Femoral head viability following resurfacing arthroplasty. A clinical positron emission tomography study

Hip Int. Jan-Mar 2011;21(1):66-70. doi: 10.5301/hip.2011.6303.

Abstract

Hip resurfacing (HR) carries attendant risks of avascular necrosis (AVN) and femoral neck fracture. We used fluoride positron emission tomography (PET) scans to analyze bone metabolism 2-5 years after surgery in 35 cases. Three of the patients had been clinical failures. Using PET scans in the remaining 32 cases, 7 were found to have an area of non-viable bone in the femoral head. This was seen following both posterior and antero lateral approaches. Fluoride PET is a sensitive and useful method for evaluating bone metabolism following HR.
