Ill 



lotion pack. When the inflammation has disappeared, apply a 

 blister of trinioctide of mercury and keep the animal quiet in a level 

 stall for three weeks. 



DISLOCATIONS. 



392. A dislocation is the displacement or separation of the parts 

 of a joint. 



393. Dislocation of the patella (stifled). A displacement of 

 the patella from the end of. the 



femur. The displacement 



ay be upward or outward. 

 Causes. Falls , slipping 



when trying to get up, and step- 

 ping down from an elevated 

 position to the ground or floor 

 below. It occurs sometimes 

 as a result of weakness after or 

 during the course of debili- 

 tating diseases. 



Symptoms . The d isplace- 

 ment may be stationary, or the 

 patella may slip in and out with 

 every step. In the former, the 

 leg is rigidly extend ed^back- 

 ward, the horse, even with as- 

 sistance, being unable to bend 

 the leg or carry it forward . 



Treatment. Reduce the dis- 

 location. By suddenly mov- 

 ing the animal backward the 

 bone may return to its normal 

 position. This failing, a rope 

 is placed around the pastern 

 and the leg drawn forward 

 and upward by an assistant, at the same time the operator presses 

 the patella forward and inward with both hands. As the bone goes 

 into place a clicking sound may be heard, and the animal at once 

 regains control of the leg. 



If the Joint be painful and swollen, shower with cold water and 

 bathe with white lotion until the inflammation is reduced, then 

 apply a cantharides blister and give four weeks' rest.
