| Abstract | ||
| Background: Degenerative lumbar spinal stenosis (LSS) remains one of the most common indications for lumbar spine surgery in elderly patients. Aim of the study: to assess the results of a minimally invasive bilateral decompression surgery with a unilateral laminectomy (ULBD). Patients and methods: an upcoming clinical trial investigation was conducted at the Neurosurgery Department of Zagazig University hospital during the period from November 2021 to August 2022. 24 patients were included in our study. Demographic, Clinical outcomes were assessed, both before and after surgery, The Visual Analogue Scale was used to rate leg and low back discomfort (VAS). Before and after surgery, disability was assessed using the Oswestry Disability Index (ODI) 3 months postoperatively. Pre- and postoperative measurements of the size of the spinal canal and the approximate cross-sectional area (CSA) of the dural sac were made. Results: VAS for low back pain (LBP) improved from 6.83 ± 2.65 to 1.79 ± 0.70, while VAS for leg pain improved from 6.54 ± 3.04 to 1.87 ± 0.59. ODI significantly decreased from 57 ± 6.75 % to 18.58 ± 5.01 %. A-P diameter increased from 9.12 ± 0.46 to 13.60 ± 0.61 mm, while. ADSCSA of the stenotic levels increased from 90.67 ± 4.32 to 167.37 ± 26.74 mm2. Conclusion: ULBD techniques is effective and safe procedure for LSS treatment, with good postoperative outcome. | ||
