Abstract: 【Abstract】〓Objective〓To investigate the effect of proximal humerus locking plate and proximal humerus anatomical plate on complex 3- and 4-part fractures of the proximal humerus (Neer classification) in the elders. Methods〓151 cases of proximal humeral fractures were included in the study and divided into proximal humerus anatomical plate group (A group, n=65 cases) and proximal humerus locking plate group(B group, n=86 cases) according to different operation methods. The patients of A group underwent fracture fixation by anatomical plate and those in B group received fracture fixation by locking proximal humerus plate. The treatment effect was evaluated in two groups and compared between two groups by Neer score and Constant score. Results〓The mean humerus healing time of B group was significant superior to A group (P<0.05). Neer score, constant score, pain, function, activity and total score of shoulder in B group were significant superior to those in A group in 1 year and 2 years after operation (P<0.05). Conclusion〓Proximal humerus locking plate and proximal humerus anatomical plate could be used for three-and four-part of proximal humeral fractures in the elders, but proximal humerus locking plate has andvantage for humerus healing time, functional rehabilitation.
