. A practical treatise on fractures and dislocations. e bone to thecranium carries with it the possibility of associated injury to the brainor to its case ; retention of pus in a conipound fracture in conununioa- 182 FHA CTURES. tion with the cavity of the moiitli exposes to the grave danger of absorp-tion of the decomposed secretions and, thongh rarely, to tiie burrowingof .the decomposed pus along the deeper planes oif the neck into theanterior mediastinum. Treatment. Displacement following fracture of the body of the jawcan usually be readily overcome by the pressure of the thumb andfingers upon the teeth and the lower border of the bone ; in somecases the interlocking or wedging of the smaller pieces or of displacedteeth may render the reduction impossible until after they shall havebeen removed. In simple cases where the tendency to displacement is slight it issufficient to immobilize the lower jaw by binding it against the upperone with a four-tailed bandage, the centre of which is at the chin, asshown in Fig. 76. Fig. 76. Fig. Four-tailed bandage for fracture of thelower jaw. Kingsleys splint applied. Splints are applied either to the front and under surface of the jawoutside the mouth, or to the teeth, or the inner surface of the jaw, andtwo kinds are sometimes used in combination. Outside splints areavailable only in cases in which there is not much tendency to displace-ment and in which the lateral pressure of a simple bandage wouldcause the fragments to override in one direction or another. Theymay be made of leather, pasteboard, gutta-percha, or plaster of Paris,and consist essentially of a cup-shaped piece embracing the chin andextending nearly to the angle of the jaw on each side, and to the foldof the neck below. Interdental splints are made of metal, gutta-percha, or vulcanizedrubber; they are fitted to the crowns of the teeth of both fragmentsafter reduction of the displacement, and are held in place either bybinding the jaws together with an o
