HIP RESURFACING LINKED TO INFERIOR IMPLANT SURVIVORSHIP FOR MANY PATIENTS.

HIP RESURFACING LINKED TO INFERIOR IMPLANT SURVIVORSHIP FOR MANY PATIENTS.

A United Kingdom study published online in the journal The Lancet finds that hip resurfacing may result in inferior implant survivorship compared to other surgical options in many patients. The authors analyzed data from the National Joint Registry for England and Wales (NJR) covering 434,560 primary total hip arthroplasties (THAs), of which 31,932 were resurfacings performed between 2003 and 2011. They found that resurfacing resulted in worse implant survival than did conventional total hip replacement  in men with smaller femoral heads and in women irrespective of femoral head size. Hip resurfacing only resulted in similar implant survivorship compared to other surgical options in men with large femoral heads.
