[Root compression in lumbar scoliosis--clinical picture and treatment based on 13 personal cases].

From 1971 to 1980 13 adults presented with lumbar scoliosis and radicular symptoms. The entrapment developed in nine cases on the concave side of the scoliosis, only in one case of severe degenerative hypertrophy of one apophyseal joint, on the convex side. Bilateral symptoms in two cases with scoliosis and stenosis as well, and in one case severe compression of cauda equina. Operation consisted of appropriate laminectomy, unroofing of the lateral recess and facetectomy in advanced cases. Results of operation were usually good, occasionally with improvement even of back pain.
