Abstract:
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 120 degrees 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.
