【Abstract】 Objective:To explore new internal fixation methods for the treatment of greater tuberosity(GT) fractures of the humerus and to develop low-cost fracture models for mechanical tests.Method:Design a new locking plate system based on the anatomy morphology as well as the clinical classification of the GT fractures.Develop a GT fracture model based on the Sawbones material.Results:The designed locking plate, endowed with low profile and high morphological conformance, can be equally employed in all three types′ GT fractures.Compared to conventional locking plates such as the PHILOS and mini-locking plate, the new locking plate is superior in accurately restoring the original position, reducing excessive compression of the fracture block as well as alleviating potential damage to the underlying soft tissues and blood supplies.The GT fracture model based on the Sawbones material serves as highly consistent and low-cost samples for the mechanical assessment of different fixation methods.Conclusion:The designed locking plate system and fracture model are superior to conventional internal fixation methods and mechanical test samples.更多还原
