SPECIAL INJURIES OF BONES. %\1 



INJURIES BY BIT AND CURB. 



These often cause slight fractures or superficial necrosis on the 

 upper or lower borders of the jaw. Extract detached pieces or 

 scrape off dead, and when the wound has healed drive with a snaffle. 



FRACTURE OF THE UPPER JAW. 



This is much less serious. If at the anterior part fix by 

 wiring the teeth together. If further back and associated with 

 discharge from the nose, trephine the sinus (see diseased teeth), 

 remove detached pieces of bone and inject with a weak astrin- 

 gent solution (diseased teeth). 



FRACTURE OF THE BONES OF THE NOSE. 



Here the depression of the space between the nostrils and 

 the difficulty of breathing are characteristic. Shave the skin 

 above and below the fracture ; make a smooth cone of wood 

 rounded at the apex and just large enough to fit the nasal pas- 

 sage ; with this inside the nose raise the bone to its proper 

 position and strap it there by strong adhesive plaster passing 

 over the interval of the fracture. In obstinate cases we can 

 resort to plugging of one nostril with tow, or of both nostrils if 

 tracheotomy has been first performed. 



FRACTURE OF THE FRONTAL BONES. 



If beneath the level of the eye the danger is slight, and after 

 removal of detached pieces of bone it may be treated like an 

 ordinary wound. If above, the depressed bone must be raised 

 with a lever to avoid compression of the brain when exudation 

 takes place. Fracture of the process which forms the upper 

 boundary of the eye-socket may be raised in the same manner 

 to avoid subsequent blemish.
