A practical treatise on fractures and dislocations . t of the whole number of fractures ofthis bone recorded by me, amounting in all to one hundred and nine,only eight belonged to the middle third ; an observation which is instriking contrast with the remark of Chelius, that it is broken mostfrequently in its middle. If the fragments are completely separated in the middle third, thelower end of the upper half is drawn forwards by the action of the bicepsaided by the pronator radii teres, in case the fracture is below its inser-tion; while the lower fragment is tilted toward the ulna by the con-joined action of the supinator radii longus and pronator as to the direction of the displacement much will depend upon thedirection of the force bv which the fracture has been occasioned. FRACTURES OF THE HEAD OF THE RADIUS. 285 A laboring man, set. 35, broke the radius near the lower end of themiddle third. On the same day I replaced the fragments as well as Icould in the midst of the swelling which had already occurred, and Fig. 93. Fracture of the shaft of the radius. (From Gray.) applied two broad and well-padded splints, one to the palmar and oneto the dorsal surface of the forearm. On the twenty-eighth day I first discovered that the fragments wereprojecting in front, and I at once proposed to thrust them back byforce, but the patient declined allowing me to do so. I then applied acompress near the summit of the projection, but not exactly upon it,lest it should cause ulceration, and secured over this a firm splint. Atfirst this seemed to produce a change in the fragments, but after acouple of weeks I found there was no improvement, and it was discon-tinued. About six months after the fracture occurred, this man hadthe same arm terribly lacerated in a railroad accident, and I wasobliged to amputate near the shoulder-joint; and I thus obtained thebroken radius. The bone was firmly united, but with an angle, salientforwards, of about ten degrees. There was no
