Valgus reduction of trochanteric fractures.

A total of 663 patients in whom a Dynamic Hip Screw was inserted for internal fixation of an intertrochanteric femoral fracture were studied prospectively to determine the optimum position of reduction. Results show that those fractures in which a valgus reduction was performed had a reduced incidence of fixation failure. For those fractures fixed in a varus position, 28 per cent of screws cut-out from the femoral head. A valgus reduction is, therefore, to be recommended in preference to fixation in an anatomical position and a varus position must be avoided.
