Osteonecrosis of the femoral head accounts for as many as 18% of total hip arthroplasties performed in western countries. The young age of affected patients and the potentially poor outcome have sparked an interest in alternative treatment modalities. Extracapsular placement of a vascularized fibular graft in the subchondral region of the femoral head has shown great promise as a treatment option. The authors have used this procedure in the treatment of 646 symptomatic hips, of all grades of osteonecrosis, with a follow-up of 1 to 17 years. The resultant 10-year survival rate of greater than 80% suggests that this procedure may be preferable to total hip arthroplasty for the young patient with osteonecrosis of the femoral head.
在西方国家，股骨头坏死在全髋关节置换手术中所占比例高达18%。患病患者的年轻化以及可能不佳的预后引发了人们对替代治疗方式的兴趣。在股骨头软骨下区域进行带血管腓骨移植的关节囊外植入，作为一种治疗选择已展现出巨大潜力。作者已将此手术用于治疗646例有症状的髋关节，涵盖所有等级的骨坏死，随访时间为1至17年。所得到的10年生存率大于80%，这表明对于患有股骨头坏死的年轻患者而言，该手术可能比全髋关节置换术更具优势。
