Internal Fixation of Displaced Proximal Humerus Fractures Using PHILOS: A Prospective Study

Background Proximal humeral fractures requiring surgical stabilization remain a therapeutic challenge particularly in elderly patients with unstable fracture types and diminished bone quality. Achieving stable fixation has been a challenge in proximal humerus fractures, especially with poor bone stock. PHILOS plate is the recent generation of angular stable implant, that reduces the risk of secondary dislocation of screws or fracture segments when the bone of the humeral head is osteoporotic and also preserves the biological integrity of the humeral head. Objective The aim of the present study was to evaluate functional outcome and complication rate after open reduction and internal fixation of displaced proximal humerus fractures by PHILOS plate. Methods This is a prospective study in which 33 patients with displaced proximal humerus fractures, who provided written informed consent to participate in the study were treated with PHILOS plate between October 2011 and November 2014. Fractures were classified according to Neer
