Abstract: Objective: To explore the effectiveness of intraoperative reposition senile proximal humeral fractures by using bridging fixation of plate.Methods: All patients were treated with locking proximal humerus plate.During the operation,first of all,after reposition the proximal end of fracture,locking the proximal end of plate with a locking screw for fixation the proximal end of fracture.then,reposition the distal end of fracture by using bridging fixation of plate.Results: All the fracture fragments were fast,effectively reposited.Radiographic review around 4 weeks,8 weeks,3 months and 6 months after the operation,the fracture was not displaced,the fixation was not failure.After 6 months,according to Neer functional score evaluation:excellent in 12 cases,good in 3 cases,fair in 2 cases,poor in 1 cases,the excellent and good rate was 83.3%.Conclusions: Senile proximal humeral fracture can be fast,effectively reposited by using bridging fixation of plate
