Biomechanic of hybrid internal fixation system

摘要

Summary: We have combined the advantage of friction force of conventional plate and screw, angular stability of locking compression plate by design clearance between neck of screw and plate hold in order to reform plate fixation system which will assist in bettering patients' lives.Introduction: Nowadays, Bone fracture is treated by plate fixation system and Intramedullary nail. Plate fixation system is still extensively used, either locking compression plate or conventional plate screw (DCP, LC-DCP). However, these methods are limited success such as recovery time, plastic deformation, screw pul-lout and screw deformation. Therefore, we strived to develop and modify the novel hybrid internal fixation system (Figure 1) to improve biomechanic of plate fixation and to shorten the recovery time with full weight bearing. Herein, we wish to report biomechanical comparision of hybrid internal fixation and locking compression plate as well as fatique loading model.
