LAMENESS IN THE HIND LEG 253 



by thoroughly cleansing and painting with tincture of iodin, the 

 capsule is incised with a bistoury. An incision about an inch 

 in length, situated low enough to provide drainage, is made 

 through the tissues and the contents are evacuated. Tincture 

 of iodin is injected into the cavity and the parts are covered 

 with cotton and bandaged. No after-care is necessary except to 

 retain the dressing in position, which is not difficult in the 

 average case if the subject is kept tied. If much resistance is 

 exhibited, such as extreme flexion of the bandaged hock, the 

 animal may be put in a sling and little if any objection to the 

 bandage will be offered thereafter. The wound may be dressed 

 at the end of forty-eight hours and no redressing will be neces- 

 sary in the average instance if infection is not present. But 

 slight local disturbance and little distress to the subject result 

 in cases so treated even when infection occurs, but a good technic 

 is possible of execution in most instances and no infection should 

 take place. 



The surgical wound heals in two or three weeks and inflamma- 

 tion gradually subsides. Bandages are retained one or two 

 weeks, as the case may require, and subsequently a good wound 

 lotion may be employed several times daily. A good lotion for 

 such cases as well as in many others has long been employed 

 with success by Dr. A. Trickett of Kansas City. It consists of 

 approximately equal parts of glycerin, alcohol and distilled ex- 

 tract of witch hazel, to which is added liquor cresolis compositus, 

 two percent, and coloring matter q. s. 



Complete resolution does not occur in the average case. There 

 remains some hyperplastic tissue and even where the enlarge- 

 ment is slight, the prominent situation of the affection precludes 

 its being unnoticed. 



In disease of the flexor tendon and its bursa where contiguous 

 inflammation of tissue is present, the parts are blistered or fired. 

 Line firing is beneficial in such instances but in all cases the 

 cause is to be removed if possible.
