FRACTURES OF THE LOWER JAW. 



These take place in the anterior part occupied by the front 

 teeth, or more frequently on one side, between these and the 

 grinders. In simple fractures with no great tendency to move- 

 ment an exclusive diet of soft mashes will often suffice, a double 

 halter being so arranged that the animal cannot possibly reach 

 either fodder or litter. If the fracture is between the front 

 teeth a copper or silver wire wound round two teeth on 

 opposite sides of the break may fix the parts sufficiently. If 

 further back and very mobile, it may still be retained at times 

 by using the tushes as fixed points from which to carry the wire. 

 Where these cannot be availed of, the jaw may be perforated 

 by a fine drill in front of the fracture and behind it, and the 

 two parts firmly bound together by a silver wire. If this is not 

 available, a mould of gutta-percha or wood is made to fit the 

 lower jaw and sides of the face from the throat as far as the 

 chin, and this is strapped on by four belts, one passing behind 

 the ears, one in front of them, one on the middle of the face and 

 one on the nose but four inches above the nostrils. The straps 

 may be held together by another or a simple cord passing down 

 the middle of the face, and the two lower ones should be 

 slightly elastic. This should be kept on till union is effected, 

 and no hard food should be allowed for two months. 



In cases of compound comminuted fractures remove all 

 foreign bodies and detached pieces of bone, and make an 

 opening in the case, through which the wound may be 

 dressed with antiseptic liquids (carbolic acid i part, water 

 100 parts).
