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 .
Pertrochanteric Fractures: Is There an Advantage to an Intramedullary Nail?: A Randomized, Prospective Study of 206 Patients Comparing the Dynamic Hip Screw and Proximal Femoral Nail
Objectives To compare the results between a sliding compression hip screw and an intramedullary nail in the treatment of pertrochanteric fractures . Design Prospect i ve computer-generated r and omization of 206 patients into two study groups : those treated by sliding compression hip screw ( Group 1;n = 106 ) and those treated by intramedullary nailing ( Group 2;n = 100 ) . Setting University Level I trauma center . Patients All patients over the age of fifty-five years presenting with fractures of the trochanteric region caused by a low-energy injury , classified as AO/OTA Type 31-A1 and A2 . Intervention Treatment with a sliding compression hip screw ( Dynamic Hip Screw ; Synthes-Stratec , Oberdorf , Switzerl and ) or an intramedullary nail ( Proximal Femoral Nail ; Synthes-Stratec , Oberdorf , Switzerl and ) . Main Outcome Measurements Intraoperative : operative and fluoroscopy times , the difficulty of the operation , intraoperative complications , and blood loss . Radiologic : fracture healing and failure of fixation . Clinical : pain , social functioning score , and mobility score . Results The minimum follow-up was one year . We did not find any statistically significant difference , intraoperatively , radiologically , or clinical ly , between the two groups of patients . Conclusions There is no advantage to an intramedullary nail versus a sliding compression hip screw for low-energy pertrochanteric fractures AO/OTA 31-A1 and A2 , specifically with its increased cost and lack of evidence to show decreased complications or improved patient outcome
