摘要目的 回顾性分析应用带血管蒂大转子骨瓣转移覆盖塌陷的股骨头来重建股骨头治疗晚期股骨头缺血性坏死(ANFH)的临床疗效. 方法 随访我院2008年1月-2012年12月期间行股骨头再造的患者21例,进行临床及影像学评估.临床评估采用Harris髋关节评分标准,评价术后患髋功能改善情况,所有患者均定期随访(术后3个月、6个月及之后每年复查一次)X线片,了解骨瓣愈合及股骨头修复情况,确定是否有分期进展,根据有无改行关节置换决定临床生存率. 结果 21例患者全部获得随访,随访时间24 ～ 72个月,平均47个月.术后Harris髋关节功能平均评分为(82.8±7.1)分,较术前(52.4±4.3)分有明显提高,差异有统计学意义(P＜0.05),根据Ficat骨坏死分期标准进行影像学评价,本组病例中8髋于术后24～48个月(平均33个月)出现分期进展,塌陷加重,影像学成功率为61.9％,6例于术后18～48个月(平均34个月)因进行性股骨头塌陷或严重的髋关节疼痛或两者兼有而改行人工全髋关节置换术,其中FicatⅢ期占25％(4髋),Ⅳ期占40％(2髋),临床生存率为71.4％. 结论 应用带血管蒂大转子骨瓣转移覆盖塌陷的股骨头重建股骨头治疗晚期ANFH是一种较好的方法,值得临床推广应用.

abstractsObjective To analyze retrospectively the clinical efficacy that the application with vascularized greater trochanter to reconstruct the collapse of femoral head necrosis.Methods Followed-up the data of 21 patients who underwent reconstruction of the femoral head from January,2008 to December,2012,by this we made the clinical and radiological assess,Harris hip scoring system was used to evaluate the situation of hip function.All patients were followed up regularly for X-ray film (after 3 months,6 months and then be reviewed once a year),by the film we assessed the bone healing and repair of the femoral head,and determined whether had the progress in phases.The clinical survival was decided by receiving or not the arthroplasty.Results All 21 patients were followed up for 24-72 months,with an average of 47 months.The postoperative Harris hip score was 82.8 ± 7.1 points,compared with the preoperative,the score improved significantly (average 52.4 ± 4.3 points for preoperative),the difference was statistically significant (P ＜ 0.05).Based on Ficat stage for osteonecrosis,8 patients in this group had progress after 24 to 48 months (mean 33 months),whose femoral heads got collapse worsened.The radiographic success rate was 61.9％.Six cases received arthroplasty in 18 to 48 months (mean 34 months) due to progressive collapse of the femoral head or severe hip pain,or both.FicatⅢ contained 25％ (4 hips),and Ⅳ had 40％ (2 hips),the clinical survival rate was 71.4％.Conclusion The application with vascularized greate.r trochanter transfer coverage to rebuild the collapse of the femoral head in patients with osteonecrosis is a good way.It' s worthy to be applied.
