Internal fixation of femoral neck fractures. Dynamic Hip and Gouffon screws compared in 73 patients

Abstract

A prospective, randomized study comparing the Dynamic Hip screws and the Gouffon screws in the treatment of femoral neck fractures was terminated before the planned number of patients had been admitted, owing to a preponderance of early failure of the Gouffon screws (P 0.014); thus only 73 patients entered the study. After three years' follow-up, 25/38 Gouffon screws and 12/35 Dynamic Hip screws had failed. Six patients treated with Gouffon screws and 14 treated with Dynamic Hip screws had died. The outcome still favoured the use of Dynamic Hip screws (P 0.02).
