(Compare Plate 46 andPlate 47, Fig. 1.) lower extremity deserves especial notice ; it is comparableto a supramalleolar fracture of the leg, hence the term supra-condylar has been proposed. This fracture, like typicalepiphyseal separation of the radius, is produced by a fallon the hand. Owing to the marked deformity, the diagno=sis rarely presents any difficulties. The treatment calls for careful reduction and fixation,either in supination or midway between pronation and 200 FRACTURES AND DISLOCATIONS. PLATE 41. Various Fractures of the Forearm and Normal EpiphysealLines.—Fig. 1.—Specimen of fracture of the forearm (right) withcohesion of the callus of both bones at the seat of fracture. Thisunfortunate condition is due partly to the abundance of callus andmore particularly to the fact that the two fragments of each bone tendto converge. The illustration distinctly shows this abno
