Abstract
We analyzed 77 patients with lumbosacral radiculopathy on the basis of electromyography and radiologic study including CT scan and myelography. The results were as followings: 1. In the 62 male and 15 female subjects with a mean age of 39.3 years. The peak incidence was between ages 20 and 40 years (64%). 2. The causes of lumbosacral radiculopathy were herniated lumbosacral intervertebral disc (78%), lumbar strain (9%), fracture of lumbar vertebra (6%), spinal cord tumor (4%), spinal stenosis(3%) in order. 3. Most common involving site was L5 root on EMG and L4-5 intervertabral disc space on radiological study. 4. The prognosis of the patients with normal EMG finding was better than that of the patients with abnormal EMG finding(p<0.05). 5. There was no significant difference between the prognosis of the patients with abnormal radiologic finding and that of the patients with normal radiologic finding.
