自体骨髓血及髂骨颗粒混合物移植治疗晚期股骨头缺血性坏死

Treatment of late avascular necrosis of the femoral head with combined autologous bone marrow and impaction hip autologous bone graft

评价浓缩骨髓结合自体髂骨植骨治疗股骨头缺血性坏死效果。回顾分析接受此方法治疗的35例晚期股骨头缺血性坏死的临床资料,采用美国宾州大学分期系统,评价方法根据Harris评分系统。35例患者中Ⅲ期8例,Ⅳ期23例,Ⅴ期4例。术前Harris评分43～72分,平均49分。随访时间在1年以上者。平均2年零3个月。2例患者疼痛明显,股骨头植骨区无明显塌陷,但明显出现骨关节炎,改为全髋置换,此2例患者在治疗时处于病变Ⅴ期。5例患者影像学显示股骨头外形较术前比较有所塌陷,但患者主观感觉很好。其余患者股骨头基本保持术后外形,疼痛主诉消失或者明显减轻,总有效率94%(33/35人)。Harris评分92分1人,80～89分17人,70～79分3人,70分以下2人。浓缩骨髓结合自体髂骨植骨是治疗中晚期股骨头缺血性坏死的一种比较确切的方法之一。

To evaluate the treatment effect of the late avascular necrosis of femoral head with concentrated autologous bone marrow and impaction autologous bone graft. The clinical data of 35 patients with late avascular necrosis of femoral head treated with the above methods was analyzed retrospectively with the University of Pennsylvania staging system, and evaluated with Harris hip score system. Among the 35 patients, there were 8 at stage Ⅲ, 23 at stage Ⅳ and 4 at stage Ⅴ. The preoperative Harris hip scores ranged from 43-72 with the average scores of 49. The patients were followed up for at least one year with the mean time of 2 years and 3 months. Two patients （preoperative at stage Ⅴ ） had received total hip replacement duo to severe pain and ostarthritis. The imageology in 5 patients showed that the femoral head appearance collapsed little compared with that before operation, but their subjective feelings were well. All the femoral heads of left patients remained the shape after operation, complains of pain disappeared or lessened. The overall successful rate was 94% （33/35）. In Harris scale, there was 1 patient with 92 scores, 17 with 80-89 scores, 3 with 70-79 scores and 2 patients 〈 70 scores, Concentrated autologous bone marrow combined impaction autologous bone graft is one of the effective methods for late avascular necrosis of femoral head.
