Ulnar hemimelia is a rare congenital upper limb anomaly characterized by complete or partial absence of the ulna bone. Oligodactyly and shortening of forearm is noted with ulnar tilt of the wrist joint. The position of the hand tends to drift to the ulnar-side of the wrist. Cubital webbing with fixed flexion deformity of the elbow joint is also seen in most cases. Patients with ulnar hemimelia have motion and functional limitations as well.
