Definition
Postaxial tetramelic oligodactyly is a rare, genetic, congenital limb malformation disorder characterized by isolated, postaxial oligodactyly in all four extremities. Patients present a consistent pattern of malformation ranging from complete absence of the 5th metacarpals, metatarsals and phalanges to complete absence of the 5th metacarpals and metatarsals, with some residual distal 5th phalanges. There have been no further descriptions in the literature since 1993.
