Abstract: Purpose: To study the functional outcome of proximal humerus internal locking system plating in displaced proximal humerus fractures.
Materials and Methods: Prospective interventional study a total of 30 patients admitted in VIMS, Ballari with displaced proximal humerus fractures between August 2020 and August 2022 were included in the study. Patients were treated with proximal internal locking system plating and followed up at 6 weeks, 12 weeks and 6 months and were evaluated for functional outcome using Constant and Murley shoulder scoring system.
Results: Excellent outcome was noted in 20%, Good in 47%, fair in 23% and poor in 10% cases. 90% of patients had clinical and radiological union in 3 months. The range of motion showed gradual improvement in successive follow ups.
Conclusion: PHILOS plate provides a high degree of angular and axial stability eliminating screw loosening and backout. PHILOS plate showed significantly less plastic deformation subsequent to torsional and axial forces.
