SECT. XCV.—ON THE BREAST-BONE.
The middle of the sternum is fractured by simple division and by expression, and the extremity of it is broken off. When, therefore, the fracture is deranged, pain and inequality of the place follow, and there is crepitus upon pressure with the fingers. When by expression, there is violent pain, dyspnœa, and cough, owing to the pleura being irritated; and rarely there is vomiting of blood, a hollow in the fractured place, and yielding thereof. The same treatment is to be applied as that recommended for the scapula. When the fracture is by expression, we may practise Hippocrates’s mode of setting which he recommended for the clavicle when it inclines inwards, having recourse to the supine posture, the application of a cushion upon the back, pressing down the shoulders, and drawing the sides together with the hands. The sides being covered with wool, we apply a circular bandage, having first put on two thongs straight from the shoulders, so that afterwards the two ends may be united in a proper manner, and prevent the circular bandage from falling off.
Commentary. Hippocrates holds injuries of the sternum to be more dangerous than those of the ribs. He recommends in this case a light diet, rest, silence, bleeding at the arm, and so forth. (De Artic. 50.)
Celsus directs this fracture to be treated upon general principles, as explained in [the preceding section].
The Arabians evidently follow our author. Albucasis speaks of applying thin splints.
The reader will find, upon reference to [the ninetieth section], that a fracture by expression is a comminuted fracture with depression.
