Subtrochanteric Valgus Osteotomy of Non-United Fracture Neck Femur by Dynamic Hip Screw
Background: Non-union and avascular necrosis of the femoral head is the main complications of fractures of the femoral neck. Valgization osteotomy is a therapeutic option that is considered to be effective for treating consolidation failure of transtrochanteric fractures. Hence; the present study was undertaken for assessing efficacy of Subtrochanteric Valgus Osteotomy of Non-United Fracture Neck Femur by Dynamic Hip Screw.
Methods: A total of 20 patients with non-united fracture of femur neck were enrolled. Complete demographic details of all the patients were obtained. All the patients underwent Subtrochanteric Valgus Osteotomy under the hands of skilled and experienced orthopaedic surgeons. Pre-operative assessment of all the patients was done (both clinical and radiographic). Post-operative follow-up was done and outcome was evaluated by using Harris hip screw and change in neck shaft angle. All the results were recorded in Microsoft excel sheet and were analysed by SPSS software.
Results: Mean duration of surgery was found to be 69.2 minutes. Mean blood loss was found to be 380.5 ml. Mean time for fracture union was found to be 11.2 weeks. Mean preoperative neck shaft angle was 102.1° and it improved significantly after treatment reaching a postoperative value of 137.9°. Mean preoperative Harris hip score was 42.8 and it improved significantly after treatment reaching a postoperative value of 88.4.
Conclusions: Subtrochanteric Valgus Osteotomy by Dynamic Hip Screw for non-United Fracture Neck Femur provides adequate results with excellent prognosis. However; further studies were recommended.
