total hip replacements. Secondary benefits include improved joint stability, ability to undertake sporting activities, ease of revision to conventional hip replacement and emotional benefit to patients who do not feel that have not lost bone unnecessarily. Hip resurfacing has been attempted since the 1950’s onwards. Throughout the 1960’s and 1970’s clinical results were inferior to those of stemmed hip replacement and the procedure was largely abandoned by the mid 1980’s. The failure of early resurfacing designs has been attributed to the use of inappropriate materials, poor implant design, inferior manufacturing tolerances and poor instrumentation. Since the advent of the current generation of metal on metal hip resurfacing in the mid 1990’s, there has been a resurgence of interest in the procedure. Encouraging early and mid-term results are now being published for appropriately selected cohort of patients. However, fracture neck-of-femur, avascular collapse of the residual femoral head, femoral neck thinning and sensitivity to metal debris are causes of continuing concern. Current developments of resurfacing seek to address these issues and extend the indications of bone conserving hip replacement to a wider patient population.
