Abstract:
Objective To compare biomechanical properties of the traditional and novel locking compression plate （LCP） for treating femoral shaft fracture, so as to provide theoretical basis for selecting more effective bone plate. Methods The bending strength and fatigue tests on the plate were performed, and the finite element analysis on deformation, stress and life of the plate were conducted by using ANSYS Workbench. Results The average bending yield load and bending strength of the novel LCP were 1.4 times of that of the traditional LCP, and the average cycle times of the novel and traditional LCP were 106 and 47 091, respectively. The difference of service life for two LCPs was 33.8%. ConclusionsThe failure probability of the novel LCP is smaller than that of the traditional LCP, and the novel LCP has more effective biomechanical stability.
