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 .
Comparing two intramedullary devices for treating trochanteric fractures: A prospective study
Background Intertrochanteric fractures are surgically treated by using different methods and implants . The optional type of surgical stabilization is still under debate . However , between devices with the same philosophy , different design characteristics may substantially influence fracture healing . This is a prospect i ve study comparing the complication and final functional outcome of two intramedullary devices , the intramedullary hip screw ( IMHS ) and the ENDOVIS nail . Material s and methods Two hundred fifteen patients were r and omized on admission in two treatment groups . Epidemiology features and functional status was similar between two treatment groups . Fracture stability was assessed according to the Evan 's classification . One hundred ten patients were treated with IMHS and 105 with ENDOVIS nail .  Results There were no significant statistical differences between the two groups regarding blood loss , transfusion requirements and mortality rate . In contrast , the number of total complications was significantly higher in the ENDOVIS nail group . Moreover , the overall functional and walking competence was superior in the patients treated with the IMHS nail . Conclusions These results indicate that the choice of the proper implant plays probably an important role in the final outcome of surgical treatment of intertrochanteric fractures . IMHS nail allows for accurate surgical technique , for both static and dynamic compression and high rotational stability . IMHS nail proved more reliable in our study regarding nail insertion and overall uncomplicated outcome
