锁定加压钢板治疗骨质疏松性股骨转子间骨折

目的：探讨用锁定加压钢板治疗骨质疏松性股骨转子部骨折的疗效和手术技巧。方法：自2006年2月至2009年10月，治疗伴有骨质疏松的股骨转子骨折49例，男22例，女27例；年龄63-90岁，平均（74．68±5．94）岁。用锁定加压钢板固定29例，动力髋螺钉固定20例。根据X线片及超声骨密度测定判定骨质疏松，观察比较两组手术时间、术中失血量、X线透视次数、骨折愈合时间、术后开始离床时间。结果：49例均获随访，时间6-35个月。两组手术时间、接受X线次数、骨折愈合时间及术后开始离床时间差异无统计学意义（t=1．347，1．603，1．973，1．032，P〉0．05）；与DHS组比较，LCP组术中失血量较少（t=2．14，P〈0．05）。结论：锁定加压钢板是治疗骨质疏松股骨转子部骨折的有效方法，具有创伤小，患者恢复快等优点，尤其适合老年患者，但要严格掌握操作程序。

Analysis of treatment of osteoporotic intertrochanteric fracture of femur with the locking compression plate (LCP)

Objective: To investigate the therapeutic effect and operating technique on the treatment of osteoporotic intertrochanteric fracture of femur with the locking compression plate(LCP). Methods: From Feb. 2006 to Oct. 2009,49 patients with osteoporotic intertrochanteric fracture of femur were treaded with different internal fixation methods,concluded 22 males and 27 females with an average age of(74.68±5.94) years old ranging from 63 to 90 years. Among them,29 patients were treaded with LCP,and the other 22 cases with DHS. According to X-ray and Ultrasound bone mineral desity,all cases were diagnosed in osteoporosis. The operative time,blood loss,fluoroscopy exposure frequency,bone healing time and the time of first away from bed. Results: All patients were followed up from 6 to 35 months. The operative time,fluoroscopy exposure frequency,the bone healing time and the time of being away from bed were compared between two groups,there were no statistical differences(t=1.347,1.603,1.973,1.032,P>0.05). As compared with DHS group,the intraoperative blood loss in LCP group was less than that of DHS group,there were statistical differences (t=2.14,P<0.05). Conclusion: The LCP is an effective method in the treatment of intertrochanteric fracture of femur. The method has the advantages such as small wound and early recovery,especially appropriate for older patients. But the procedure as well should be demanded strictly.
