Ectrodactyly (derived from Greek ektroma [abortion] and daktylos [finger]) refers to a situation where at least one entire digit (both metacarpal/metatarsal and phalanges) is missing. It is a nonspecific term applied to a variety of malformations. The usual presentation is the absence of the third digit that creates a cone-shaped cleft that tapers in toward the wrist and divides the hand into two parts. The resulting deformation resembles a lobster claw. Affected individuals have normal life spans and intelligence. It is important not to confound the “atypical cleft hand,” referred to as symbrachydactyly as part of the Ectrodactyly Syndrome. It is not a subtype of the Cleft Hand Syndrome.
