Abstract :

Background: 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 analyse the results of treatment of fracture neck of femur with cannulated cancellous screw fixation using BDSF method. Methods: 15 patients with intra capsular neck of femur fracture fixed by BDSF method were followed up for a period of two years post–surgery and their functional outcome was assessed based upon Harris hip scoring system. Results: According to Harris hip scoring system, we had excellent results in 60% cases, good in 20% cases and poor in 20%. Conclusions: Management of intracapsular fracture neck of femur with cannulated cancellous screw fixation using BDSF is a very good method of treatment being a surgically easy procedure. The position of the screws allow them to slide under stress with a minimal risk of displacement. The position of the distal most screw, Primary Trabecular Screw(PTS) is in line with the primary compressive trabeculae which allows the body weight to be transferred successfully from the head fragment onto the diaphysis. Compared with conventional cancellous screw fixation, the screws are purchased in the thick diaphyseal cortex and are placed in two different planes wide apart from each other which adds to the stability. This prevents screw loosening and varus collapse. The method was developed in search of a solution for those patients, for whom primary arthroplasty is contraindicated
