To study the outcome of micro decompression by unilateral laminotomy in lumbar canal stenosis
Journal Title: International Journal of Orthopaedics Sciences - Year 2017, Vol 3, Issue 2
Abstract
Introduction: Lumbar Canal Stenosis is developmental or congenital narrowing of the spinal canal that produces compression of the neural elements before their exit from the neural foramen. The narrowing may be limited to a single motion segment or it may be more diffuse spanning two motion segments or more. The spinal canal demonstrates narrowing, attributed most frequently to acquired degenerative or arthritic changes such as hypertrophy of the articulations surrounding the canal, intervertebral disc herniation or bulges, hypertrophy of the ligamentum flavum, osteophytes formation and degenerative spondylolisthesis. The classic presentation of Lumbar Canal Stenosis is neurogenic claudication. Aims and Objectives: To study the outcome of microdecompression by unilateral laminotomy in lumbar canal stenosis Methodology: This is institutional based prospective study of 36 patients, aged 20 to 80 years, with diagnosed lumbar canal stenosis treated with bilateral microdecompression of lumbar canal stenosis by unilateral laminotomy using microscope, surgical magnifying loops and microsurgery tools at Dr. Shankarrao Chavan Govt. Medical College Vishnupuri, Nanded. Statistical analysis done by chi-square test. Result: There was an rapid decrease in the leg pain scores from 8.94 In the pre-operative period to 1.36(SD±1.13) one month after operation. At 1 month follow up patients with no pain (VAS + 0) were 9 (25.00%). Conclusion: Unilateral laminotomy with bilateral micro decompression method is one of the excellent method for decompression of lumbar canal stenosis with early functional outcome as unilateral laminotomy preserves posterior midline structures with sparing of spinous process, opposite side lamina and paraspinal muscles.
