What is Congenital Hand Deformities ?

Congenital hand deformities are abnormalities in the structure or function of the hand that are present at birth. These deformities can affect the bones, muscles, tendons, nerves, and blood vessels of the hand, and can vary in severity from mild to severe.


Polydactyly: This is a condition where people are born with extra fingers or toes.

Syndactyly: This is a condition where two or more fingers or toes are fused together.

Radial dysplasia: This is a condition in which the radius of the forearm is underdeveloped, resulting in a shortened or absent thumb and limited wrist movement.

Ulnar dysplasia: This is a condition in which the ulna bone in the forearm is underdeveloped, bending the wrist and limiting forearm movement.


Treatment for congenital hand deformity depends on the specific condition and its severity. In some cases, surgery may be needed to correct the deformity and improve hand function. Physical and occupational therapy may also be recommended to improve hand strength and dexterity.


Congenital hand deformities are abnormalities that manifest in hand development during fetal development. The exact cause of these malformations is not always known, but there are several factors that contribute to their occurrence. Some of the most common causes of congenital hand deformities are:

Genetic factors: Some congenital hand malformations are caused by genetic mutations or chromosomal abnormalities that occur during fetal development. These abnormalities can affect hand development and lead to malformations.

Environmental Factors: Exposure to certain environmental factors during pregnancy may also contribute to the development of congenital hand malformations. These factors include alcohol, tobacco, and certain drugs.

Amniotic Band Syndrome: This is a condition in which a fibrous band of tissue forms within the amniotic sac and envelops the developing fetus, causing narrowing and deformity of the affected limb.

Maternal disorders: Some maternal disorders, such as rubella, can cause congenital hand malformations in the developing fetus.
