Sometimes, a child’s arm or leg does not form or grow properly in the womb, and the child is born with a malformed limb. This is called a congenital limb defect.
Causes of Congenital Limb Defects
We don’t know the exact causes of congenital limb defects; however, the chance of a congenital limb defect occurring increases when:
- There are genetic abnormalities
- The baby’s growth is restricted
- The baby or mother is exposed to certain chemicals, medicines, or viruses
- The mother smokes tobacco during the pregnancy
Symptoms
A child with a congenital limb defect may have:
- An arm or leg that is smaller or larger than normal
- Failure of the fingers or toes to separate
- Extra or missing fingers or toes
- Lack of an arm or leg
