Macrodactyly

Macrodactyly is an uncommon condition in which a baby’s toes or fingers are abnormally large due to the overgrowth of the underlying bone and soft tissue. The condition is congenital, meaning babies are born with it.

• Macrodactyly happens more often to hands than feet.
• Most of the time, only one hand or one foot is affected, but usually more than one digit on that hand or foot is involved.
• Macrodactyly may coexist with syndactyly, a condition in which two fingers or toes are fused together.
• Although it is a benign condition, macrodactyly is deforming and can look cosmetically displeasing to you and your child.

Surgery, usually involving multiple procedures, can help the problem.
