What is Symbrachydactyly? Taking the word literally, sym means joined (like syn), brachy means short and dactyly means finger. So, the word means short joined fingers. Symbrachydactyly (sim-brake-dak ti-le) occurs during normal emybronic developement. When a babys hand begin to form in utero, they are shaped like mittens or paddles. Then the fingers divide. In babies with symbrachydactyly, the fingers (and sometimes the hand and arm) dont full form during this time. This may happen because the area doesnt get enough blood flow or because of some other problem with the tissue. It is not caused by anything the mother did or didnt do during pregnancy. Symbrachydactyly is often misdiagnosed as Amniotic Band Syndrome (ABS). There are 7 different classifications of symbrachydactyly. 1. short finger 2. cleft type (thumb and small finger present) 3. peromelic (nubbins) 4. monodactyly (only the thumb present) 5. wrist bones present (but nothing more distal) 6. wrist bones absent (ie, arm ends at the end of the forearm) 7. transforearm (amputation at mid-forearm level)
