摘　　要：背景:近年来股骨假体周围骨折已经成为是全髋关节置换后最常见的并发症之一,Vancourver B1型骨折因为股骨柄假体稳定同时无明显骨缺损,目前多主张积极行内固定治疗。目的:探讨Synthes线缆系统置入内固定治疗全髋关节置换后Vancouver B1型股骨假体周围骨折的临床效果。方法:2009年5月至2012年10月南通市第一人民医院骨科采用Synthes线缆系统置入内固定治疗18例全髋关节置换后Vancouver B1型股骨假体周围骨折患者,女10例,男8例;年龄45-80岁,平均(62.67±8.67)岁。治疗后第1,3,6个月复诊,按Harris评分标准评定髋关节功能,满分为100分,≥90分为优,80-89分为较好,70-79分为良,<70分为差。结果与结论:18例患者均获得随访,18例获得随访6-43个月,患者平均骨折愈合时间为(19.06±4.04)周。18例治疗前Harris评分为(22.3±3.6)分,治疗后第1,3,6个月髋关节Harris评分均较治疗前显著提高(P<0.01),髋关节功能恢复良好。提示Synthes线缆系统能最大程度恢复股骨正常解剖结构,操作简便,损伤小,稳定性强,安全性高,是治疗Vancouver B1型股骨假体周围骨折的理想方法。BACKGROUND：Recently, periprosthetic femoral fractures have been a common complication after total hip replacement. Vancouver type B1 periprosthetic femoral fractures commonly received internal fixation due to stable femoral prosthesis and less bone defects. OBJECTIVE：To evaluate the effect of the application of Synthes cable system in the treatment of Vancouver type B1 periprosthetic femoral fractures after total hip replacement. METHODS：From May 2009 to October 2012, 18 patients with Vancouver type B1 periprosthetic femoral fractures were treated with Synthes cable system in the Department of Orthopedics, Nantong First People’s Hospital. There were 8 males and 10 females with an average age of （62.67±8.67） years ranging 45 to 80 years. They received a further consultation at 1, 3 and 6 months after treatment. The function of hip joint was evaluated by Harrris evaluation standard：ful marks, 100 points, ≥ 90 points, excellent;80-89 points, better;70-79 points, good; RESULTS AND CONCLUSION：Al 18 patients were fol owed up for 6 to 43 months. Mean healing period was （19.06±4.04） weeks. Harris score was （22.3±3.6） points before treatment in 18 cases. Harris score was higher significantly at 1, 3 and 6 months after treatment compared with that before treatment （P〈0.01）, and the recovery of hip function was good. Results indicated that Synthes cable system could help to restore the normal anatomic structure of femur in the greatest extent, showing simple operation, little injury, high stability and high safety. It is an ideal method for treating Vancouver type B1 periprosthetic femoral fractures.
