Background:Lumbar spine is the primary weight bearing column with altered posture it puts pressure on these intervertebral discs and it can lead to weak core muscles eventually leading to altered lumbo-pelvic angle and that might result in disc prolapse. AIM: To find correlation between lumbar spine posture and disc prolapse using radiographic analysis. Methods: Study design was Co-relational study and sampling method was Random sampling, Samples were taken from Radiology Department at Dr D Y Patil Medical college and research center, Pimpri. Outcome measure taken was Cob’s angle. Procedure: Ethical permission was obtained from the institutional sub-ethics committee. MRI from Radiology department were reviewed. The Cob’s angle / lumbar lordosis was calculated using the available film records, and correlated with incidence of disc prolapse.
