21 Aug Congenital Hand Disorders

Congenital hand disorders can make life challenging. They range from subtle like short or stiff fingers to dramatic, like a missing arm.

This guide provides a comprehensive overview of congenital hand differences, detailing common types, available treatment options, and practical ways to support a child’s development.

What are congenital hand disorders? 

Congenital hand disorders may start early in pregnancy, when arms, followed by hands, and then fingers, develop. When this process is interrupted, or a genetic syndrome or environmental problem interferes with it, a congenital hand condition results. Sometimes problems with the hands or upper extremities develop after birth, because of trauma or illness. Sometimes fingers and hands develop differently for no apparent reason.

Among the most common of these birth defects are: 

• A hand or arm that doesn’t fully develop in pregnancy.
• Failure of parts of the hand to separate during pregnancy, resulting in hands and fingers or bones that are fused together.
• Extra or missing fingers.
• Fingers of unusual size, either larger or smaller.
• Constriction band syndrome, in which a band of tissue forms around part of the hand or finger and constricts blood flow, growth and movement.

What other conditions can cause hand and arm disorders? 

Diagnosis is based on physical examination, imaging, and observation. The way this information is obtained varies, depending on a patient’s age.

Prenatal diagnosis: Some congenital problems are identified using prenatal ultrasound, allowing treatment planning to begin before birth. A prenatal consultation can be helpful in establishing a care plan and giving parents an idea of what life may be like when the baby is born.

Diagnosis in infancy: Some conditions don’t become apparent until later in infancy, when parents observe that a baby isn’t using hands or arms in typical ways. Toys can be a helpful way to engage babies in play to see how the hands are (and are not) used. Watching them interact with big toys, little toys and blocks can assist in ascertaining patterns of use for their hands, identifying the problem and determining how to make them more functional. Conversations with parents, a physical exam and imaging tests provide further information to make a diagnosis.

How are congenital hand disorders treated? 

From physical therapy to prosthetic devices, and splints to surgery, there are many ways to help children with congenital hand and upper extremity conditions. Many children will not need an intervention to improve function. 

What surgical procedures are used to treat congenital hand conditions? 

Surgical treatment is always individualized to the needs of a particular patient, taking into account personal priorities regarding function and appearance.

What surgical procedures are used to treat other types of hand and arm disorders?

• Microsurgery
• Digit replacements
• Treatment for traumatic injuries to the hands and arms

What is it like to have surgery to correct a congenital hand disorder?

Children heal very quickly. After an operation that can take from one to several hours, a child will wear a cast for about four weeks and then move on to a splint and physical therapy. Full movement is typically restored after three months.
