SPRAINS. 509: 
clearly demonstrate the accident. In small animals, the reduction is.. 
generally easy with recent luxation. In the dog of Lafosse, after a 
few seconds of traction, a snap was heard, and the reduction obtained, .. 
the dog arose, and ran with only slight lameness. No bandage was ap-. 
plied. In a case of luxation with articular wound, Soumille obtained: 
the reduction as easily, but the accident returned as soon as the animal 
moved its leg; a contentive bandage had to be applied. Seven days. 
later, the dog used its leg; the bandage was removed; the articulation 
was normal, no swelling nor deformity ; the wound, much contracted, 
did not allow the escape of synovia. 
If luxation is old, reduction is sometimes very difficult. We had to.-. 
treat, in a pointer, a luxation of the elbow, mistaken for a fracture and 
immobilized for two months. Notwithstanding anesthesia and the help. . 
of several assistants, it was impossible to reduce it. Arthrotomy had 
to be performed from the internal face. The synovial open, a great 
quantity of reddish synovia escaped ; after partial section of the in- 
ternal lateral ligament, the radio-cubital articular surface, which had. 
deviated outwards, resumed its normal position. The recovery from. 
the operation was rapid, and the therapeutic result satisfactory. 
In large animals, though quite difficult, the manipulations are some-. 
times less hard than they were expected to be. Lapouse had the head 
of his mule held firmly, while two assistants supported the animal on 
the right side. Placéd back of the dislocated leg, he flexed the radius. 
to carry the olecranon backwards, then applied his right knee on the 
internal face of this bone while pushing the. lower extremity of the 
forearm inwards and the inferior end of the humerus towards the - 
thorax ; a snap was heard, the leg resumed its direction; the animal 
could walk immediately. _ A friction of ammoniacal liniment was made. 
on the articulation. Nine days after, locomotion was normal, and 
the horse resumed his work. 
- Decroix cast a horse and etherized him. Tractions made at the foot 
to bring the bones end to end failing (there was 6 centimeters short--.’ 
ening), the cannon was flexed, then two ropes placed, one on the lower 
extremity of the humerus pulled upwards, the other on the superior-~ 
part of the radius and drawn downwards, were given to assistants. In. 
a few minutes, the luxation was reduced. The joint was covered with 
melted pitch and oakum cut in small pieces. Twenty days later, the: 
horse went to work. 
To resume: in small animals, the reduction done early is easy, and 
the contention, during a few days, with bandaging, is enough to pre-
