Ulnar hemimelia is a rare congenital disorder characterized by absence of the ulna with an estimated incidence of 1/100,000-150,000 live births. The etiology of this disease remains uncertain, however it is thought that the deformity develops between the 4th and 7th week of gestation. The disease can be either partial or complete, and can be found in isolation or in association with other skeletal dysplasias such as Gorlin-Goltz Syndrome, Cornelia de Lange syndrome, Klippel-Feil syndrome, finger anomalies including syndactyly and oligodactyly. The purpose of this educational review is to describe the characteristic imaging findings of ulnar hemimelia with attention paid to clinically important associated features; review the differential diagnosis for ulnar anomalies; and discuss the range of congenital anomalies that can be associated with this condition. We will also perform a brief review of the literature concerning this rare entity, present two cases of complete ulnar hemimelia with oligodactyly from our institution, and review the various treatment options.
