694 OPERATIONS ON THE FOOT. 



the secretion of the coronary band was kept under control, but 

 not that of the podophyllous tissue. 



Generally in these cases the suppleness of the hoof must be 

 kept up by appropriate topics. It must be cut off when too thick, 

 and a shoe must be applied sufficiently wide in the web to protect 

 the anterior part of the sole as far as the point of the frog. This 

 shoe must be quite hollow on the foot surface, so as to avoid any 

 pressure upon the sole. It must be nailed on principally at the 

 heels, as nails at the toe would not hold sufficiently. Between the 

 shoe and the foot a piece of gutta percha, or felt or leather may 

 be put on. Thus shod, a horse will still do long service, even in 

 cities, and much more in the country. 



When there is a wound at the sole, with separation of the part, 

 suppuration, caries of the os pedis, which protrudes through the 

 sole, it is advised to have recourse to a surgical oj)eration. The 

 contents of the abscess under the sole must be evacuated, and the 

 sole thinned down in the entire plantar region. If the bone is 

 carious it is scraped, the necrosed parts are removed, and a proper 

 dressing, kept up by plates under the shoe, is jDut on. There are 

 a few cases where, by this treatment, horses have been enabled to 

 resume their work. 



Often in chronic laminitis when, notwithstanding the opera- 

 tion and the shoeing, the horse is unable to resume his work, ac- 

 cording to H. Bouley, the operation of neurotomy will then be 

 beneficial. Grad is not of the same opinion. He claims that the 

 relief is then uncertain and only temporary. Jessen and Hering 

 say that this operation is followed very often by the sloughing of 

 the hoof, and the animals stumble very easily. According to 

 Braull this operation is followed by a greater growth of the hoof. 

 If the lameness is reduced after the operation the deformity of 

 the foot continues to increase. 



Navicular Disease. 



Synonyms. — Chronische Hufgenklahme, German; Maladie 

 Namculaire, French. This disease, called by Loisel and H. 'S>ovl- 

 \e^, j)odosesmnoideal synovitis (synovite podosesamoidienne) ; by 

 Braull, chronic podotrochlitis, is an inflammation of the sesamoid 

 sheath of the horse, that Turner and some other English veterin- 

 arians were the first to describe, and which is mostly observed in 

 thoroughbreds.
