Introduction: 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. Results: Of the 25 cases, 20 went to union with a mean neck/shaft angle of 127.2 degrees . 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. Conclusions: Our results suggest that PHILOS is an effective system for providing fracture stabilisation to bony union but awareness of potential hardware complications is essential.

Fractures of the hook of the hamate have rarely been reported. They have usually resulted from blunt trauma or a sharp strike against the hamate hook while swinging a golf club, baseball bat, or tennis racquet. Patients present with acute onset of pain localised over the ulnar aspect of the wrist and reduction in grip strength. In the case reported here, the patient complained of gradual onset of pain on the ulriar aspect of the wrist after altering his grip for serving in tennis. Once the diagnosis was made, the fracture was treated conservatively and the patient made a complete recovery. [ABSTRACT FROM AUTHOR]
