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 .
Prospective randomised controlled trial of an intramedullary nail versus a sliding hip screw for intertrochanteric fractures of the femur
Purpose The purpose of this prospect i ve r and omised trial was to assess whether an intramedullary nail is superior to a sliding hip screw in the treatment of multifragmentary intertrochanteric fractures Methods Eighty patients with a 31-A2.2 or A2.3 Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association ( AO/OTA ) intertrochanteric fracture were r and omly allocated to fixation with either the Gamma nail or the AMBI sliding hip screw device . Results All patients were followed up at one , three , six and 12 months postoperatively , except for nine who died . There was no statistical difference in Parker mobility score between groups . The Gamma nail group had significantly higher Barthel Index and EuroQol-5D ( EQ-5D ) scores than the AMBI group at 12 months . At the same time , the EQ-5D score had returned to its pre-operative values in the Gamma nail group but not in the AMBI group . There were no differences in mortality , radiation time and hospital stay . Duration of the operation , incision length and hip pain occurrence were significantly less in the Gamma nail group . Conclusions Few failures occur when unstable 31-A2.2 and A2.3 AO/OTA fractures are fixed with a sliding hip screw . Nevertheless , an intramedullary nail seems superior in reconstituting patients to their pre-operative state
