Cauda Equina Syndrome (CES)

What is Cauda Equina Syndrome?

Cauda Equina Syndrome (CES) is caused by compression of the nerve roots passing from the lower back toward the tail at the level of the lumbosacral junction. The most common cause of cauda equina syndrome is narrowing of the vertebral canal at the level of the lumbosacral joint (called lumbosacral stenosis).

Lumbosacral stenosis is most commonly caused by degenerative changes to the intervertebral disc, arthritis of the joints, and abnormal proliferation of the ligaments. Dogs with abnormal shape to their last lumbar or sacral vertebrae and german shepherd dogs are predisposed to developing lumbosacral stenosis. Neoplasia (cancer) and infection at the level of the lumbosacral disc (discospondylitis) may also cause signs of cauda equina syndrome.
