Common names or abbreviations:
 | Spina bifida |
Description or definition:
|
Spina bifida is a developmental abnormality where some vertebrae are malformed and do not fully cover the spinal cord, leaving it exposed to injury. The abnormalities can range in severity from slight malformation of only a small part of one vertebra – to absence of most of the vertebral arch on multiple vertebrae. Spina bifida can occur anywhere in the spinal column, but it is seen most often in the lower back region. This condition is congenital (present at birth), and both genetic and environmental factors (toxins, nutritional deficiencies during pregnancy) are thought to play a part in the development of this condition. |
Symptoms:
|
The symptoms depend on the severity of the condition. In mild cases, the dog may not have any observable medical problems at all. However, with more severe defects there will be clinical signs that are associated with the specific area of the spinal cord that is affected. Symptoms may vary from hind end weakness and lack of coordination to paralysis and urinary and fecal incontinence. With a very severe defect, signs are generally evident as soon as the puppy starts to walk. |
Diagnosis:
|
Radiographs (X-ray) or more advanced imaging techniques (MRI, CT, etc.). |
Treatment:
Surgery may be helpful for mildly affected animals. Dogs with hind end weakness may benefit from hind end support when standing and/or walking and/or special products to help the owner manage incontinence.
