摘　　要：目的 :从生物力学角度探讨肱骨外髁骨折的发生机制和固定方法。方法 :通过电测实验法、三维光弹实验法 ,空间有限元分析法 ,研究肱骨外髁在各种体位下的受力情况和复位固定方法 ,三种实验方法互为验证 ,并应用于临床。结果 :66例肱骨外髁翻转骨折病人 ,经治疗优良率达 90 .9%。结论 :肱骨外髁骨折好发于肘关节半屈曲位跌倒 ,和肘关节伸直内翻位跌倒。骨折复位后固定在屈肘 60°～ 90°前臂旋后位最为稳定。本实验结论具有推广应用价值。Objective:From the agulation of biomechanics, discuss the occurance mechanism of fracture of the humerus lateral malleolus and the fixed method.Methods:Using electro-test, three-dimensional photoelasticty test, and space-limited component method to study the condition of force received by the humerus lateral mallelous in the difference postures and the giveback fixed method used. Three method attesteach other and are applied into clinic.Results:In 66patients with empicondylus lateralis of the humerus, the excellent and good rate was 90.9% after treatment.Conclusion:If fall in half flexion position and straight various position , empicondylus lateralis of the humerus more easily happens. In rotation-back position of forearm, when the elow joint was in 120°～90°flextion, the giveback fixed is stablest. This experiemtal conclusion is valuable to be extended in clinical application.
