补片在髋关节融合后全髋置换重建软组织张力中的应用

背景：越来越多的髋关节整合后患者要求行全髋置换，但些类患者长期软组织失用，为防止置换后假体脱位，置换过程中往往需要进行软组织张力的重建。 目的：探讨医用聚丙烯疝修补网在髋关节融全全髋关节转换重建软组织张力中的应用。 方法：2007-01/2011-01对21例髋关节融合患者进行了全髋关节置换，置换过程中纠正下肢的不等长，恢复患者股骨的偏心距后，肌肉无法缝合，采用补片重建软组织的张力。 结果与结论：置换后1年Harris评分（83.8±6.4）分，屈髋活动度（79.54.6）°.置换后有2例行走时仍需要手杖，置换前伴有的下腰痛、同侧膝关节痛和对侧髋关节痛的症状均明显缓解，仅有2例患者仍有肢体不等长。置换时间超过5年的9例患者均未见假体松动表现。结果可见正在重建软组织张力的过程中应用补片对患者置换后髋关节功能恢复及假体的稳固非常重要。

Application of patch in the total hip arthroplasty to reconstruct soft tissue tension after hip fusion

BACKGROUND： More and more patients required total hip arthroplasty （THA） after hip fusion. However, due to apraxias of tissue with long-term, patients need reconstruct soft tissue tension during replacement to prevent dislocation of the prosthesis after replacement. OBJECTIVE： To discussion the application of patch in the THA to reconstruct soft tissue tension after hip fusion. METHODS： From January 2007 to January 2011, 21 patients with hip fusion were treated with the THA. Unequal length of lower extremities was corrected, muscle was unable to close after restoring the patient＇s femoral offset. Patch was used for reconstructing soft tissue tension during the operation. RESULTS AND CONCLUSION： At 1 year after operation, Harris was （83.8＋6.4 score）, flexion of hip activity was （79.5°±4.6°）. Two patients still needed walking stick after the operation. Lumbago, side gonalgia and the opposite side hip pain before the operation were obviously alleviated, and only two patients still had leg length discrepancy. Over 5 years after the operation, nine patients were not found the loosed performance. The patch plays an important role in the soft tissue tension reconstruction and is very important to hip function recovery and prosthesis stability.
