Abstract :
Background: Abnormal narrowing of the lumbar spinal central canal, lateral recess, foramen and extra foraminal space is called lumbar spinal canal stenosis. Patients present with low back pain with or without radiculopathy and neurological claudication and may need surgical intervention, if conservative treatment fails. Lumbar laminoplasty and decompressive laminectomy are few of the surgical intervention techniques.
Objectives: To evaluate and compare the functional outcome of lumbar laminoplasty and decompressive laminectomy for patients with multilevel lumbar spinal canal stenosis.
Methods: 60 consecutive patients underwent lumbar laminoplasty and decompressive laminectomy in BSMMU from September 2017 to March 2020. The patients were randomized into two groups: one group for lumbar laminoplasty and another group for decompressive laminectomy. Two patients from each group were dropped out at final follow up. Remaining patients were followed up for 12 months. Outcome were measured by VAS, JOA, ODI score and Modified Macnab criteria. All the data were compiled and sorted properly and the quantitative data was analyzed statistically by using Statistical Package for Social Science (SPSS-22). The results were expressed as percentage and mean ± SD and p
