RUPTURES. 26s 
anterior straight muscle ; but the reading of his case shows that the lesions 
he met had occurred during an attack of hemoglobinuria. At the post- 
mortem examination of a horse whose “ entire muscular system” was dis- 
colored, Salle and Sergent found ruptures of the short adductor, of the 
thigh, and of the external ischio-tibial muscle.* Krashe has recorded 
the case of a horse which was lame for a Jong while in one hind leg, and 
which one morning was found with it all deformed; the leg and thigh 
were much tumefied, the femur and tibia almost on a straight line, the 
hock much flexed on the tibia, to such an extent that at each step the 
point of the hock would touch the ground. Having been destroyed, at 
the post-mortem examination the gastrocnemius externus and internus 
were entirely torn at their superior attachment and extensively diseased 
with old degenerating myositis. A plate in Stockfleth’s “ Surgery ’’ 
shows a cow whose hock almost touches the ground, and in which the 
gemini of the corresponding leg were found ruptured near their femoral in- 
sertion.3 Some muscular ruptures are accompanied with some spinal 
diseases; that of the abdominal muscles ordinarily gives rise to hernia: 
that of the intercostals to pneumocele. In the observation of Jacotin, 
under the title of ‘‘ Rupture of the Aponeurosis of the Great Serratus,” 
as in that of Bouley of “‘ Rupture of the Tendon of the Postea-Spinatus,” it 
was a question of a paralysis of the sus-scapular nerve. 
« Dr. Pendry has recorded the case of a trotting-horse which became lame 
and which by the peculiar history he suspected to be suffering with in- 
complete fracture of the femur. After a few days of treatment (slings and 
blister) the animal was found in the morning with a fracture of the lower 
extremity of the tibia. On making minute dissection of the leg and examining 
the condition of the ischio-tibial muscles he found a laceration. of the anterior 
portion of the long vastus muscle, with large ante-mortem clots on its deep sur 
face. (Amer. Vet. Review, vol. 8, p. 412.) 
2 Cases of rupture of the flexor metatarsi are recorded in the American 
Veterinary Review by Abele, in which recovery was quite rapid. After three 
weeks the lameness was hardly perceptible. (Vol. 20, p. 573.) In the observa- 
tion of Lusk the horse walked quite sound after four weeks and resumed work 
aweek later. (Vol. 21, p. 257.) A fatal case is also recorded from the clinic 
of a veterinary college in Chicago, in which at post mortem was found ‘‘ an 
almost entire rupture of the tendinous portion of the flexor metatarsi with partial 
rupture of the muscular portion.” The accident occurred while the horse was at 
work ; he slipped on the ice, and on attempting to rise his near hind foot slipped 
back. (Vol. 22, p. 767.) 
3 Dr. Schreibler has reported a case of complete laceration of the gastroc- 
nemius tendon in a greyhound, which was completely severed. The separate 
ends of the tendon were about one inch apart and the rupture about an inch 
and a half from the apex of the os calcis. The leg was placed in splints and 
left for about a month, when the dog was discharged. There remained much 
lameness, due to excessive atrophy of the muscles of the leg, (Amer, Vet, 
Review, vol. 9, Ps 467+)
