The authors studied the natural evaluation of lumbar soft disc herniation in 20 patients with lumbar radiculopathy that was successfully treated with conservative theraphy only. The first computed tomography (CT) examination was performed during the acute phase of the radiculopathy, and the second performed from 3 to 24 months after healing. The initial CT allowed classification of the herniations according to size: ten were considered small. ten medium. Comparison with follow-up scans showed that 18 of Herniations decreased between 0 and 25%, two decreased between 75 and 100%.
