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 hip screw versus sliding hip screw for unstable intertrochanteric femoral fractures in the elderly.
We report a r and omised , prospect i ve study comparing a st and ard sliding hip screw and the intramedullary hip screw for the treatment of unstable intertrochanteric fractures in the elderly . One hundred and two patients were r and omised on admission to two treatment groups . Fifty-two patients were treated with a compression hip screw ( CHS ) , and fifty had intramedullary fixation with an intramedullary hip screw ( IMHS ) . Patients were followed for 1 year and had a clinical and radiological review at 3 , 6 and 12 months . The mean duration of operation and fluoroscopy screening time was significantly greater for insertion of the intramedullary hip screw . There was no difference between the groups with regard to transfusion requirements or time to mobilise after surgery . There were two technical complications in the CHS group and three in the IMHS group . There was no significant difference between the two groups in radiological or functional outcome at 12 months . It remains to be shown whether the theoretical advantages of intramedullary fixation of extracapsular hip fractures bring a significant improvement in eventual outcome
