Hemivertebrae is a congenital abnormality of the spine which often affects brachiocephalic breeds, such as the English Bulldog, French Bulldog, Pug and Boston Terriers. The vertebrae become deformed, either by fusing or becoming wedge-shaped, which can cause a twisting of the spine. The deformity in the vertebrae can cause compression of the spinal cord sometimes leading to weakness of the hind limbs. Fortunately, many dogs with this condition do not exhibit any clinical signs or pain, and do not need to be treated. Rest and anti-inflammatories can be helpful for affected dogs. Only in the more severe cases would surgery be considered as necessary to relieve compression on the spinal cord.
