摘要
目的 :为解决股骨转子间骨折治疗方法多样性和繁杂性。方法 :采用股骨 2 0具 ,制成骨折模型 ,分别用 4种方法固定 ,经加载后测出各种固定物的抗弯及抗旋转强度 ;同时 ,总结随访病例 2 71例 ,分析治疗效果及并发症的发生率。结果 :动力髋螺钉固定最稳定 ,承载最大 ,其次是支架、麦氏鹅头钉 ,而单纯斯氏针最差。临床随访病例与力学实验结果相符。结论 :对于能耐受手术的病人 ,应首选动力髋螺钉 ;否则 ,应尽可能用支架固定。
Objective: To find an optimal method for the treatment of intertrochanteric fracture from multiple and complex treatment methods.Method:20 embalmed cadaver femoral specimens were collected and randomly allocated into four groups,the intertrochanteric fracture were made and each group was fixed with one of four techniques;After vertical load and deflective axis load test,the anti-rotation strength and anti-bending strength were tested.The clinical effect and incidence of complication of 271 cases of intertrochanteric fracture were analyses.Result: Dynamic hip screw(DHS) is the most stable technique of all,external fixators to be the second,and Steinmann pins was the poorest.The clinical effect was coincident with the result of the biomachanical test.Conclusion:To the patients,who can tolerate an operation,the authors prefer to using of DHS,and to the patients,who can not or will not receive an operation,we prefer to use unilateral external fixator.
