INTRODUCTION Evaluation of the long-term performance of  implants used in trauma surgery relies on post-marked clinical studies since no registry based implant assessment exists .
The purpose of this study was to evaluate the evidence of performance of implants  currently used for treating proximal femoral fractures ( PFF ) in Denmark .
Internal fixation of femoral neck fractures. Dynamic Hip and Gouffon screws compared in 73 patients.
A prospect i ve , r and omized 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 )
