What causes sacral agenesis?

How does sacral agenesis happen? The cause of sacral agenesis is unclear but it has a well-known association with diabetes in pregnancy. Mothers exposed to organic fat solvents, embryonal trauma, radiation, lithium salts, etc. may be at risk of having babies with sacral agenesis.

Can people with sacral agenesis get pregnant?

In literature, very little is known about pregnancy in patients with sacral agenesis and therefore on the appropriate way to counsel a patient with this condition who is trying to get pregnant (Greenwell et al., 2013). Although a case of pregnancy in a woman with sacral agenesis is mentioned in a book (J.

Is sacral agenesis hereditary?

No constant genetic or chromosomal disorders are associated with sacral agenesis, but isolated cases are described. Some anterior spinal defects appear to be inherited as an autosomal dominant trait (181).

Is Caudal Regression Syndrome a disability?

As Types III and IV of Caudal Regression Syndrome result in severe deformities and complications, these forms of the disorder are inherently disabling and therefore medically qualified for Social Security Disability (SSD) benefits.

Is sacral agenesis a form of spina bifida?

An increased incidence of sacral agenesis has been associated with maternal diabetes and with parents who have spina bifida or scoliosis. These nerves leading from the sacral spine deliver messages to and from the bowel, bladder and muscles of the lower limbs and provide and receive sensory feedback to the brain.

How is sacral agenesis diagnosed?

Sacral agenesis is a less severe variant of caudal regression syndrome and in the presence of normal amniotic fluid, the diagnosis can be made by demonstrating the termination of lumbar spine and small and abnormal lower extremities [6].

How common is sacral agenesis?

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. It occurs at a rate of approximately one per 60,000 live births.

Is a sacral dimple a birth defect?

A sacral dimple is a congenital condition, meaning it’s present at birth. There are no known causes.

Can people with caudal regression syndrome walk?

Cases with thoracal and upper lumbar involvement cannot walk and have to use the wheelchairs. Ambulation in the home may be possible for cases with middle lumbar level but the community ambulation is not possible. Functional ambulation may be possible for cases with lower lumbar level.

What part of the body is the sacral?

The sacral region (sacrum) is at the bottom of the spine and lies between the fifth segment of the lumbar spine (L5) and the coccyx (tailbone). The sacrum is a triangular-shaped bone and consists of five segments (S1-S5) that are fused together.

Are sacral dimples rare?

How common are sacral dimples? Roughly 3 to 8 percent of babies are born with a sacral dimple.
