Among the congenital vertebral anomalies, hemivertebrae are the most likely to cause neurologic problems. They are wedge shaped vertebrae, and therefore can cause an angle in the spine (such as kyphosis, scoliosis, and lordosis). The most common location is the midthoracic vertebrae, especially the eighth (T8). Neurologic signs result from severe angulation of the spine, narrowing of the spinal canal, instability of the spine, and luxation or fracture of the vertebrae. Signs include rear limb weakness or paralysis, urine or fecal incontinence, and spinal pain. Most cases of hemivertebrae have no or mild symptoms, so ttreatment is usually conservative. Severe cases may respond to surgical spinal cord decompression and vertebral stabilization. less
