Comparison of dynamic hip screw and gamma nail: a prospective, randomized, controlled trial.

We report a prospective, randomized, controlled trial, comparing the results of treatment with a dynamic hip screw (DHS) and a gamma nail in 95 consecutive patients with peri-trochanteric fractures of the femur. The DHS was used in 48 patients, the gamma nail in 47. Clinical and radiological outcomes were similar, but the gamma nail was associated with a higher incidence of complications, in particular fracture of the femur below the implant in eight cases. This is consistent with previous reports, and we do not recommend the gamma nail for the treatment of peri-trochanteric femoral fractures.
