322 VETERINARY SURGICAL THERAPEUTICS, 
There is sometimes an abundant hemorrhage, but a simple ligature or a 
compressive bandage are sufficient to stop it. 
According to Chassaing, the section of the tendon of the external flexor 
is all that is required in the majority of cases. But if the bend of the 
knee is great, double tenotomy is preferable. 
Sometimes the straightening of the knee takes place immediately, at 
others it requires some time. In the cases where the knee has a tendency 
to bend backwards, the padded apparatus of Brachet or the orthosome of 
Brogniez can be used with advantage. In this way the articulation is kept 
in normal condition until the cicatrization is completed, and when the 
apparatus is removed, after about twenty days, the knee keeps the position 
which it has received. - 
When the deviation seems due to a simultaneous retraction of the 
flexors of the metacarpus and of those of the phalanges, it is, as suggested 
by Lafosse, proper to complete the suscarpal tenotomy by that of the 
perforans. In a twelve-days old colt, Chassaing made the section of ex- 
ternal flexor, and a month later double plantar tenotomy. Recovery was 
not complete until four months after the operation. 
In young dogs, it is quite frequent to observe a deformity of the anterior 
legs, somewhat similar to the sprung knees of horses, an exaggeration of the 
flexion of the metacarpals upon the fore-arm, due to the retraction of the 
flexor tendons. This deformity may exist in one or both legs. Generally 
suscarpal tenotomy succeeds. With the straight tenotome, introduced un- 
der the external and oblique flexors of the metacarpus, these are divided. 
Sometimes the division of the perforatus is necessary (Peuch). A dressing 
with splints or pasteboard, extending from the lower end of the paw to 
the superior extremity of the fore-arm, will keep the bones in their proper 
position. After five or six days, the dressing can be takenoff; the wound 
is cicatrized. The straightening of the leg takes place gradually.

TENDINOUS HELMINTHIASIS. 
The veticulus spiroptére is found not only in connective tissue and 
arterial walls, but also in tendinous and ligamentous tissues. The cervical 
ligament, suspensory ligament, tendons of the perforans and perforatus 
seem to be the most affected. When these exist on the legs, they give 
rise to true tendinitis with lameness (Barrier, Mauri). Ordinarily the 
deformity and sensibility of the affected organ permit the diagnosis; but 
there are cases where those are missing. The horse mentioned by Mauri 
was very lame on the left fore leg; the knee was constantly flexed; by
