CERVICAL vertebral stenotic myelopathy (CVSM) is a common cause of spinal ataxia and paresis in horses that results from stenosis of the cervical vertebral canal and static or dynamic compression of the spinal cord ( Nout and Reed 2003). The disease is seen commonly in young, rapidly growing horses. Certain breeds, including thoroughbreds, appear predisposed to the condition, and male horses are at increased risk ( Mayhew and others 1993, Levine and others 2008).
