Background: The term disc prolapse is defined as extrusion of nucleus pulposus through a rent in annulus fibrosus. This prolapse disc causes impairment of function by nerve root compression compelling the patient to seek medical advice for low backache. A lumbar herniated disc is a common cause of low back pain radiating to the leg. The problem of prolapsed intervertebral disc is of great importance in this part of the world, because of the fact that people are subjected to various physical stress due to their living habits, low socioeconomic status. Ninety percent of lumbar disc extrusions occur at L4- L5or L5-S1. Central lesion may cause no symptoms with the exiting nerve roots unaffected whereas paracentral lesions cause symptoms due to compression of the exiting nerve root. Radio imaging technique has a pivotal role in the diagnosis of vertebral disc herniation. Various radiological procedures are used for the diagnosis, but MRI which is a relatively newer technique is treated as the gold standard in the field. Aim of the Study: In the present study, an attempt is made to establish the anatomy of herniated lumbar disc by the help of MRI technique in the patients of Eastern India & to correlate the occurance of disc herniation with age, sex & vertebral level. Methods and Material: The present study included 120 patients who have lumbar disc herniation syndrome & their MRI findingd are compared with MRI findings of 80 normal persons who are used as control. Results and Conclusions: The different parameters are compared & observed that the maximum number of disc prolapse occurs between 31- 40 age group. Taking the vertebral level into consideration, it is seen maximum number of herniation occurs at the level of L4- L5.
