A Comparative Study of Using Dynamic Hip Screw vs Multiple Cancellous Screw Fixation in Fracture Neck of Femur in Youngadults

Abstract

Introduction: Incidence of fracture of neck of femur is increasing in young adults. Dynamic Hip Screw with a derotation screw or CC screw is used in operation to reduce and stabilize femoral neck fractures. the commonest complications of intracapsular fractures of neck femur are non-union and avascular necrosis. Material And Methods: The study included 40 patients with history of trauma and diagnosed with fracture neck of femur. After thorough evaluation of patient , Pre-operative radiograph of pelvis with both hips were taken. Routine preoperative profile was done in each patient, along with pre-anesthetic check-up. Follow-up X-rays were taken at each follow-up, which were scheduled at 6 weeks, 3 months, 6 months and at 12 months. Functional and radiological outcome were assessed by scoring Modified Harris Hip Score Observation And Results At 12 months: The mean Harris Hip Score in Group 1 was 84.69 ± 4.51 and in Group 2 it was 90.68 ± 2.54. The mean Harris Hip score at 12 months was significantly higher in Group 2 as compared to Group 1 (P=0.001). Conclusion: When it came to treating fractures of the neck of the femur in young adults, our research found that dynamic hip screw fixation performed better than cancellous screw fixation. In terms of functional outcome, the dynamic hip screw had a higher Harris Hip Score and a lower rate of avascular necrosis. Based on the findings of this study, we recommend using a dynamic hip screw rather than a cancellous screw to fix a fracture of the neck of the femur. We recommend larger studies because there is a lack of research comparing these two fixation modalities.
