Evaluation of Biplane Double Supported Screw Fixation of Femoral Neck Fracture: A Longitudinal Study at a Tertiary Health Care Center in Manipur

Background: Various treatment modalities for treating fracture neck of femur have been described. But complications like insufficient reduction, unstable fixation and avascular necrosis of head have been reported with almost all the fixation techniques. Objective: To evaluate and assess the clinical and functional outcomes of biplane double supported screw fixation for managing femoral neck fracture using Harris Hip Score. Materials and Methods: A hospital-based longitudinal study was taken up in the Department of Orthopaedics RIMS, Imphal, Manipur during the period Aug 2018-July 2020. All the patients admitted in RIMS hospital with fracture neck of femur medically fit for surgery during the study period were included except those who are not medically fit for surgery and not willing to participate. Under standard surgical precautions, biplane double supported screw fixation was performed with three cannulated screws. Patients were followed for a minimum of 06 months to assess the outcome using Harris Hip Score. Results: 47 patients could be followed up-to 06 months. There was no significant blood loss during the surgery. After 06 months of the surgery radiological union was seen in 39 (83%) patients. At the end of 03 months the Harris Hip Score was not that encouraging but at the end of 06 months 40% had excellent score, 36% good score, 13% fair score and the remaining 11% had bad score. The difference in the scores at 03 months and 06 months was found to be statistically significant. Conclusion: Management of femoral neck fracture with Biplane Double Supported Screw Fixation provides good clinical and functional outcomes. BDSF is a surgical technique which should be offered to the patients with fracture neck femur before contemplating total or hemi arthroplasty of hip.
