A to Z: Deformity, Congenital
May also be called: Birth Defect; Congenital Abnormality; Congenital Anomaly; Congenital Disorder; Congenital Defect
A congenital deformity is a change in the normal size or shape of a body part caused by a condition that a baby is born with.
More to Know
A deformity is any sort of disfigurement or distortion that makes a part of the body a different size or shape than it would be normally. Deformities can be:
- congenital: present at birth
- developmental: appearing later in childhood
- acquired: caused by injuries or illnesses that were not present at birth
Most congenital deformities are caused by abnormal genetic coding, but some can be due to infections or environmental factors — such as alcohol abuse — that affect the mother and fetus during pregnancy.
Congenital deformities can range from mild to severe. Mild deformities might not be visible or cause any symptoms. In severe cases, deformities can be readily apparent, cause pain, interfere with the movement and functioning of affected body parts, and negatively affect self-image.
Treatment depends on the specific deformity and often includes surgery or the use of corrective devices like back braces and leg casts.
Keep in Mind
Many congenital deformities can't be seen, won't cause any problems, and will never need treatment. Others respond very well to treatment, especially if it begins as soon as a doctor thinks a baby is ready for it. Cleft lips and palates, for example, can be corrected through surgery; and spinal deformities and clubfeet often can be successfully realigned through bracing and casting.
