Ectrodactyly, split hand, cleft hand, derived from the Greek ektroma (abortion) and daktylos (finger) involves the deficiency or absence of one or more central digits of the hand or foot and is also known as split hand/split foot malformation (SHFM). The hands and feet of people with ectrodactyly are often described as "claw-like" and may include only the thumb and one finger with similar abnormalities of the feet.
