Fracture at the Middle of the Forearm.If both bones be broken, the usual signs of fracture will be apparent. There will be an unnatural mobility of the arm - a grating sensation and loss of power. If, however only one bone be broken, these signs are less ap parent, for the other bone maintains the form and length of the arm. Sometimes, too, it is impossible to detect the grating sensation. In every case we should find the point at which pressure causes the patient acute pain, and observe whether this is on the outer or outer or inner side of the arm; that is, whether it is located over the radius or the ulna. We then pass the fingers along the course of the bone, feeling carefully for any point at which a little pressure is followed by a yielding of the bone. If we find such a point, we can sometimes, by placing the thumb of one hand over it, and the thumb of the other hand two or three inches higher up, distinguish a faint grating sensation. The peculiar impairment of motion may also enlighten us as to the location of the fracture. The radius, as has been said, is especially concerned in the rotation of the hand ; any injury to the radius is apt to be followed by an impairment in the power to turn the hand over. Treatment.-It has been already stated that injuries to the bones of the forearm are frequently followed by some impairment in the movements of the hand. It is extremely important that the fact be recognized in the treatment of the fracture. The first object of treatment must, therefore, be an effort to separate the bones at the point of fracture. In consequence of the arrangement of the muscles in the forearm, the broken ends of either bone are apt to be drawn toward the other bone ; unless this position is relieved, the two bones may grow together at the point of fracture, a condition which will result in serious loss of motion, since the hand cannot be rotated or turned over. In order to avoid this two splints of wood should be prepared, long enough to reach from the elbow to the wrist. The splint which is applied to the f*ont of the arm should extend down to the palm of the hand, so that the fingers can be bent up over it. These splints should be well padded and applied to the arm ; the padding (of cotton) should be made somewhat thicker in the middle, so that it shall sink in between the bones and keep them separate. In applying the splints care should be taken that the arm lies so that the palm is turned upward ; this is necessary in order that the bones shall be kept apart. In this position of the hand, the two bones of the forearm lie parallel and widely separated, while when the hand is in any other position the radius lies across the ulna and close to it. After the splints have been applied and fastened by means of a bandage, the arm should be supended in a sling, the palm of the hand being turned inward with the thumb uppermost. The dressing should be worn for about a month, and the arm should be carried in a sling for a week or two afterwards.
