If your baby or child has been born with short fingers that are webbed or conjoined, a condition called symbrachydactyly, the specialists at Boston Children’s Hospital can help.

Here is some basic information about symbrachydactyly:

   •   In symbrachydactyly, the fingers are abnormally short and webbed (or
       “conjoined”). The bones, muscles, ligaments, and nerves of the hand
        are usually affected.
   •   Symbrachydactyly is rare, occurring in only about one in 32, 000 newborns. It doesn’t run in families, and
       affects boys and girls equally.
   •   It usually affects just one hand.
   •   In symbrachydactyly, the thumb and small finger can be larger than the middle fingers, forming a u-shaped
       pattern of the fingers.
   •   The condition can range from fairly mild to severe.
   •   It can be associated with a genetic condition called Poland syndrome, which also involves underdevelopment
       or absence of the chest muscle on one side of the body.
   •   Many forms of symbrachydactyly are treated surgically. Surgery is usually done when the child is between 6
       and 18 months old. Sometimes, a series of surgeries performed over a period of years is needed.

You can have peace of mind knowing that the skilled experts in our Hand and Orthopedic Upper Extremity Program have treated thousands of babies and children with many bone-related conditions.  We provide expert diagnosis, treatment and care, and we benefit from our advanced clinical and scientific research.

The Hand and Reconstructive Microsurgery Program

The specialists in the Hand and Reconstructive Microsurgery Program at 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.
