708 OPERATIONS ON THE FOOT. 



the tendinous sheaths, or even of the digital articulations. There 

 may also be a diffused gangrene with separation of the hoof and 

 purulent infiltration under the horny box — ^periostitis, and caries 

 of the cartilage. This is the deep tendinous quittor in the most 

 severe form. In this last case, especially if there is an accumula- 

 tion of pus ia the tendinous sheath, the tumor is very painful, the 

 slightest touch giving rise to the manifestation of extremely acute 

 suffering, the hoof beiag constantly raised from the ground. The 

 fever is violent, there is a complete anorexia, and the exercise of 

 all functions is more or less disturbed. The compulsory resting 

 upon the healthy legs may give rise to svreUing of the hocks, and 

 even to lamioitis. 



In cattle, tendinous quittor becomes more painful than in the 

 horse, and is always accompanied by a swelling which may extend 

 to the knee. Rumination stops, and the animal endures great an- 

 guish. The slough is followed by a wound of varying depth, which 

 often exposes the diseased articular surfaces of the phalanges. If 

 this remains too long, the pus may affect the interdigital ligament, 

 complicate the disease, and even make it incurable. In this case, 

 the amputation of one of the digits may sometimes be performed. 



II. Progress, Duration and Termination. — The duration is 

 generally protracted; the disease often gives rise to chronic lesions 

 difficult to remove. This will be easily understood, if we remem- 

 ber that the region affected is composed, between the skin and 

 the bones, of synovial capsules, ligaments, tendons and aponeu- 

 roses, more or less cellular tissue, and of very strong nervous 

 ramifications. If the disease is not very deeply seated or unilat- 

 eral, complete recovery may be looked for; but if there are 

 chronic lesions, if the articular surfaces become affected; espe- 

 cially if particles of bones are sloughing, if the animal recovers it 

 will be but imperfectly, and it wiU usually be accompanied by 

 anchylosis of the joint, and diffused gangrene is also a complica^ 

 tion to be looked for. 



III. Diagnosis. — We said at the beginning that tendinous 

 quittor is a very obscure disease; the lameness is very great, but 

 not characteristic ; in proceeding, we referred to the acute local 

 pains at the side of the tendinous cord of the cannon, the inflam- 

 matory swelling, the increase of local pains, and the general reac- 

 tive fever. 



IV. Prognosis. — It is a very serious disease, on account of
