Numerical investigation of fracture impaction in proximal humeral fracture fixation with locking plate and intramedullary nail

摘要

Introduction Fracture impaction is a surgical technique used to support the fractured humerus with locking plate or intramedullary nail when treating proximal humeral fractures. However, few studies have investigated the mechanical difference between fracture impaction with locking plate and with intramedullary nail. The mechanism of fracture impaction to increase stability is still unclear. The aim of this study was to use numerical methods to compare the biomechanical effect of treating proximal humeral fracture.
