摘要：Background: Lumbar spinal stenosis (LSS), a disease that mainly affects people over 50 years old, may have a dramatic presentation with pain, difficulty in walking, changes in urinary functions in addition to root symptoms, such as numbness, burning, and feeling of heaviness in the legs. The treatment is very varied with several non-surgical and surgical possibilities. With an aging population, this disease becomes increasingly preoccupant for their uncertain evolution and without a well-defined correlation with imaging tests, treatment, and outcome may be troublesome. Moreover, LSS frequently affects patients who have associated comorbidity that can hinder the treatment. Objectives: To assess the outcome and short term results of MLL in treatment of patients with degenerative LSS. Patients and Methods: A prospective study, carried out at the Spine unite, Orthopedic department, Zagazig university hospitals from October 2018 to May 2020. Study was conducted on 12 patients diagnosed with LSS clinically and radiologically. Surgical technique involved minimal window resection of both laminae and ligamentumflavum of selected level with preservation of ligamentous structures and facet joints. Pain and disability were measured preoperatively and 6 months postoperatively with a visual analogue scale (VAS) and the Oswestry Disability Index (ODI). Results: VAS of leg pain improved from 8.16±0.71 to 1.20±0.41 showing 84.5 % improvement, while VAS of the back pain improved from 4.33±1.07 to 1.75±0.62 showing 59.5 % improvement. The ODI improved from 79.25±12.16 to be 6.78±2.98 showing 91.1% improvement. The mean anteroposteriorthecal diameter improved from 6.54±1.2 mm to 12.79±1.6 mm with 95.6% improvement, while the mean DSCSA improved from 60.34±6.8 mm2 to 110.65±4.82 mm2 showing 83.3% improvement at the last follow up (6 months). Conclusion: We concluded that MLL is a good, safe, effective, minimally invasive approach and easily applied surgical option for treating degenerative LSS.
