Materials and Methods: This is a prospective observational study was conducted for two years at Dhaka Medical College Hospital, Dhaka between July 2016 to June 2018 with total number of twenty of prolapsed lumbar intervertebral disc (PLID) patients who underwent lumbar decompression by laminotomy and discectomy. Regular follow up was done for each patients at least 6 months after operation to assess the functional outcome by Macnab criteria, VAS and ODI. Results: The mean±SD age was 42.59±8.17 years, range 32-60 years, 79% male and 21% female patients. Maximum number of 48% of patients were in the age group between of 31 to 40 years.
