Aim: To analyse the outcome measurement in lumber degenerative disc disease after single level microdisectomy using oswestry disability index. Material & Methods: This “prospective observational study” was carried out at “the Kalinga Institute of Medical Science in Bhubaneshwar” among 120 hospitalised patients with lumbar degenerative disease. Complete examination was done along with MRI, Oswestry Disability Index, & VAS scale for before & after surgery. For statistical analysis, the means & standard deviations of each group's measurements were employed using SPSS 22.00 for Windows; SPSS Inc., Chicago, USA. Results: The majority of individuals (58.33%) belonged to the age group of above 60. Preoperative deficits in motor function & sensory perception were seen in 64.17% & 71.67% of the participants, respectively. The study subjects' preoperative ODI score was 34.19, & on the first postoperative day, it had dropped to 23.36. The mean ODI score after 30 days after procedure was 12.74. As a result, the ODI score significantly improved (p<0.05). Prior to surgery, the mean VAS (leg & back pain) was lower than 30 days post-op; this difference was shown to be statistically significant at p<0.05. Conclusion: In summary, our research indicates that a minimally invasive strategy for treating LDH typically yields a good postoperative long-term result. Based on our research, there may be a difference in the long run, as indicated by the ODI score.
