Dislocated lumbar vertebral epiphysis in adolescent children

Abstract

✓ Three teenagers operated on for suspected rupture of a lumbar intervertebral disc are presented. The finding at surgery in each case was a bony, cartilaginous, and nucleus pulposus ridge crossing the anterior spinal canal. Since the bony epiphyseal ring or apophysis is said to be deficient posteriorly, these patients presumably had a dislocation of an anomalous epiphyseal ring.
