PARALYSIS. 401 
extensors of the metcarpus and of the phalanges are affected in the fore~ 
legs, and the flexor metatarsi in the hind. Recovery is ordinarily easily 
‘obtained by massotherapy, and simple dry frictions.

L.—Sus-Scapular Nerve. 
The sus-scapular nerve, which ramifies in the antea and postea spinatus 
muscles, can be injured 
in various circumstances: by bruises against the 
‘shoulder, especially those which occur from forward backward when the 
jeg is raised to be car- 
ried forward (Moller) 
‘or by a blow, at the 
time of a fall, or by a 
slip in abduction. In 
army horses it has been 
observed without be- 
ing able to attribute 
it to any other cause 
than powerful muscu- 
Jar efforts or suddenly 
executed movements. 
We have observed it 
after the securing in de- 
cubital position. After 
two months the atrophy 
of the subspinatus spe- 
cially was well marked. 
(Fig. 92.) Under the 
title of Laceration of 
the Tendons of the 
Subspinatus, Bouley 1e- 
Jates two similar facts. 
(See Zendinous Rupt- 
ures.) In some cases,

nature or related to hemoglobinuria. For Biot, it is muscular congestion 
which, giving rise to “ hemorrhagic raptus,” injures the sus-scapular ; the 
sweenied shoulder is but “the consequence of the compression and in- 
filtration of the sus-scapular, by blood extravasated in nature round it and 
in its structure.”
