Proximal humerus fractures present with different configurations in patients with varying comorbidities and expectations. Various treatment options are available for treating proximal humerus fractures. A good functional outcome with context to the early joint mobilisation and rigid fixation of the fracture can be achieved with PHILOS plate in proximal humerus fractures.Patients admitted with proximal humerus fractures as inpatient in department of orthopaedics were included in the study satisfying the inclusion and exclusion criteria.30 patients with proximal humerus fracture were treated by open reduction internal fixation with PHILOS plate. Improvement of Constant-Murley score at 6 weeks of 47.83 to 64.67 at 12 weeks(p=<0.001), 75.27 at 24 weeks(p=<0.001) and 78.33 at final follow up(p=<0.001). Most of the patients had excellent (43.3%) followed by good (33.3%), poor (16.7%) and fair (6.7%) outcome. Varus malunion 6(20%) was the most common complication.Proximal humeral internal locking system (PHILOS) is the implant of choice for treating displaced proximal humerus fractures which leads good functional outcome in patients.
