Objectives: Lower back ache is one of the most important problems worldwide. It is important to consider that low back pain is becoming the most prevalent musculoskeletal disorder in the modern world, having a significant impact on healthcare expenditures and being a major cause of disability. Aim: The purpose of this study was to ascertain the postoperative results of discectomy and fenestration in individuals suffering from lumbar intervertebral disk prolapse. Materials and methods: This prospective study was carried out on patients admitted to the tertiary care hospital who had lumbar intervertebral disk prolapse. The visual analog scale (VAS) and Oswestry disability index (ODI) scores were used to assess the patients. Those patients who were not improving with conservative care have been examined and operated on with a lumbar fenestration discectomy procedure. Results: Among 40 participants, the average age-group was 45.9 years with a male predominance. The common level of disk prolapse was found to be at the level of L4-L5 disk. The most common symptom reported by the participants was sciatica. Out of 40 participants, 87.5% (n = 35) had good outcome, 10% (n = 4) had a fair outcome, and 2.5% (n = 1) had a poor outcome. Conclusion: Our study found that more than three-fourths of the participants had good functional outcomes and very minimal postoperative complications. The causes for delayed functional recovery were high body mass index, extremes of age, and a heavy worker population. Therefore, fenestration and discectomy procedures are the gold standard for the Indian population, unlike the recent advanced techniques like endoscopic and tubular discectomy.
