[Comparative pathology of vertebral hyperostosis].
The changes seen in vertebral hyperostosis are due to a slow ossification of the perivertebral connective tissue causing osteophytic spurs and/or bridging of intervertebral ankylosis. The same changes seen in man are also seen in all land and aquatic mammals. This confrontation of comparative pathology emphasizes certain essential points in common. There is a relation between the vertebral hyperostosis and local anatomic and physiologic conditions linked to a ligament insertions. It occurs in bipodisis or tetrapodisis as well as in an aquatic environment. It must be distinguished from an osteoarthritic intervertebral remodeling and the evolution of its bone tissue is dissociated from that of the adjacent vertebral bone tissue. It is frequently observed in relation to general conditions (aging -- diabetes in man -- dietary imbalance in the animal). This example emphasizes the interest that comparative pathology can have for the rheumatologist.
