Diffuse idiopathic skeletal hyperostosis: A potential factor in the induction of thoracic spondylotic myelopathy.

Background: Thoracic spondylotic myelopathy (TSM) commonly occurs at the thoracolumbar junction, and mechanical stress is thought to be involved. In DISH, the anterior longitudinal ligament becomes ossified. Although DISH is suspected to be involved in TSM pathology, reports are limited.
