Congenital Malformation of the Upper Limb (Ulnar Clubhand) in a 6 Year Old Child Treated by Lengthening Associated with Flexible Intramedullary Nailing

Congenital ulnar clubhand (type 1, Bayne’s classification) is shortening combined with ulnar deviation of the hand, dislocation of the radial head, and deformity of the radius. Forearm bone lengthening with restoration of correct proportions, deformity elimination, and reduction of the radial head can be successfully performed with the combined technique: circular external fixator and flexible intramedullary nailing. In this case we describe application of the combined technique which enabled correction of all the abovementioned defects as well as to shorten the period of external fixation significantly.
