Abstract:
BACKGROUND:Many scholars researched the biomechanics of middle clavicle fracture plate fixation, but little researched the plate position. OBJECTIVE:To observe the biomechanical characteristics ofanterior and superior plates for clavicle fracture with three-dimensional finite element models. METHODS:Three-dimensional finite element models of clavicle fracture with anterior and superior plates were established. The stress after anterior and superior plate fixation was analyzed. The maximum stress and displacement of plate fixation for clavicular fracture were observed under compression, torsion and three-point bending. RESULTS AND CONCLUSION:(1) In the compressed condition, the maximum stressand maximum fracture displacement were similar between the superior and anterior plate fixation (P> 0.05). (2) Under clockwise twist condition, the maximum stress and maximum fracture displacement were smaler in the superior plate fixation group than inthe anterior plate fixation group (P< 0.05). (3) Under counterclockwise twist condition, the maximum stress and maximum fracture displacement were similar between the anterior and superior plate fixation groups (P> 0.05). (4) Under three-point bending condition, the maximum stress was similar between the superior and anterior plate fixation groups (P> 0.05). The maximum fracture displacement was bigger in the superior plate fixation group than in the anterior plate fixation group (P< 0.05). (5) These findings suggest that superior fixation of clavicle fracture reconstruction plate has more advantages than the anterior plate fixation.
