ing sound, won a prize in every class he was entered in at Madi¬ 
son Square Garden that fall, which were three, sold for $1500, 
worked all last season at Newport and turned out last fall, and 
has not taken a lame step on the leg operated upon. 
Bony growths at inside of fetlock experience positive relief 
unless, as in the knee, there is anchylosis, same with coronet. In 
cases where we have sidebones it is very difficult to determine 
which one is causing the lameness, as I have found that it need 
not of necessity be both, but only one which gives rise to the 
lameness. This can be detected by injecting cocaine over the 
inside plantar nerve and if the lameness disappears median neu¬ 
rectomy is of great service. 
In navicular disease it is far more preferable in heavy draft 
horses than plantar neurectomy, as it will relieve the lameness 
sufficiently to enable the animal to work, and has the advantage 
of not removing all sensation from the foot. Of course, it 
would not be as effectual in driving horses, but then, perhaps, 
when not too bad it might be resorted to in them, and if not 
lasting in the relief afforded it would be only a simple matter to 
excise the outside plantar nerve and make digital neurectomy 
complete. 
The first case I operated upon was on December 24, 1896, 
and I have yet to record any deleterious results which could be 
traced to the operation, so that Rues’ questions which were given 
in the early part of this paper have been satisfactorily disposed 
of. 
Baldoni states that he has seen cases of shoulder lameness 
cured by this operation, but I can only agree with C. Pellerin 
when he says that those cases must have been ones of mistaken 
diagnosis. 
The value of this operation for relief of lameness which has 
resisted firing and blistering several times, appeals to me most 
strongly from my experience with it, as I am positive that many 
an animal has been destroyed as incurable that might have been 
of service for many years had median neurectomy been per¬ 
formed.
