摘要目的 探讨Gamma钉崮定治疗股骨转子间骨折的临床疗效.方法 2000年10月至2006年12月应用Gamma钉治疗367例股骨转子间骨折患者,男135例,女232例;平均年龄73.1岁(20～103岁);低能量损伤309例,高能量损伤58例;骨折根据AO分型:31-A1型117例,A2型208例,A3型42例.受伤至手术时间平均为4.7 d(1～17 d).术后定期摄片随访,采用自报告髋关节Harris评分(HHS)量表对骨折前和末次随访时的髋关节功能进行评估;记录患者对手术效果的整体满意度.结果 331例患者术后获4～106个月(平均16.1个月)随访.330例患者骨折获愈合,愈合时间平均为14.2周(12～24周);1例发生不愈合,愈合率为99.7%.28例患者术后发生并发症.根据自报告HHS量表评分:骨折前评分为31～90分,平均(84.6±10.0)分;末次随访时评分为19～90分,平均(75.8±12.8)分,差异有统计学意义(t=6.510,P=0.000).212例随访时间超过1年的患者术后1年对手术结果的满意度:满意135例(63.7%),比较满意67例(31.6%),一般6例(2.8%),不满意4例(1.9%).51.4%(109/212)的患者术后存在不同程度的疼痛或不适.结论 Gamma钉固定是治疗股骨转子问骨折的有效方法,但治疗后局部疼痛和髋关节评分下降仍较明显,手术效果还有待于进一步提高.

abstractsObjective To investigate the clinical effects of Gamma nails in treatment of intertroehanteric fractures.Methods From October 2000 to December 2006,we used Gamma nails to treat 367 patients with intertrochanteric fractures.They were 135 males and 232 females,aged from 20 to 103years(average,73.1 years).Low-impact injury was found in 309 patients and high-velocity injury in 58patients.By AO classification,there were 117 cases of type A1,208 cases of type A2 and 42 cases of type A3.The period from injury to operation was 4.7 days on average,ranging from 1 to 17 days.The postoperative hip radiographs and the patient's satisfaction were evaluated.The Harris hip score(HHS)self-report was used to compare hip functions before fracture and at the last follow-up. Results Of all the patients,331were followed up for 4 to106 months(mean,16.1 months).On average,99.7%of the fractures(330 cases)healed in 14.2 weeks(range,12 to 24 weeks).Postoperative complications occurred in 28 cases.The average HHS before fracture was 84.6±10.0 points(range,31 to 90),which significantly decreased at the finial follow-up to 75.8±12.8 points(range,19 to 90)(t=6.510,P=0.000).63.7%(135/212)of the patients rated the treatment outcome as excellent,31.6%(67/212)as good,2.8%(6/212)as fair,and 1.9%(4/212)as poor.51.4%(109/212)of the patients felt more or less pain in the hip. Conclusions Gamma nails are effective in treatment of intertroehanteric fractures.However,as the postoperative local pain is evident and the postoperative hip function decreases obviously,this operation needs to be improved.
