Effectiveness of percutaneous key lesion endoscopic lumbar decompression for the treatment of lumbar spinal stenosis in octogenarian patients.

Abstract

IntroductionWith increasing life expectancy, degenerative lumbar spinal stenosis (LSS) has become a common problem in the geriatric population. LSS reduces the quality of life, limits daily activities, and requires therapeutic aids. We share our experiences of treating octogenarian patients with LSS with key lesion percutaneous single portal endoscopic unilateral laminotomy and bilateral decompression (sEndo-ULBD).Materials and methodsNine octogenarian patients who underwent sEndo-ULBD between January 2021 and July 2022 were prospectively enrolled in this study. Their visual analogue score (VAS), Oswestry Disability Index (ODI), disc height, spondylolisthesis, lumbar lordotic angle, lumbar scoliotic angle, and spinal canal area before and after sEndo-ULBD were followed up for more than six months.ResultsThe VAS score was significantly reduced three months after the operation (p ConclusionsKey lesion sEndo-ULBD was an appropriate, safe, and effective treatment for octogenarian patients suffering from degenerative LSS. With an average follow-up of over one year, we did not find any significant progression in spinal curvature or instability. sEndo-ULBD is an ideal alternative to aggressive fusion fixation lumbar surgery for managing degenerative LSS in octogenarian patients with functional disability.
