Abstract

Background: Osteosynthesis of femoral neck fractures is related up to 46% rate of complications. This study aimed to evaluate clinical, radiological and functional outcome of Biplane Double supported screw Fixation (BDSF) in femoral neck fractures. Methods: This prospective case series study included 20 patients with recent femoral neck fractures. All studied cases were subjected to history, examination, X-ray views (AP and lateral views) hip was obtained. Results: Out of the total 20 cases included in the study, 45% of the cases were followed up for 2-4 months after surgery. The average time lapse before surgery was 26 h (range 6-36h). Nineteen patients were united within 6 months after the operation. 85% without complications, 15% with complications. According to Harris score, Final results were considered: excellent in 7 (35 %) patients. Good in 10 (50%) patients. Fair in 1 (5%) patient. Poor in 2 (10%) patients. RUSH score was with median (IQR) of 23 (16.5-25). Conclusion: This new method of fixation of femoral neck fractures using Biplane double-supported screw fixation [filipov method} enhance femoral neck fracture fixation strength, reveals excellent clinical outcome and is a vaild alternative to other fixation methods. Provides satisfactory results in 85% of cases and unsatisfactory results in 15% of cases. Early intervention within 24h, anatomical reduction, cortical screw support and intraoperative impaction are the most important steps. This method provides union rate of 95% without incidence of femoral neck shortening or failure of fixation.
