Upper limb triplication with radial dimelia.
We report a very unusual case of upper limb triplication. The fused upper two limbs present as a duplicated mirror hand, joined along the ulnar side from the small finger up to the humerus. This exceptional abnormality further corroborates the theory that the development of the more distal segments of the limb is determined by the more proximal segments.
