What are congenital hand deformities?
Congenital hand deformities are differences in the shape or structure of the hand that are present at birth. These conditions can affect the fingers, thumb, bones, muscles, tendons, or skin.
Some hand differences are mild and affect appearance more than function. Others may make it harder for a child to grasp, hold, or move objects as they grow and develop.
These conditions happen when the hand does not develop typically during pregnancy. In some cases, congenital hand deformities are linked to inherited conditions or genetic changes. Other times, the exact cause is unknown.
Symptoms
The appearance and severity of congenital hand deformities can vary widely from child to child.
Common examples include:
- Missing fingers or thumbs
- Fused fingers
- Extra fingers
- Small or underdeveloped fingers
- Curved or stiff fingers
- Enlarged fingers
- Limited movement or grip strength
How is it diagnosed?
Many congenital hand deformities are identified at birth during a physical exam. Providers evaluate the appearance, movement, and function of the hand and fingers.
Imaging tests such as X-rays may be used to look at the bones and joints more closely. Children are often evaluated by specialists with experience in pediatric hand conditions to help guide treatment planning.
How is it treated?
Treatment depends on the type of hand difference and how much it affects movement and daily activities. Early care can help support normal growth and hand function.
Treatment options may include:
- Stretching and splinting
- Physical or occupational therapy
- Reconstructive surgery
- Surgery to separate fused fingers
- Removal of extra fingers
- Tendon or bone procedures to improve movement
- Prosthetic devices when needed
Some children may need more than one procedure as they grow. Therapy and follow-up care are often important parts of long-term treatment and recovery.
