EXOSTOSIS. 477° 
he splint becomes more or less developed ; blistering preparations are nec—- 
issary. 
Hammering with the back of the hammer of the plessimeter, followed 
oy a blistering application, succeeds in a number of cases. The whole sur-- 
ace of the splint is hammered .with light strokes, without bruising the - 
ikin, and then a blister put on. 
When, by blistering, one succeeds in reducing or removing the lameness, 
ilthough the tumor remains, the animal may be returned to work. It is. 
iseless to try to obtain the resolution of the exostosis by firing ; as remarked 
Lagardere and Liard, it often resorbs spontaneously as the animal gets 
older. 
To obtain the “melting” of splints, massage and pressure have also. 
been used (L. Lafosse, Mller). This is done by the application of a piece 
of sheet of lead or thick leather which is applied on the exostosis and held 
up by turns of rollers. Often, in afew weeks, the exostosis has diminished. 
in a noticeable manner. The dressing is renewed every day; the skin 
must be carefully watched to avoid the necrosis. 
If these means fail, cauterization must be resorted to—actual firing in 
lines, superficial or deep points. Notwithstanding the remarks of Liard,. 
we use this last mode; like Abadie and many others, we have obtained. 
very good results with it. We puncture the skin through by one or two. 
strokes of the instrument, and apply a stiff blister to complete the action 
of the firing. 
Periostotomy, recommended by Sewell, has been successful with Bouley, 
Haubner, Williams, Dammann, Ehlers. It must be performed aseptically, 
to avoid accidents by necrosis. During the eight days following there occurs. . 
a slight inflammation. According to Sewell, the animal can resume work 
eight or ten days aftet the operation; often the growth is resorbed. 
entirely. 
Ablation of splints is possible only for those that are projecting, pedun—. 
culated, or situated far from the tendons. L. Lafosse has done it with | 
chisel and hammer, “without having any accident to regret and without. 
blemishes afterwards.” 
Median neurotomy may relieve splints that resist all those means of 
treatment and in which the lameness persists. 
English authors call sore-shin a peculiar affection of the cannon bone, . 
which is common in race-horses. According to Cagny, it is specially fre-- 
quent in colts of eighteen months to two years ; it is rare at three and. 
absolutely exceptional in older animals. It always began during training. 
The excessive lameness that it gives rise to, when one leg only is affected ;~ 
the peculiar mode of standing of the subjects when both legs are suffering,.. 
may lead us astray in the diagnosis, and make believe to be navicular disease: -
