Background: Lumbar intervertebral disc herniation is a common health problem in our country. Majority of the surgeries of the spine are done due to disc herniation in Bangladesh. Discectomy can be limited to partial discectomy where only extruded and sequestrated portion is removed, subtotal discectomy where the whole of nucleus pulpous is removed and total discectomy where the entire intervertebral disc of the affected level is removed. Aim of the study: To find out the effectiveness and functional outcome of fenestration and discectomy by mini-incision for the prolapsed lumbar intervertebral disc in our context. Material & Methods: This prospective observational study was conducted at National Institute of Traumatology and Orthopaedic Rehabilitation (NITOR), Dhaka, Bangladesh during July 2015 to June 2017. A total of 31 patients with prolapsed lumbar intervertebral disc were included for the study according to inclusion and exclusion criteria. Results: The mean age was 35.98 ± 8.50 years with the range from 17 to 50 years. In this study, the most common muscle weakness in EHL. Out of 31 patients, 22 (70.96 %) patients were in this group. 08 (25.80%) cases had weakness in FHL and another group 01 (3.22%) had both muscle weakness. Out of 31 patients, 30 (96.78%) patients had preoperative sensory deficit and 03 (09.67%) patients had postoperative sensory deficit, which is statistically significant. In preoperative period, moderate pain in 27 (83.87%) patients, severe pain in 04 (12.90%) patients. In postoperative period had no pain in 22 (70.96%) patients, mild pain was noted in 08 (25.08%) patients, moderate pain in 01 (03.22%) patient. 20 (64.51%) patients had para spinal muscle spasm in the preoperative period, whereas no patient had any spasm in 3 months postoperatively. The success rate was 100% and the result was statistically significant. In this present series, functional outcome was assessed according to Macnab criteria. 08 (25.80%) cases were excellent, ...
