3 Common Congenital Hand Differences
A congenital hand difference is a hand that is abnormal at birth. During fetal development, the upper limbs are formed between four and eight weeks of pregnancy. During this time, many steps are needed to form a normal arm and hand. If any of these steps fail, then a congenital hand difference can result. It is not uncommon for a child to be born with a hand difference.
