Congenital Hand Differences

Overview | Conditions | Referrals

WHAT ARE CONGENITAL HAND DIFFERENCES?

Congenital hand conditions are differences (anomalies) in the hand and arm that occur when a child is developing before birth. 

The anomaly may occur by itself or can be associated with problems with other body systems. The musculoskeletal (bones and muscles), cardiovascular (heart, arteries and veins), craniofacial (head and face) or neurological (brain, spinal cord and nerves) systems are most commonly involved. When a hand anomaly is part of a syndrome, a geneticist and/or other specialists may be involved with the child's care. Congenital hand anomalies may have genetic, environmental or unknown origin.

There are many different types of congenital hand conditions. Some of the more common anomalies include:

  • having more or fewer than five fingers
  • fingers that will not bend or will not straighten
  • fingers that are joined together
  • bones in the hand or arm that are too short or missing

Below you will see a list of some of the more common anomalies organized into their classification groups.
