Analysis of outcome of avascular necrosis of femoral head treated by core decompression and bone grafting.

Femoral head is the most common bone affected by avascular necrosis. Core decompression procedure, when done in the initial stages, before collapse, may arrest or reverse the progress of avascular necrosis and thereby may preserve the normal femoral head. Hence, we have analysed the clinical, functional and radiological outcome of core decompression and bone grafting in patients with Osteonecrosis of the femoral head (ONFH) upto stage IIB (Ficat & Arlet).
