Introduction: Treatment of proximal humerus fractures always holds a dilemma for the treating surgeon.
Aim: To assess the functional outcome of proximal humerus fractures treated with Proximal Humerus Internal Locking System (PHILOS) plating.
Material and Methods: Fifty three consecutive patients were treated with PHILOS plating between August 2013 and August 2014. The inclusion criteria were skeletally matured patients with closed fracture proximal humerus with displacement >1 cm and varus angulation of >450. Severely comminuted fractures, open fractures and valgus impacted fractures were excluded from the study. The outcome was assessed using Neer's scoring system.
Results: The average age was 54.3±5.8 years. As per the Neers classification system, there were 6 (11.32%) 1-part, 19 (35.85%) 2-part, 17 (32.085) and 11 (20.75%) 3 and 4-part fracture respectively. Average surgical duration was 94±10.2 minutes. Radiological union was seen at 12±4.6 weeks. There were 2 (3.77%) cases of varus collapse. Three (5.66%) cases had screw back out, which was later revised and had a favourable outcome. As per the Neer's scoring system, 7 (13.21%) cases had excellent results, 37 (69.81%) had satisfactory, 6 (11.32%) had unsatisfactory while 3 (05.66%) cases had poor outcomes.
Conclusion: PHILOS plating has a good functional outcome. However, proper patient selection, thorough knowledge of the anatomy and biomechanical principles are the pre-requisites for a successful surgery.
