Abstract

Abstract
Background: Treatment of choice in degenerative lumbar canal stenosis (LCS) is laminectomy. Adding lumbar fusion to decompression is another option preferred by some surgeons to prevent possible instability after posterior elements removal
Methods: A prospective study where we evaluated 64 patients with degenerative lower LCS in Benha University Hospitals from January 2017 to January 2020, those underwent decompression of lower two levels L4-5 and L5-S1 with instrumented fusion of L4,5and S1 with 2-years follow-up. Pain changes evaluated using VAS score at 1- and 2-years post-operative and functional outcome at 1- and 2-years post-operative using Oswestry Disability Index (ODI) compared to preoperative scores
Results: Age of our patients ranged from 38 to 62 years with a mean 54.4 ±6.8 years and 42 patients were females (65.6%). VAS changes for low back pain and leg pain recorded at 1 and 2-years post-op. compared to preop. showed statistically significant improvement (P
