The fracture may beproduced by direct, butmore frequently by in-direct, violence, such asa fall on the hand withthe elbow in extension orflexion, a piece beingbroken out of the headof the radius at the eminentia capitata—so-called chisel-fracture. Treatment.—As we have no means of directly influ-encing the position of the fragment, recovery often leavesconsiderable deformity. In the dressing, the elbow- andwrist-joints are of course to be placed at rest, and direct. r Fig. 92. Fig. 93. Figs. 92 and 93.—Fracture of thehead of the radius in a womantwenty-eight years old, produced bya fall on the outstretched elbow-joint forms an obtuse an-gle. Pronation difficult. The headof the radius projects. (1889). The fragment wasunited to the bone in a position ofdislocation. FRACTURES OF THE UPPER EXTREMITY. 213 pressure may be applied to the head of the radius. Butin spite of every form of treatment indicated for joint-fractures, considerable stiffness of the elbow-joint mayremain, and later make it necessary to resect the head ofthe radius. The radial nerve is sometimes injured in thisfracture. Fracture of the neck of the radius—that is, below thehead—is very rare. The chief symptom is a failure ofthe head to move with the bone in pronation and supina-tion ; a bony prominence may be felt at the seat offracture. The treatment is the same as for the last variety.
