Introduction:Proximal humerus fractures are one of the common fractures encountered by orthopedic surgeons today. Management of articular fractures is more controversial because of complications like nonunion, shoulder stiffness and avascular necrosis. Open reduction and internal fixation allows early mobilization and functional recovery. Aim of this study is to evaluate the functional outcome of proximal humerus fractures treated with proximal humerus locking plates.  Methods: This study was conducted at Prathima Institute of Medical Sciences, Karimnagar from July 2015 to June 2017. 36 patients with displaced proximal humerus fractures were included in this study. All patients underwent open reduction and internal fixation with proximal humerus locking plate. Neer’s scoring system which is based on 100 points is used to assess the results of internal fixation.Results: Out of 36 patients, 12(34%) had excellent results (Neer’s score >89), 21(58%) cases had satisfactory results (Neer’s score between 80–88) and unsatisfactory result in 3(8%) cases (Neer’s score between 70–79). We had zero failure in our study. 3 patients had superficial infection, 3 patients had shoulder stiffness and 30 patients had no complications. Conclusion: We recommend open reduction and internal fixation of all displaced proximal humerus fractures with proximal humerus locking plate. Early mobilization, better fracture union rate and less disability make proximal humerus plating treatment of choice for all displaced proximal humerus fractures.
