The present study was undertaken to document outcomes of cementation of a highly cross-linked polyethylene (PE) liner into a well-fixed acetabular metal shell in 36 hips. All operations were performed by a single surgeon using only one type of liner. Patients were followed for a mean of 6.1 years (range, 3-8 years). Mean Harris hip score improved from 58 points preoperatively to 91 points postoperatively. There were no cases of PE liner dislodgement or progressive osteolysis. 1 hip (2.8%) required revision surgery for acetabular cup loosening with greater trochanteric fracture. Complications included 1 peroneal nerve palsy and 1 dislocation. The results of this study and previous reports demonstrated that cementation of highly cross-linked PE liner into well-fixed metal shell could provide good midterm durability.
本研究旨在记录36例髋关节中高交联聚乙烯（PE）内衬与固定良好的髋臼金属杯进行骨水泥固定的结果。所有手术均由同一位外科医生进行，仅使用一种类型的内衬。患者平均随访6.1年（范围3 - 8年）。Harris髋关节平均评分从术前的58分提高到术后的91分。没有PE内衬移位或进行性骨溶解的病例。1例髋关节（2.8%）因髋臼杯松动伴大转子骨折需要翻修手术。并发症包括1例腓总神经麻痹和1例脱位。本研究结果及既往报道表明，将高交联PE内衬骨水泥固定于固定良好的金属杯中可提供良好的中期耐久性。
