Abstract
Recently we experienced 4 patients with hard scoliosis, 3 cases were herniated lumbar intervertebral disc, one lumbar spinal canal stenosis. We analysed these patients.
Results
1. The patients inclined their trunks foreward with the slight flexion of knee joint on the side of sciatica.
So, the center line of body gravity was transferred foreward and lumbar lordosis was decreased. We considered this posture were decompression of posterior element of lumpar spine.
2. As the lateral curvature on the trouble side was established rapidly, the center line of body gravity was transferred toward the opposite side.
3. Radical treatment for sciatica was the only corrective method for hard scoliosis.
4. In all cases, convex side of primary lumbar curves were bile on the trouble side, the numbers of the affected intervertebral spaces were multiple, the lowest level was the 4th lumbar intervertebral space, and all of them were muscular type and male.
We couldn't confirm any regularity for the relation between the convex side of the lumbar scoliosis and the position of stimulus to the nerve root.
