46 DISEASES OF THE DOMESTIC ANIMALS 



into the sac by means of a hypodermic syringe connected with the 

 needle which has been previously inserted. The sac must be manip- 

 ulated so that the injection will come in contact with all parts of it. 

 Collodion is employed to seal the puncture of the aspirator needle. 

 Considerable local inflammation will follow and is relieved by the use 

 of a wet dressing (2 per cent, creolin) kept constantly on the part. 

 Absolute rest for some time must be enforced. If this treatment 

 prove unsuccessful, or in any case, incision of the cyst, thorough 

 curettage, packing of the cavity with aseptic gauze soaked in hydro- 

 gen dioxide, and the external application of a dressing wet with 

 2 per cent, creolin solution may be done. The wet dressing should 

 be employed during the healing process. The actual cautery may 

 be used to open and destroy the wall of the cyst, but is not to be 

 preferred to knife and curette. Complete excision of the mass with 

 the bursa is the only remedy for a greatly indurated bursal mass. 

 First intention is, however, very hard to secure. (See also Teno- 

 synovitis, p. 244.) 



When the fibrous enlargement has a distinct pedicle then elastic 

 ligature may be employed, as in shoe ball in some cases. If the 

 ligature has a tendency to slip it may be held in place by a transfixion 

 pin or suture. Excision is, however, more rapid and precise. 



Navicular disease is treated by the application of cold swabs 

 kept constantly wet about the coronet of the affected foot or feet, 

 by the use of poultices, or by causing the animal to stand in warm 

 water. Later, blister of the coronet and the use of shoes thick at 

 the heels and thin at the toe and the employment of rubber pads 

 may relieve the lameness. Neurectomy above the fetlock is the 

 last resort. 



Tuberculous bursitis can not be cured except by complete 

 excision, but this is rarely worth while in cattle. 



Inflammation of bursae under the flexor brachii in the 

 bicipital groove; and at the external tuberosity of the humerus
