ABSTRACT
Clavicular fracture is a common upper limb fracture. Because of its special anatomical structure, it directly affects the function of the shoulder joint. The different injury mechanisms of clavicular fracture affect the mechanical effect of internal fixation, so the selection of internal fixation method has been puzzling orthopedists. As a modern computer based mechanical analysis, finite element analysis application in the internal fixation of clavicular fracture can not only clarify the pathogenesis of fractures, biomechanical properties of internal fixators and complications of fractures, but also provide guidance for preoperative planning. Therefore, it is beneficial to preoperative planning and individualized selection of surgical methods, and is expected to become an indispensable part in preoperative planning for clavicular fracture. In this paper, the pathogenesis, related influencing factors, selection of internal fixation and postoperative complications of clavicular fracture based on finite element analysis and problems during finite element analysis were reviewed.
