全髋关节置换术治疗先天性髋关节脱位并股骨头缺血性无菌性坏死临床观察

目的：探讨全髋关节置换术治疗先天性髋关节脱位并股骨头缺血性无菌性坏死的临床效果。方法选取16例先天性髋关节脱位并股骨头缺血性无菌性坏死患者，其中双侧髋关节病变10例，单侧病变6例，对26个病变部位进行全髋关节置换术（ THA）治疗，随访观察手术效果。结果手术均成功，术后未出现骨折及血管、神经、肌肉的损伤，患者出院后关节活动功能恢复达到预期目标，行走不受限，基本恢复了日常生活。肢体长度延长3～5 cm，平均3．4 cm。 Harris评分由术前36．2分恢复至术后90．1分。结论对于先天性髋关节脱位并股骨头缺血性无菌性坏死患者，全髋关节置换术是较好的手术治疗方法。

Clinical observation of total hip arthroplasty in the treatment of congenital dislocation of the hip and femoral head ischemic necrosis

Objective To explore the effects of total hip arthroplasty in the treatment of congenital disloca-tion of the hip and femoral head aseptic necrosis.Methods 16 cases of congenital dislocation of the hip and femoral head ischemic necrosis patients,10 cases of them were bilateral hip lesion,6 cases with unilateral lesions,total hip replacement in 26 lesions（ THA） treatment,Follow up was used to observe the effect of the operation.Results All patients had succeeded in the operation.There were no postoperative fractures and vascular,nerve damage,muscle. Patients were discharged after recovery of joint function reached the expected target, walking was not restricted, restoration of the basic daily life.Limb length extension of 3-5cm,the average 3.4cm.Harris score by preoperative average 36.2 points back to 90.1 points after operation.Conclusion For the patients of congenital dislocation of hip joint combined with femoral head ischemic necrosis,total hip replacement arthroplasty were a good method for them.
