Ten adult patients with the "silent hip lesion" of idiopathic ischemic necrosis of the femoral head were treated by the muscle-pedicle bone and cancellous bone graft procedure. They were followed postoperatively for 24 to 61 months (mean 42.4 months). Seven patients have remained asymptomatic, showing progressive healing of the hip lesions. Three patients were found to have failure as observed by collapsed femoral head or appearance of "crescent sign" in roentgenograms. Histologic sections of a collapsed femoral head revealed satisfactory incorporation of grafts into the surrounding bone of the femoral head and replacement of osteonecrotic bone extending from the muscle-pedicle graft to subchondral plate. The surgical procedure consisting of curettage of necrotic bone with a cancellous bone and muscle-pedicle bone graft can provide good results for Stages 1 and 2 of the idiopathic ischemic necrosis for an average follow-up of 3 1/2 years.
对10例患有股骨头特发性缺血性坏死“静息性髋部病变”的成年患者采用带肌蒂骨和松质骨移植手术进行治疗。术后对他们进行了24至61个月（平均42.4个月）的随访。7例患者一直无症状，髋部病变逐渐愈合。3例患者出现股骨头塌陷或X线片上出现“新月征”，手术失败。塌陷股骨头的组织学切片显示，移植骨与股骨头周围骨良好融合，坏死骨从带肌蒂移植骨延伸至软骨下板被替代。刮除坏死骨并植入松质骨和带肌蒂骨的手术方法，对于特发性缺血性坏死的1期和2期患者，平均随访3年半可取得良好效果。
