PARTICULAR FRACTURES

properly readjusted, after which the broken bone may be fixed in position 

 by means of copper wire or whip-cord tied round the incisor teeth. 



To guard against disphrcement the patient must be made to stand 

 in the pillar reins, and for two to three weeks his food should be soft and 

 sloppy, such as scalded bran and chaft', boiled 

 roots, &c. 



In fracture of the branches or the body of 

 the lower jaw the cradle designed by Mr. 

 Walker of Bradford, shown in fig. 333, may 

 be used, or a piece of gutta percha, first soaked 

 in hot water, should be moulded on to the 

 under surface and sides of the lower jaw, and 

 made to fit into the hollow (intermaxillary 

 space) between its branches. By then punch- 

 ing four or five holes through the front border 

 on either side, and one or two into the upper 

 border, it may be made secure by strings or 

 straps passing in front of the face and behind 

 the ears. 



Mr. Walker's cradle is composed of two 

 lateral portions, fitting to the sides of the face, 

 suspended from behind the ears by a padded 

 strap A, and kept in position by a brow-band 

 B, throat- strap c, and jaw-straps F F F F, with 

 a central portion of wood padded with leather 

 D, to fit between the branches of the jaw, 

 and two flanges e e to rest on the first molar 

 on each side of it, the side plates having an 

 arrangement for adjusting their length and 

 screws H H for clamping them when adjusted. 

 In order that the flanees should have a level 



o 



bearing and allow the animal to eat, the first 

 molars on which they rest must be short- 

 ened by tooth shears (fig. 334) or rasp (fig. 

 335). The apparatus should be so adjusted 

 as to lie evenly and without pressing more on one part than another. 



In the absence of these appliances an adhesive compound of Burgundy 

 pitch, Venice turpentine, and a little bees'-wax may be plastered over and 

 round about the seat of fracture in a succession of layers until a thick 

 strong covering has been obtained. This when set will give considerable 

 support to the broken parts.
