A case of invertebral disc degeneration and prolapse with Schmorl's node formation in a sheep

摘要

A Schmorl's node is the herniation of nucleus pulposus through the cartilaginous end plate of the vertebral disc into the body of the adjacent vertebra. Their formation is relatively common in people, and they may be symptomatic or asymptomatic. In contrast, there are few reported cases of Schmorl's nodes in non-human animals. This report describes a case of thoracic intervertebral disc degeneration, with Schmorl's node formation in a sheep.
