Purpose of study : – To highlight possible complications following Philos plating of proximal humeral fractures.

Methods : – 10 patients with proximal humeral fractures operated upon in period 2003–2004 were reviewed. Analysis was undertaken with observer xray review and using radiograph analysis software.

Results : – In 3 cases the fracture had collapsed significantly resulting in cut out of the proximal screws. One case required implant removal within a month following initial surgery. In another case the radiographs were not standardised views to compare the amount of collapse. The other cases went onto healing without any complication.

Conclusions : – As the Philos plate is a fixed angle implant the degree of collapse expected must be accounted for when fixing the implant this is especially important in osteoporotic patients or in those with a high degree of comminution. In these circumstances high placement of the plate and long proximal screws should be avoided.
