The clinical evidence behind the current implants used for proximal femoral fractures is weak considering the number of implants used worldwide .
Sporadic evaluation is not sufficient to identify long term problems .
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 .
Proximal Femoral Nail Antirotation versus Gamma3 nail for intramedullary nailing of unstable trochanteric fractures. A randomised comparative study.
The purpose of this study was to compare the clinical results and the complication rates of a new generation of two intramedullary fixation devices : Proximal Femoral Nail Antirotation ® ( PFNA ) and Gamma3 ® . We conducted a prospect i ve r and omised multicentre trial of 61 patients who underwent a PFNA fixation treatment ( 31 patients ) or a Gamma3 nail ( 30 patients ) . We documented the fixation failure complications as well as data of the surgical procedure , the clinical and functional outcomes ( the EuroQoL5 question naire , the Katz index score , the Short Form 36 ( SF-36 ) , and the Harris Hip Score ) and the plain radiographic parameters at 3,6 and 12 months follow up . The PFNA and Gamma3 fixation devices were similar in terms of complication rates . The risk for experiencing a postoperative complication after Gamma3 nailing was 40 % versus 45 % after PFNA fixation . At the 6-month and 1-year follow-up evaluations , there were no significant differences in terms of range of motion , clinical scores and radiological outcomes
