242 INJURIES. 



Fractured Nasal Bones. — This accident is commonly accompanied 

 with laceration of the Schneiderian membrane and hemorrhage, with or 

 without displacement of the bones themselves. When there is displace- 

 ment, it is mostly inwards, seldom outwards, and this impedes respiration, 

 especially when swelling supervenes. Should there be splinters, they 

 must be withdrawn through the external wound ; after which, with the 

 aid of the elevator and long forceps, the depressed bones may be raised, 

 and confined in their places by bandages. The swelling may be such 

 as not only to render the removal of the bandage advisable, but even 

 safe, on account of the support now given by the tumefied parts. In 

 cases where the displacement is outward, H. d'Arboval recommends two 

 supporters to be attached to the sides of a bridle, imagining that they 

 will give the requisite support, while they leave the motion of the jaw 

 unconfined. As for any apertures that may be left, they need not ^ve 

 us concern. They may be as much as possible covered by skin ; 

 or else some leathern covering may be fastened over them. These frac- 

 tures sometimes give rise to symptoms resembling glanders : such cases 

 have been mistaken. If unreduced or ununited, they may occasion roar- 

 ing or high-blowing. In this condition they are also attended with fetid 

 discharges ; enlarged submaxillary glands ; sometimes exostosis ; and, 

 within the nasal chamber, a projecting callus. (Hurtrel d'Arboval.) 



Fractured Superior Maxillary Bone has been treated by Mr. Cart- 

 wright, of Whitchurch. The depressed part was forced down upon the 

 maxillary sinuses, and could not by the elevator alone be replaced. Mr. 

 Cartwright, therefore, applied the trephine, and with it removed the in- 

 jured parts, which he found to consist of many small pieces. Adhesive 

 plasters were then used to cover up the wound. In a month the parts 

 were healed, without any symptoms of glanders supervening. 



Fracture of the Os Hygides. — For a case of this singular, if not 

 unique, accident, vide ' Veterinarian,' vol. xxvi, No. for December. 



Fractured Lower Jaw happens oftener at the symphysis than at 

 other parts. J. Field details a case in which the lower jaw was fractured 

 in two places by a blow ; one about two inches from the symphysis ; 

 the other in the situation of the submaxillary artery, which was"divided 

 by the accident, and bled freely, but which was closed by compresses 

 of tow. The horse died, however, within a fortnight, of constitutional 

 irritation. 



Happening to be in Mr. Cherry's yard, I accidently cast my eye upon 

 , a horse which had the lower jaw so much on one side that the only ap- 

 proximation between it and the upper, was by the corner incisor of one 

 meeting the corner incisor tooth of the other. I examined it at the 

 articulation, and, as far as I could make out, thought that it proceeded 

 from a fracture of the neck of the condyle, which from bad, or no treat-
