ABSTRACT
Background: Degenerative lumbar spinal stenosis (DLSS) is a condition
where degenerative and arthritic state of the disc and facet joints
respectively results in the displacement of the vertebra resulting in lower
back pain in association with radiculopathy. In patients with degenerative
lumbar spine, the rate of fixation has increased.
Aim: To identify the difference in outcome of decompression
alone versus decompression with spinal fixation in DLSS.
Place and duration
of study: Department of Orthopaedic & Spine
Surgery, Ghurki Trust Teaching Hospital, Lahore from 1st January
2017 to 31st December 2019.
Methodology: All the discharged patients with primary diagnosis of
DLSS were identified. Two subgroups were studied i.e. Decompression only and
Decompression with TranspedicularScrew Fixation .Primary outcome among patients
was assessed using Swiss Spinal Stenosis Score (SSS). All the data were entered
and analyzed using SPSS software and p-value≤0.05 considered to be significant.
Results: Total number of patients included in study was 87.out of
the total,34(39%) patients had underwent decompression alone, whereas in
53(60.9%) patients decompression with transpedicular fixation were done.
Significant difference was not observed among cases with respect to mean score
on SSS based on two different types of surgical interventions. In decompression
with fixation group, the average length of stay of patients in hospital was 6.4
days as compared to decompression only group as 4.4 days.
Conclusion: Both surgical procedures decompression plus
transpedicular fixation and decompression alone produce similar outcome at 2
years follow-up.
