[Syndrome of femorolumbar extension rigidity].

Under observation there were 43 patients aged 10 to 22 years and showing the syndrome of femorolumbar extension rigidity. On surgical verification it was found that 5 pateints had productive epiduritis, 20 protrusions and prolapses of the discs complicated with productive epiduritis in the lumbar division of the vertebral column; 11 had tumours in the lumbar, 3 in the thoracic, 3 in the cervical divisions of the vertebral column. The syndrome was frequently accompanied by dysplasia of the lumbar division. This syndrome is similar to meningeal contractures; it manifests in reflectory disturbances of the extensor tone, and can be classed with traction syndromes. An adequate treatment method consists in surgical mobilization of the spinal cord, its radicles, and the dural sac.
