Macrodactyly in Children

  • 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.

    Boston Children's Hospital's approach

    Combining training in adult and pediatric orthopedics, hand surgery, plastic surgery and microsurgery allows our surgeons to provide a comprehensive level of care unmatched in most other hospital settings.

    Hand and Orthopedic Upper Extremity Program

    The Hand and Orthopedic Upper Extremity Program provides comprehensive care involving occupational and physical therapy, splinting, casting and reconstructive surgeries for infants, children and adolescents with complex congenital, neuromuscular, sports-related oncologic and traumatic upper limb conditions.

    Hand and Reconstructive Microsurgery Program

    The specialists in the Hand and Reconstructive Microsurgery Program at Boston Children's are experts in the management of congenital and acquired hand deformities. We recognize the social elements involved in pediatric hand surgery, so an essential part of these operations has been making the child's hand as symmetrical as possible with his unaffected hand.
