Mid-term results of internal fixation of proximal humeral fractures with the Philos plate
Accepted 5 March 2009.
Abstract
Objective
To report our experience from the use of the Philos® plate for the treatment of three- and four-part proximal humeral fractures and to investigate factors influencing the final outcome.
Materials and methods
Between April 2005 and September 2007, 29 Philos plates were implanted in 17 women and 12 men, with a mean age of 62.3 years (range: 28–80 years). Positioning of the plate was performed under fluoroscopic control, through a deltopectoral approach and with the patient in the beach chair position. 27 patients were available for follow-up (mean: 17.9 months; range: 12–39). Follow-up included plain shoulder radiographs and functional assessment with Constant–Murley score.
Results
Healing of the fracture occurred uneventfully within 6 months. In three patients, humeral head collapsed due to aseptic necrosis after fracture healing and the plate had to be removed in two cases. In one patient, fracture healing occurred in >10° varus displacement. The clinical result according to the Constant–Murley score was 86 points (range: 58–112).
Conclusions
Internal fixation with the Philos plate seems to be a reliable option in the operative treatment of upper end humeral fractures, especially in osteoporotic bone. It allows secure fracture fixation and quick shoulder mobilisation, while quick and uneventful fracture healing and very satisfactory clinical results are achieved.
