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 .
Intramedullary fixation of intertrochanteric hip fractures: a comparison of two implant designs. A prospective randomised clinical trial.
We report the results of a prospect i ve r and omized clinical trial comparing the Gamma 3 nail with the ACE trochanteric nail for the treatment of pertrochanteric femoral fractures . One hundred and twelve consecutive patients were enrolled in the study : 61 patients were treated with the Gamma 3 nail , 51 with the ACE trochanteric nail .  The two groups were matched for age , fracture type and preoperative Merle d'Aubigné hip score . All patients were followed up clinical ly and radiographically on a regular basis between 6 weeks and one year postoperatively . Twenty-six patients ( 23 % ) died within the first postoperative year . Six patients were lost to follow-up . In each group , two patients were revised due to mechanical failure . Nonunion did not occur . The mean postoperative hip scores in the Gamma 3 and the ACE group were 14.19 and 14.12 respectively , with no significant difference ( p = 0.92 ) . Walking ability was adequately restored in approximately 80 % of the patients . Both implants appeared as safe and effective methods of treatment for intertrochanteric hip fractures
