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, urinary or fecal incontinence, and spinal pain. [5] Most cases of hemivertebrae have no or mild symptoms, so treatment is usually ...
Occulta has no or only mild signs, which may include a hairy patch, dimple, dark spot or swelling on the back at the site of the gap in the spine. [5] [1] Meningocele typically causes mild problems, with a sac of fluid present at the gap in the spine. [1] Myelomeningocele, also known as open spina bifida, is the most severe form. [2]
Caudal regression syndrome, or sacral agenesis (or hypoplasia of the sacrum), is a rare birth defect. It is a congenital disorder in which the fetal development of the lower spine—the caudal partition of the spine—is abnormal. [1] It occurs at a rate of approximately one per 60,000 live births. [2]
Diastematomyelia is a "dysraphic state" of unknown embryonic origin, but is probably initiated by an accessory neurenteric canal (an additional embryonic spinal canal.).) This condition may be an isolated phenomenon or may be associated with other segmental anomalies of the vertebral bodies such as spina bifida, kyphoscoliosis, butterfly vertebra, hemivertebra and block vertebrae which are ...
Neural tube defects (NTDs) are a group of birth defects in which an opening in the spine or cranium remains from early in human development. In the third week of pregnancy called gastrulation, specialized cells on the dorsal side of the embryo begin to change shape and form the neural tube.
[2] [3] Causes of a primary CSF leak are those of trauma including from an accident or intentional injury, or arising from a medical intervention known as iatrogenic. A basilar skull fracture as a cause can give the sign of CSF leakage from the ear, nose or mouth. [4] A lumbar puncture can give the symptom of a post-dural-puncture headache.
There is a birth defect of the ear that is visible and relatively common around the world. It is called preauricular sinus which, according to the U.S. National Institutes of Health, or NIH ...
Changes in the spinal bones in the neck may also increase the risk of spinal cord damage. Other skeletal signs include flattened vertebrae (platyspondyly), a hip joint deformity in which the upper leg bones turn inward , and an inward- and downward-turning foot (called clubfoot). Decreased joint mobility and arthritis often develop early in life.
