Call your health care provider if you have any concerns about limb length or appearance.

What to expect at your health care provider's office:

An infant with limb abnormalities generally has other symptoms and signs that, when taken together, define a specific syndrome or condition or give a clue as to the cause of the abnormality. Diagnosis of that condition is based on a family history, medical history, and thorough physical evaluation.

Medical history questions may include:

• Does anyone in your family have skeletal abnormalities?
• Were there any problems during pregnancy?
• What drugs or medications were taken during the pregnancy?
• What other symptoms or abnormalities are present?

Laboratory studies such as chromosome studies, enzyme assays, x-rays, and metabolic studies may be done to confirm a suspected disorder.
