Abstract : Baboons were dropped vertically from four feet above the ground. The vertebral columns were examined with scanning electron microscopy and ligh microscopy six months and six years post-impaction. Lesions observed were separation of the cartilaginous end plate from the vertebral body and fragments of bone concentrated above the nucleus pulposus. The end plate separation appears to heal but the damage to the vertebral bodies in association with the nucleus pulposus may lead to disc narrowing and osteophytes some time subsequent to the impaction.
