MATERIAL and METHODS: Between 2002 and 2007, 1630 patients underwent surgery and a large disc herniation was the main problem in 59 patients (3.6%). We performed a retrospective analysis of the demographic data of these patients. Magnetic resonance (MR) images were evaluated according to the disc type and level. Variables were evaluated both at baseline and follow-up, with special emphasis on physical job characteristics, sports activities, and MR - based morphologic findings.

RESULTS: Central large disc herniation was diagnosed in 59 patients consisting of 41 males and 18 females. The average age was 34.7 years. 36 patients had a central mass prolapse that occupied more than 50% of the spinal canal. Intraoperative observations confirmed that 29 out of 36 central disc prolapse patients (80.5%) had intact posterior longitudinal ligaments. Interestingly, the condition in these 29 patients was found to have a direct relation with age and occupation or other body training sports activities.

CONCLUSION: The size of the large central disc herniation, physical activity, age and gender are major factors in the development of disc herniation. Keywords : Large lumbar disc herniation, Outcome, Physical Activity
