Background: There is still a lot of debate, regarding the most effective ways to treat displaced proximal humerus fractures. Numerous xing techniques been developed for proximal humerus fractures (like percutaneous pinning, tension band wiring, screw xation, conventional plate, T buttress plate, locking plate, prosthetic replacement). Close reduction & percutaneous k-wire xation having advantage being minimal invasive, less soft tissue stripping, with less blood loss, hence useful in elderly patients. But implant of choice for treating displaced proximal humerus fractures is locking plate because it provides absolute anatomical xation with angular stability. This study evaluates prospectively, the functional outcome following PHILOS vs percutaneous pinning in proximal humerus fractures. 30 patie Methods: nts were enrolled for study based on OPD & trauma centre admissions based on inclusion & exclusion criteria. Patients were grouped into two groups based on consecutive sampling. Group A (15 Patients) {ODD} includes rst patients, Group B (15 Patients) {EVEN} includes second patients. Group A operated with proximal humerus internal locking system (PHILOS), & Group B with percutaneous K-wire xation. Functional outcome was assessed by NEER's Score. Results: Functional outcome at end of 6 months, based on Neer's Score, in group A, came out to be excellent in 12 (80%) and satisfactory in 3 (20%). In group B, excellent in 5 (33.3%) and satisfactory in 10 (66.6%). In Group A, 2 patients developed complications i.e., 1 patient had shoulder stiffness & 1 patient had supercial infection. In Group B, 6 patients developed complications i.e., 4 patients had shoulder stiffness only, 1 patient had supercial infection only and 1 patient had both shoulder stiffness and supercial infection. PHILOS plate provides excellent Conclusion: functional outcome with minimal complications for displaced proximal humerus fractures compared to percutaneous k wire xation
