Biplane double supported screw fixation in femoral neck fractures using percutaneous approach

Introduction: Fracture neck of femur has always presented a great challenge to the Orthopaedic surgeons. Results depend upon adequacy of reduction and stable fixation. Fixation with cannulated cancellous screws is usually adequate for femoral neck fractures. The aim of the study was to analyze the results of treatment of fracture neck of femur with cannulated cancellous screw fixation using BDSF method.Materials and Methods: This prospective study was carried out in the postgraduate Department of Orthopaedics, Govt. Bone and Joint Hospital, an associated hospital of Govt. Medical College Srinagar from 2019-2021. A total of 25 patients who presented in the department with femoral neck fractures and qualified the inclusion criteria were included in the study.Results: Among 25 patients 12 (48%) patients achieved excellent results, 8 (32%) patients achieved good results, 3 (12%) patients achieved fair results and 2 (8%) patients achieved poor results. 80% of the patients achieved either excellent or good result.Conclusion: BDSF is a novel method of fixation of femoral neck fractures, associated with higher axial fixation strength and union rate compared to conventional fixation methods. It employs bi-plane positioning of three cannulated screws placed at steeper angles to the diaphyseal axis.
