I. TRANSPLANTATION OF THE PROXIMAL END OF THE ULNA TO THE DISTAL END OF THE RADIUS IN AN UNUNITED COLLES' FRACTURE
—Figures 1 and 2 show radiographs of the wrists and hands of W. M. Y., who, at the age of 9, suffered a compound right Colles' fracture which, becoming infected, resulted in non-union, destruction of the epiphysis, arrest of growth, and extensive atrophy of the proximal end of the radius.
—Six years later the boy was brought to me, and the comparative condition of the two extremities is here shown. The right hand was deflected sharply toward the radial side, and having no bony support, hung loose like a flail and was practically useless. The ulna continuing to grow, was slightly curved in the direction of the radius.
—The end of the posterior surface of the distal fragment of the broken radius was freshened by
