A practical treatise on fractures and dislocations . h occur through the middlethird, or between the rhomboid andcoraco-clavicular ligaments. In frac-tures near the sternal end, withinthe region occupied by the rhomboidligament, there is usually very littlepermanent displacement. The sameis true when the fracture is at theacromial end, and between the fas-ciculi of the coraco-clavicular liga-ments ; but if the fracture is beyondthese ligaments, near the acromialend, the final displacement and de-formity may be very great. Thepresence of a small amount of ensheathing callus soon after the cure iscompleted, sometimes increases the deformity. It is rarely seen to en-circle the bone completely, and occasionally it appears to be most abund-ant in the direction of the salient points of the fracture, that is, aboveand below; so that, unless the examination is made with care, the pro-jecting points of callus which remain, sometimes after many years, maybe easily mistaken for an intercepted fragment turned at right angles tothe axis of the Comminuted fracture.—United.(From nature.) Robert Smith has observed, also, that in cases of fracture external to theconoid ligament, osseous matter is freely formed upon the under surface of eachfragment, but there is seldom any deposited upon the upper surface of osseous growths, occupying the situation of the coraco-clavicular liga-ments, frequently prolong themselves as far as the coracoid process, and in some 180 FRACTURES OF THE CLAVICLE. cases to the notch of the scapula. Still less frequently these osteophytes becomefused with the coracoid process, and a true ankylosis exists. In comminuted fractures the intercepted fragments generally fall offfrom the line of the other fragments, and cannot easily be restored. Theclavicle, being a spongy and vascular bone, usually unites with greatrapidity, generally within twenty days.
