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 .
A Comparison of Proximal Femoral Nail Antirotation and Dynamic Hip Screw Devices in Trochanteric Fractures
This prospect i ve , r and omized study compared the functional outcome and complications associated with a proximal femoral nail antirotation ( PFNA ) device with those of a traditional extramedullary device , the dynamic hip screw ( DHS ) , in patients with trochanteric fracture . A total of 121 patients were r and omized to the PFNA group ( n = 58 ) or the DHS group ( n = 63 ) .  Perioperative information and complications were recorded , and assessment s of functional outcome were made . The DHS group required a longer operative time and was associated with greater blood loss than the PFNA group . The re-operation rate was lower in the PFNA group compared with the DHS group , especially in patients with unstable fractures , although there was no statistically significant difference in the overall complication rate between the two groups . There were no significant differences in functional outcome between the PFNA and the DHS groups . In conclusion , the PFNA device is useful in the treatment of trochanteric fractures
