Two forms of true patellar luxation in the horse may be considered; one which is due to the patella becoming fixed upon the internal trochlear rim of the femur and the other when the patella slips over the outer rim of the trochlea. According to Cadiot and Almy, it is only by the rupture of this ligament the femeropatellar that upward luxation may occur.
Occasionally one may observe in suckling colts outward luxation of the patella wherein there is history of navel infection and no marked evidence of rachitis is present. Some of these cases recover.
It is firmly fixed to the tibia at each end, and is commonly spoken of as the small bone of the leg. Its lower end forms the outer projection of the ankle. In front of the knee joint, embedded in a thick, strong tendon, is an irregularly disk-shaped bone, the patella, or knee-cap.
In cases of habitual luxation, unless the ligaments are so lax that the patella may be displaced laterally over the inner as well as the outer trochler rims, division of the inner straight patellar ligament will correct the condition. This desmotomy has been advocated by Bassi, and good results in appropriate cases have been reported by Cadiot, Merillat and Schumacher.
While riding in a field in a violent storm, a loud peal of thunder caused the horse to run away, and the child fell stunned to the ground. On coming to his senses the boy found that his right leg was missing, the parts having been divided at the upper end of the tibia. The wound was perfectly round and the patella and femur were intact.
This operation has been found a corrective in cases of outward luxation as well as those of upward dislocation of the patella when resorted to before the trochleae are worn from frequent luxation.
Now Patella was the youngest of the company, a modest man, filled with a profound reverence for the science of Cuticle, and desirous of gaining his good opinion, yet not wishing to commit himself altogether by a decided reply, though, like Surgeon Sawyer, in his own mind he might have been clearly against the operation. "What you have remarked, Mr.
Let it be borne in mind that 'Avicula', 'Mytails', 'Chiton', 'Natica', 'Patella', 'Trochus', 'Discina', 'Orbicula', 'Lingula', 'Rhynchonella', and 'Nautilus', all of which are existing 'genera', are given without a doubt as Silurian in the last edition of 'Siluria'; while the highest forms of the highest Cephalopods are represented in the Lias by a genus, 'Belemnoteuthis', which presents the closest relation to the existing 'Loligo'.
If little inflammation exists, the application of a vesicant two or three weeks after the injury has been inflicted will be helpful and serve to hasten repair. Bandages or mechanical appliances are of no practical use in the handling of these cases. Luxation of the Patella. Etiology and Occurrence.
Every bone was in its natural place, the femur, tibia, fibula, ankle-bone, or astragalus, all in juxtaposition. Even the patella or detached bone of the knee-pan was searched for, and not in vain.
