ABSTRACT

Objective: In this study our main goal is to evaluate efficiency of lumbar decompression, Interbody Fusion and Posterior instrumentation method in the treatment of Spondylolisthesis. Method: This prospective Interventional study was carried out at from July 2017 to June 2019 (24 months) at Department of Orthopedics Surgery, DMCH, Dhaka. All patients with clinical and radiological evidence of Spondylolisthesis. Total 18 patients were selected, among them 11 female and 7 males. Results: During the study, in this study fusion occurred in 16(88.9%) and probably not fusion occurred 2(11.1%) radiological after 6 months. Mean preoperative VAS 6.83±0.49and postoperative VAS 2.27±0.57. Mean difference preoperative to postoperative VAS score were statistically significant. According to preoperative and postoperative VAS score for leg pain, mean preoperative VAS 6.75±0.60and postoperative VAS 1.28±0.46. Mean difference preoperative to postoperative VAS score were statistically significant. Regarding the modified Macnab criteria of the study patients, 14(78.0%) was found excellent in final follow up and only 4(22.0%) found good. Conclusion: To conclude, Posterior Lumbosacral Interbody fusion method is effective in relieving symptoms, achieving stability and fusion and lesser complication rates in surgical management of Spondylolisthesis.
