建立锁定接骨板固定肱骨外科颈骨折有限元模型,观察并分析接骨板在受力形变后肱骨外科颈骨折处能否提供支撑力而导致的不同应力分布情况,为接骨板断裂失效分析提供学术依据和理论支持.初步判定该接骨板无法承受病人120o外展状态下肱骨外科颈不发生接触时的受力,应考虑更换接骨板类型或避免外展至120o以降低接骨板断裂的概率.

The FE model of proximal humeral locking plate was established and analyzed to provide academic support of the proximal humeral locking plate failure. The stress distributions of the locking plate were observed under the situations of the fracture area providing support and without support. In summary, this type of locking plate cannot afford the stress at 120o abduction position under the situation of fracture area provides without support. In order to reduce the probability of locking plate failure, it is recommended that using other type of locking plate instead or avoiding 120 degree abduction of the patient.
