Treatment of Femoral Head Osteonecrosis (Stages 2B 3 Ficat) Through Open Direct Core Decompression by Allograft Impaction and Light Bulb Technique

摘要

Femoral head avascular necrosis is the cause of paralyzing status of youth population. Initial diagnosis is the main element in treating the disease. Bone grafting and core decompression are the approved cures at the early steps of the disease. Hip replacement in a total manner is the common cure in the final stages. The optimal treatment in the intermediate stages is partially disputable. We investigated several patients with femoral head osteonecrosis cured with impacted cancellous allograft and open core decompression using the lightbulb technique.
