Multiple exostotic deformities involving the metacarpals, radius, and ulna, with subjacent medullary continuity. These are predominately metaphyseal in location and oriented away from the joint. A large sessile exostosis is noted along the radial aspect of the ulnar diaphysis which extends beyond the field of view. The radius is bowed, with an increased unlar inclination of the distal articular surface. The distal ulna is markedly short, terminating approximately 1.5cm proximal to the radius.
