Ectrodactyly, commonly known as lobster claw syndrome,[1] sometimes known as Karsch-Neugebauer syndrome, is a rare congenital deformity of the hand where the middle digit is missing, and the hand is cleft where the metacarpal of the finger should be. This split gives the hands the appearance of lobster claws. Ectrodactyly is an autosomal dominant disorder.
Ectrodactyly may also be known as "lobster claw hand", "split hand deformity", "split hand/foot malformation (SHFM)", "cleft hand", "ectrodactilia of the hand" or "Karsch-Neugebauer syndrome", after J. Karsch[2] and H. Neugebauer.[3]
