成人发育性髋关节发育不良行全髋关节置换术后近期疗效的观察

目的探讨全髋关节置换术治疗成人发育性髋关节发育不良的近期临床效果。方法选择我院自2012年1月至2015年1月收治的14例成人发育性髋关节发育不良患者作为研究对象．均行全关节置换术，术中在延长软组织的基础上，正确安装假体，重建髋关节旋转中心的解剖结构及髋关节外展功能。结果所有患者均于术后进行22个月的随访．伤口均为一期愈合，未出现血管神经损伤及感染，髋关节Harris评分平均为（90．34±0．26），患肢平均延长（26．21±0．12）mm。结论全髋关节置换术是治疗成人发育性髋关节发育不良的有效方法，软组织松懈延长、合适假体的选择、重建脱臼与股骨近端的解剖结构是手术的关键。

Objective To investigate the total hip replacement surgery treatment of adult developmental dysplasia of the hip term clinical effects. Methods In our hospital from January 2012 to January 2015 were treated 14 cases of adults with developmental hip dys- plasia patients as research subiects underwent total joint replacement surgery, surgery to extend the soft tissue on the basis of correct installation false body, anatomy of the hip rotation center of reconstruction and hip abduction. Results All patients underwent postop- erative follow-up of 22 months, are a wound healing, vascular and nerve injury and infection does not appear, Harris hip score was （90.34±0.26）, limb extends the average （26.21±0. 12） mm. Conclusion Total hip arthroplasty is an effective treatment for adults with developmental dysplasia of the hip, soft tissue laxity extend, select the appropriate prosthesis, dislocation and reconstruction of the anatomy of the proximal femur is the key to the surgery.
