Abstract: Introduction: Proximal humeral fractures account for 5% of all fractures. Displaced and unstable fractures are difficult to manage. New plating techniques have been developed to improve stability.
Aim: Aim of this study was to evaluate functional outcome and complication of Proximal Humeral Internal Locking System (PHILOS) in proximal humeral fractures.
Materials and Methods: Thirty patients of proximal humeral fractures were treated by open reduction and proximal humeral internal locking system (PHILOS) plate fixation. Out of thirty patients of proximal humeral fractures are 24 Male and 6 Female with age group of 22years to 62years. Fractures were caused by low-energy trauma (fall from height) 14(46.66%) patients, RTA 10(33.33%) patients and Direct trauma 6(20%) patients. All fractures were closed with no associated injuries and according to Neer classification, classified as 2-part (n=17) and 3-part (n=13). Functional outcomes and shoulder range of movement were assessed based on the Constant scoring system.
Results: Out of 30 cases 24 (80%) healed satisfactorily, one case of 3-part fracture in whom there was fracture collapse and one case 3-part fracture developed non-union, one case of 3-part fracture screw penetration of the humeral head at 8 weeks developed avascular necrosis and two cases with valgus 3-part fracture who had malunion. No wound infections and vascular injuries. One case with axillary nerve palsy recovered within 2 months.
Discussion: In our study constant shoulder score was 70. 14 patients had a score above 75, 12 were scored between50-75 and 4 were below 50.
Conclusion: PHILOS plate provided stable fixation in displaced proximal humeral fracture.
