Abstract

Background: Proximal humeral nail and PHILOS plate fixation offer anatomical fracture reduction and stable primary fixation, facilitating rapid healing and immediate postoperative rehabilitation without prolonged immobilization Objectives: To compare the functional outcomes among proximal humerus fractures treated with Proximal Humerus Multiloc Nailing versus PHILOS plating in Neer 2 part and 3 part proximal humerus fractures. Materials and Methods: A randomized controlled trial was conducted in the Department of Orthopaedics at a tertiary-care institute. Adults ?18 years with displaced NEER two or three-part PHFs, intact shoulder function pre-injury, and able to consent were enrolled. Participants were randomized (odd–even method) into: Group A—MultiLoc nailing; Group B—PHILOS plate fixation. Functional outcomes, radiographic union, intraoperative metrics, and complications were assessed at 6 weeks, 3 months, 6 months, and 12 months. Results: The majority of patients were aged 50–60, with falls (40.3%), RTAs (37.7%), and direct blows (20.9%) being the leading injury mechanisms mirroring typical PHF epidemiology. Both surgical approaches significantly improved CMS over time, but the MultiLoc group showed consistently higher scores: preop 35.3?±?2.1 vs. 34.0?±?2.6 (ns); 3 months 50.7?±?3.8 vs. 47.0?±?3.5 (p?
