Nowadays, Bone fracture is treated by plate fixation system either locking compression plate or conventional plate screw (DCP, LC-DCP). However, these methods are still limited success in aspect of recovery time. Therefore, we strived to develop and modify the novel hybrid internal fixation system. To measure biomechanic properties of hybrid internal fixation system compare with locking compression plate. Experimental study for designing and test static loading model and fatique loading model IN adult femur bone of cadaver donor age 30-50 yrs. Study hybrid internal fixation system and locking compression plate in 3 pairs adult femur bone of cadaver donor and test the static loading model and fatique loading model to examine the displace of bone and irrevesible deformity. :
Compare locking compression plate,hybrid internal fixation system the displacement of static loading model have p=0.109 , fatique loading model have p = 0.785 and irreversible deformity have p= 0.180. From this study , we demonstrated a novel hybrid internal fixation system. There were no statistic significant difference between locking compression plate and hybrid internal fixation system but there is significant aspect of cost 4 time lower cost so we encourage use in developing countries.
