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.
The aim of this study is to evaluate the outcome of transpedicular screw fixation with fusion when
added to posterior decompression in patients with degenerative lower lumbar canal stenosis
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 followup.
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
