Gamma钉固定治疗367例股骨转子间骨折的疗效分析

Objective 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.
