Abstract

Definition and Etiology of Fracture.

The word fracture, to break, or in other words, breaking, conveys to the mind so clear an idea, that a definition perhaps might tend to obscure it. Many definitions have been given. Grove defined fracture as a division of the bony fibers occasioned by external violence or muscular contraction. Richard Wersman, in the 17th century defined fracture as a solution of continuity in bone suddenly made either by contusion or flexure.

In considering the relative frequency of various kinds of fractures Stimeon says: "The liability to fracture of the different bones of the body varies greatly in consequence of their difference in size, shape and degree of exposure to external violence of extreme muscular action." Consequently on account of the more exposed position, shape and lack of support, the mandible is more susceptible to fracture than that of the maxillae. In a classification of 2,358 fractures of the different bones of the body, 27 fractures of the mandible were observed and only three of the maxillae, making a ratio of 9 to 1. Lyons records coincide with the ratio.
