external ligaments were irregularly torn from their insertion to the tibia. 
The capsule of the anterior face of the articulation was torn in its mid- 
dle. There was no motion possible in the articulation.” ? 
All varieties of luxation of the hock are very serious. Recovery, 
‘when it is obtained, is always imperfect. On this account most animals 
‘suffering with it are destroyed. Schrader has published a recovery 
“of luxation of the metatarsus in a cow; Stockfleth, with a cat suffering 
with subastragalean luxation, had success in reducing it and immobilizing 
the leg with an india-rubber band. In small species treatment might be 
undertaken. By extension, counter-extension and manipulation applied 
an inverse direction upon the inferior extremity of the tibia and the 
superior of the metatarsus, the luxation might be reduced. A pitched 
or plastered bandage would insure immobilization.

Accarding to d’Arboval, metacarpo or metatarso-phalangeal luxations 
are frequent. With Peuch and Toussaint, we believe that they are rare. 
‘They occur in yarious circumstances, but their ordinary causes are those 
which, acting with less violence, give rise to sprain of the joint. Cases 
are related in solipeds and bovines. 
The lesions are sometimes extensive, and death may follow rapidly 
. (Aureggio). Ona horse seen by Lecoq, the inferior extremity of the 
‘metacarpal, which had perforated the skin, was exposed for a length of 
ro centimeters; the lateral ligaments were ruptured, the phalanges and 
the foot thrown backward and outward in such a manner that 
the foot was on a level with the lower end of the metacarpal. Same 
serious nature of the lesions on the patient of Romary: phalanges 
thrown backward of the metacarpal, which, having perforated the skin, 
came in contact with the foot. In the observation of Neumann the

Wray has recorded the case of a mare, which in a runaway accident 
‘had a complete luxation of the tibia and astragalus on the left hind leg, so that 
the tibia and metatarsus formed a complete right angle. The mare was 
secured, the luxation reduced, strong hickory splints and bandages were applied. 
and the animal placed in slings, where she was kept for nearly a month, after 
which she was discharged, apparently sound, with the exception of a slight 
swelling of the joint, which gradually disappeared._Amer. Vet. Review, Vol. 
, P- 20. 
: Dr Townsend has reported the case of a cow, which had also a luxation of 
the tibio-tarsal joint after a fall, in which the lower part of the leg was dislo- 
. cated outwards and forwards. The luxation was reduced at once. The leg was 
bathed in warm water, and when the inflammation had subsided oil of turpen- 
tine was rubbed. The cow remained lame.—Amer. Vet. Review, Vol. 7, p. 75.
