DISEASES OF THE MUOOTJS BURSA 237 



Which is the most common cause of calcanian bursitis ? 



This condition, also termed capped hock, is frequently- 

 seen in horses which, as a vice, bang their hocks against the 

 stall partition. When backing a horse, and the hold back 

 3)art of the harness is too long, the animal -will strike the 

 point of the os calcis frequently against the whiffletree and 

 'thus bruise the bursa. 



What are the symptoms of acute bursitis f 



There is a swelling of variable consistency, possibly fluc- 

 tuating or rather firm, more or less edema of the parabursal 

 tissue (tissue surrounding the bursa), but little pain on palpa- 

 tion. 



'Outline the treatrnent of acute bursitis. 



The first thing consists in the removal of the direct cause, 

 such as padding the stall partition for a kicker, changing the 

 shoe, giving plenty bedding or a box stall, etc. Wherever 

 possible, try to absorb the serous fluid and avoid the opening 

 >of the distended- bursa while acutely inflamed, as a purulent 

 bursitis, which is tedious to treat, is almost sure to follow an 

 incision. 



Purulent Bursitis, 



W hat is purulent bursitis ? 



An inflammation of the bursa with pus formation. 



What are the causes ofpu/rulent bu/rsitis ? 



It may be the consequence of incising a serous bursitis, 

 pus germs entering the bursa through the wound, or it may 

 follow a contusion sufficiently severe to destroy the solution 

 of continuity of the overlying skin with a wound extending 

 into the bursa.
