“Outcome of Short Segment Fixation with Pedicle Screws, and Interlaminar Fusion with Autologous Bone Graft” (Published)
Background: Spondylolisthesis is a slip of all or part of a vertebra forward on another. Gravity and muscle action apply a caudal force on the lower lumbar vertebrae, which is counteracted by the superior and inferior facets, pedicles, posterior arch and intervertebral disc. Short segment fixation is an established technique for Spondylolisthesis of the lumbar spine. Objective: To assess the Outcome of Short Segment Fixation with Pedicle Screws, And Interlaminar Fusion with Autologous Bone Graft. Methods: The present case-control study was conducted in the Department of orthopedics, National Institute of Traumatology & Orthopaedic Rehabilitation (NITOR), Dhaka, Bangladesh over a period of one year between January 2019 to February 2020. 17 patients with Spondylolisthesis L4-L5 or L5- S1 were operated with short segment fixation with pedicle screws and interlaminar fusion with autologous bone graft. The follow up duration was for 6 months. Results: The mean percentage of slip improved from 29.4% preoperatively to 9.60% at 6 months. The mean Denis pain score and Denis work score improved from 3.95 and 3.95 preoperatively to 1.95 and 1.95 respectively at 6 months. At last follow up, superficial infection had occurred in 1 patient. There was no implant failure or neurological deterioration. Conclusion: Short segment fixation in spondylolisthesis using pedicle screws and interlaminar fusion with autologous bone grafting leads to improved clinical and radiological outcome in patients who have failed to get relieved by conservative therapy. The procedure leads to relief of pain and ability to resume previous work.
