It has always been an engima for the management of such fractures because of numerous muscles attachment and paucity of space for fixing implant in fracture of proximal humerus. The object of the osteosynthesis is to reduce the displacement (usually rotation) of each fragment and hold it in place with an implant and allowing early mobilization. Objective: To evaluate the functional outcome of proximal humerus fractures treated with proximal humerus locking plates (PHILOS). Material and Methods: Using Neer's classification twelve patients of proximal humerus fractures were treated by open reduction and internal fixation with PHILOS plate through deltopectoral approach and were evaluated by Neers criteria at the end of follow up. Results: All the fractures of proximal humerus who met the inclusion criteria were treated with (PHILOS) plate. Proximal humerus fracture is common in age group of 31 to 40 years (41%). 8 out 12(58%) patients were male. In the present study 8(67%) cases had 2 part fracture; 3(25%) cases had 3 part fracture and one case (8%) had 4 part fracture. In our study we had 4 Excellent (34%) and 7 satisfactory (58%) results and 1 had unsatisfactory (8%) according to Neer's criteria. Out of 12 patients, 2(17%) had complication.1 patient (8.5%) had superficial infection and 1 patient (8.5%) had stiffness of the shoulder Conclusion: From our study it can be safely recommended that for proximal humerus fractures, PHILOS plating is a good choice of surgical treatment.
