Fracture of the lowerjaw is a more frequentaccident. The conditionis easily recognized, eitherfrom without or throughthe mouth, so very littleneeds to be said about the diagnosis. In fractures of the body or arch of the lowerjaw a typical dislocation is observed, the posterior frag-ment being drawn upward by the masseter, while the an-terior fragment is displaced downward by the action of thedigastric and other muscles attached to the chin. In the great majority of cases there is also a certainlateral dislocation by virtue of which the two fragmentsoverride each other so that the arch of the bone becomesshorter and narrower. Double fracture of the lower jawis occasionally met with, and comminuted fractures arenot so very Fig. 26.—Specimen of fractureof the lower jaw with lateral dis-placement. 104 FBACWBES AND DISLOCATIONS.
