国产Wagner SL假体置换治疗高龄EvansⅢ型粗隆间骨折的疗效分析

Curative effect of domestic Wagner SL prosthesis replacement for Evans Ⅲ intertrochanteric fracture in elderly patients

目的回顾性分析国产Wagner SL假体置换治疗高龄粉碎性粗隆间骨折短期疗效。方法选取国产Wagner SL假体置换治疗的高龄EvansⅢ型粗隆间骨折患者17例,其中男6例,女11例,75～84岁,平均79.8岁。选取同期骨水泥型长柄假体置换治疗的高龄EvansⅢ型粗隆间骨折患者12例,其中男4例,女8例,77～85岁,平均81.1岁。比较两组手术时间、术中术后出血量、卧床时间、术后功能评分等。结果两组年龄、性别、体质量指数、骨质疏松程度等差异无统计学意义（P〉0.05）,国产Wagner SL假体组手术时间、术中出血量少于骨水泥型长柄假体组,差异有统计学意义（P〈0.05）,两组术后引流量、卧床时间及Harris评分差异无统计学意义（P〉0.05）。结论国产Wagner SL假体置换治疗高龄粉碎性粗隆间骨折手术创伤小、治疗效果好,相对进口假体住院费用低。

Objective To retrospectively analyze the curative effect of domestic Wagner SL prosthesis replacement in elderly patients with Evans Ⅲ intertrochanteric fracture（ IF）. Methods A total of 17 elderly patients（ 6 male and 11 female,age 75 ～ 84 years,average 79. 8 years） with Evans Ⅲ IF who underwent domestic Wagner SL prosthesis replacement,and another 12 controls（ 4 male and 8 female,age 77 ～ 85 years,average 81. 1 years） with Evans Ⅲ IF who received cemented long-stem prosthesis replacement were observed. The operation time,intraoperative blood loss,postoperative blood loss,postoperative bed time,postoperative function score of the two groups were compared.Results There were no statistical significance between the two groups in terms of age,sex,body mass index and degree of osteoporosis（ P〈0. 05）. The operation time and intraoperative blood loss of Wagner SL prosthesis replacement group was significantly less than that of the control group（ P〈0. 05）. There was no statistical significance in the volume of drainage,postoperative bed time and Harris hip scores（ P〉0. 05）. Conclusion Domestic Wagner SL prosthesis replacement for elderly patients with comminuted intertrochanteric fracture（ CIF） has advantages of minimal invasion,rapid recovery,good efficacy and low hospital expenses. Therefore,it is worth of wide clinical application.
