The aim of this study was to describe early results of a new internal locking system, PHILOS, used for the treatment of proximal humeral fractures.
Materials and methods
A chart and radiographic review of 25 cases that had proximal humeral internal locking system (PHILOS) plate for the treatment of proximal humeral fractures was performed.
Of the 25 cases, 20 went to union with a mean neck/shaft angle of 127.2°. Five cases required or were considered for revision surgery for non-union or implant failure. Of the 25 implants, 4 had screw protrusion into the gleno-humeral joint, 4 had screw loosening and backing out, and 1 plate broke without further trauma.
Our results suggest that PHILOS is an effective system for providing fracture stabilisation to bony union but awareness of potential hardware complications is essential.
