FRACTURES OF THE OS CALCIS ; RESULT OF MUSCULAR 
EFFORTS. 
By Mr. Detroye. 
The following observations derive their principal interest 
from the manner in which the lesions to which they refer oc¬ 
curred. A bull fifteen months old in attempting to cover a 
cow had raised himself about on a level with her croup, when 
a sudden noise like that of the breaking of a dry piece of wood 
was heard, and the animal fell down on his hind quarters. 
When he got upon his feet he walked on three legs, dragging 
the right leg, the anterior face of the foot resting on the 
ground. The next day the hock was slightly swollen, and the 
point of it less prominent. The tibio-calcanean triangular 
space had disappeared, the crepitation was well marked, and 
there was an oblique fracture of the os calcis, in the middle 
of the bone. A splint was made with a piece of sheet iron, 
made in the form of a trough or gutter, in order to adapt 
itself to the anterior face of the leg and of the hock, and se¬ 
cured by four leather straps, two above and two below the 
hock, and extending, therefore, from the middle of the tibia to 
the middle of the cannon bone. This was well padded, and so 
adjusted to the leg as to keep it in perfect extension. After 
three weeks the animal beeame restless, and displaced the 
splint, and when it was removed the foot rested flat on the 
ground, the hock had resumed its normal shape, with scarce¬ 
ly any malformation, and the patient stood upon his leg. In 
a few weeks the recovery was complete, and the lameness had 
subsided, notwithstanding the presence of the callus that re¬ 
mained. 
2d. An old horse while lying down made a sudden effort 
to rise. At that moment his right hind leg slipped backwards, 
and to avoid a fall, another effort was made, which failed, and 
the animal fell, unable to rise. A fracture of the os calcis 
near its articulation with the astragalus was readily recognized; 
and the animal was destroyed.
