520 VETERINARY SURGICAL’ THERAPFITICG, 
In bovines, luxation of the fetlock is rare. Few observations only‘ 
have been recorded. The three cases related by Strebel were heifers, 
aged from fifteen months to two years. Each time the injury consisted 
in an overlapping of the inside suffraginis on the metacarpal. The re- 
duction was performed standing or with the animal down. In these three 
cases, perfect recovery followed the application of a contentive band- 
age. 
XI.—Phalangeal Articulations. 
Luxations of phalanges are exceptional. United by strong ligaments. 
and consolidated in their relation by very powerful tendons, phalanges. 
are very little exposed to extensive and permanent displacements, 
Only very rare examples are published, all of the greatest severity. 
The case of Johne relates to a luxation of the third phalanx ; the lower 
extremity of the os corone overlapped the small sesamoid backwards, 
the articular ligaments and the perforans were lacerated. 
If treatment is to be undertaken, reduction and immobilization are 
indicated, as for the other luxations. Bandages recommended for 
phalangeal fractures would be useful here. 
XIT.— Pseudo Luxation of the Patella. 
Solipeds and bovines are subject to a special and typical lameness 
of the hind leg, due to the patella becoming, so to speak, hooked by the 
summit of the femoral pulley. If the animal is made to walk ahead,. 
the affected leg cannot be carried forward, but remains extended, 
obliquely downwards and backwards; any flexion is impossible, and. 
when the animal moves, the anterior face of the hoof drags on the 
ground. Most minute exploration of the leg reveals only a slight 
tension of the muscles and a slight deviation of the patella outwards. 
These symptoms, however, disappear as rapidly as they occur; it is not’ 
rare after a few minutes’ walk, or even after a few seconds, to see the; 
various joints of the leg flex upon each other, first spasmodically, as in. 
stringhalt, and then normally. And ordinarily the return of the trouble: 
takes place without apparent cause. 
These symptoms have received various interpretations. Solleysel,. 
Garsault, Lafosse, saw in them nothing but a“ cramp’’; for Vitet, it was. 
a temporary spasm accompanied with pains. Pastureau explained them 
by the arrest of the internal femoro-patellar ligament over the correspond-. 
ing lip of the femoral trochlea. The great majority of authors have 
described this accident under the name of “ luxation of the patella.” But. 
this last is very rare, and cannot occur without the laceration of one of 
the little femoropatellar ligaments.
