Wounds constitute always a serious complication. Deep wounds 
which involve the traumatic center, ordinarily bring on arthritis and anky- 
losis ; however, these are not fatal. As for the superficial lesions, 
antisepsy permits their cicatrization without infectious accidents. 
Luxations complicated with fracture are, economically speaking, 
incurable in our large animals. In small species, the luxation should 
be reduced, and the fracture immobilized after its reduction. 
LuxaTION OF EXTREMITIES. 
LI.— Shoulder Joint. 
Protected by thick muscular layers, the scapulo-humera! articulation 
is rarely affected with luxation. It is complete or incomplete. Hurtsel, : 
D’Arboval, Mathorez, Roloff, Hertwig, Seyler have reported cases in 
horses; Matheron, Lodezzano, Bossetto and Seyler in cattle; many. 
have seen it in dogs. It is sometimes accompanied with fracture of the 
glenoid cavity (Rigot, Lavocat, Lafosse). In reading the published 
observations, one is convinced that the humeral head is generally lux- 
ated forward ; though luxations backwards, inwards and outwards are also 
observed. Ifit is sometimes difficult to detect the precise direction of the 
displacement, the symptoms are enough characterized to differentiate 
the luxation from a fracture, the only accident for which it may be 
mistaken. Sometimes, the animal has fallen forward, on the side, or 
-when the leg was greatly in abduction ; at others, in a race, the leg has 
violently struck against an obstacle (Hertwig, Smith). The horse of 
the Observation I. of Seyler was mounted; he stumbled and fell. 
When up, it was found that “there was no movement at the scapulo- 
humeral joint, the head of the humerus was protruding forward, and be- 
tween it and the glenoid cavity there was a wide depression.” ’ : 
All authors consider this luxation an excessively serious lesion, on 
account of the difficulty of reduction and contention. 
Let us see how reduction must be made. According to Kaiser, 
nothing is easier with bovines. He says: Fix a rope at the fold of the 
pastern, carry the leg forward and upward until it can be secured to 
‘the horn of the same side and make the animal run. During this ex- 
‘ercise, the reduction takes place. Then make an irritating friction on 
the point of the shoulder. Bossetto recommends the following method :
