摘要:

背景:研究认为螺旋型髋臼假体在全髋关节置换时的稳定性较好。
目的:探讨Zweymüller双锥面螺旋髋臼假体全髋关节置换治疗成人发育性髋关节发育不良的早期临床疗效。
方法:收集2011年1月至2013年6月38例(48髋)成人发育性髋关节发育不良采用Zweymüller假体行全髋关节置换的患者,观察临床疗效。
结果与结论:38例患者无一例失访,随访时间21-46个月(平均42.3个月),1例发生患肢深静脉血栓;置换后末次随访Harris评分和Charnely评分较置换前明显提高;术中平均截骨长度为(2.42±0.48) cm,患肢平均延长(4.58±1.15) cm;置换后X射线检查显示截骨面愈合良好,假体无下沉及松动,置换后髋臼位置良好,截骨面愈合时间3-11个月(平均5.3个月),髋臼假体覆盖范围92.5%,具有较好初期稳定性;手术治疗优良率90%,患者满意率84%。提示Zweymüller螺旋髋臼假体有设计合理、初始稳定性良好、术后松动率低、患者满意度高等优点。但是由于患者数较少,随访时间较短,只能进行早期临床疗效评价,对于其中远期治疗效果还需继续随访评价。

Abstract:

BACKGROUND: Spiral acetabular prosthesis has good stability during total hip arthroplasty.
OBJECTIVE: To observe the early therapeutic effect of Zweymüller spiral acetabular prosthesis in total hip arthroplasty for patients with developmental dysplasia of the hip.
METHODS: Totally 38 patients (48 hips) with developmental dysplasia of the hip received total hip arthroplasty with Zweymüller spiral acetabular prosthesis from January 2011 to June 2013 were selected. The clinical effect was observed after the operation.
RESULTS AND CONCLUSION: A total of 38 patients were followed up for 21-46 months (averagely 42.3 months). One case suffered from deep venous thrombosis. Harris scores and Charnely scores apparently increased after surgery compared with that before surgery. The mean length of the osteotomy was 2.42±0.48 cm, and the mean extended length of the affected limb was 4.58±1.15 cm. X-ray films showed that there was no disunion of the osteotomy, no subsidence and loosening of prosthesis. The position of the acetabulum was suitable. The healing time of bone graft was 3-11 months (averagely 5.3 months). The coverage of the acetabular component was 92.5%, with a good initial stability, and the excellent rate of the operation was 90%. The satisfaction rate of patients was 84%. These results indicate that the Zweymüller spiral acetabular prosthesis has the advantages of reasonable design, good initial stability, low loosening rate and high satisfaction degree.  However, the number of cases of this study was relatively small, the follow-up time was short, and only the short-term effect was evaluated. Thus, the midterm and long-term effects need to be observed by the follow-up evaluation.
