Background: The proximal humerus fractures are not easy to handle and are the second most common fractures of the upper extremity. The aim of the study is to analyze the treatment outcome of proximal humerus fractures using Philos Plate. Methods: The present study included 40 patients from May 2019 to May 2021 who underwent PHILOS plate fixation for displaced proximal humeral fractures using the PHILOS plating system in the department of Orthopaedics, IGIMS, Patna. Results: Patients were followed up for 6 to 18 months. The mean Constant shoulder score was 75 (range 28–88). 14 patients had a score exceeding 75,11were scored between 50 and 75, and 10 were below50. Constant scores in 2-, 3- and 4-part fractures were compared. Conclusion: In the present study, PHILOS plate fixation provided stable fixation with minimal metal work problems and enabled early range-of-motion exercises to achieve acceptable functional results. However, the choice of treatment should be based on patient age, functional requirements, bone quality and fracture pattern
