Abstract
In an eight year period, 31 patients with proximal femoral fractures resulting from sports accidents were treated by implantation of either a Gamma nail or a dynamic hip screw. Return to work or sports and the time to bone healing did not differ very much between the treatments. Gamma nailing was clearly the best with regard to stability and time to full mobilisation (4.5 days), but required 39 minutes to perform compared with insertion of a dynamic hip screw (27 minutes). The incidence of complications and malalignments did not differ very much between the two, although, when Gamma nailing was first used in the authors' clinic, more intraoperative complications occurred than with the dynamic hip screw. Stable pertrochanteric fractures may be treated with a dynamic hip screw. Unstable pertrochanteric or subtrochanteric fractures are treated with a Gamma nail at the authors' institution.
