Core decompression for avascular necrosis of the femoral head.

The results of core decompression as the sole treatment for Ficat stages 1, 2 and 3 avascular necrosis of 51 femoral heads in 39 patients were studied. The mean follow-up time was 24 months (6-47 months); 19 hips (38.8%) were good and 30 hips (61.2%) had failed (two hips were lost to follow-up). The good results as stated in the literature could not be obtained, but we believe core decompression can delay the need for total hip replacement in avascular necrosis of the femoral head.
