Book excerpt: Excerpt from Transactions of the American Academy of Dental Science: December 4, 1889, to February 1, 1893 Deformity is general, but not always, present, and it may be a result of the cause which produced the injury or of the action of muscles upon the fragments. Preternatural mobility is an important symptom of fracture, and is rarely absent unless the fracture be impacted. The manner of repair in cases of fracture merits some consideration. The first stage, which is a period of preparation, occupies about one week. During this period, in favorable cases, inflammation subsides, the inflammatory products and extravasated blood are absorbed; pain, swelling, and traumatic fever disappear. From the eighth to the seventeenth or twentieth day the parts became red and injected, and covered with a layer of embryonic cells, and towards the end of this period the granulation tissue becomes more and more firm, until, finally, the tissue is converted into bone, forming, in the case of long bones, two layers, one within the medullary canal and the other encircling the ends of the fragments. This is known as the temporary or provisional callus, which is Nature's splint for holding the fragments in position until repair is rendered complete by the deposit of osseous tissue between the broken ends. The temporary callus, it may be stated, is much harder than normal bone. The final stage of repair, after the bone has been united by a sound bony tissue, consists in the absorption of the provisional callus, leaving the bone smooth and in proper condition for continued performance of its function. The whole process may occupy several months, and if the ends of the fragments are not in proper relation to each other the process may be rendered very long and tedious. In union of a fractured lower jaw the temporary callus is found to be much less than in ordinary long bones, the union being direct after the formation of a small encircling band of temporary callus. Surgeons declare that the treatment of fractures requires a greater amount of ready knowledge, skill, and judgment than any other department of surgery, and that they always approach them with some misgiving. Surgeons assure me, further, that fractures of the lower jaw are perhaps the most difficult of all fractures to treat successfully, or in such a manner that there shall be no subsequent impairment of function, no discomfort, and no deformity.
