LAMENESS IN THE FORE LEG 93 



as in cases where skin is destroyed, the frequent (three or four 

 daily) application of a suitable antiseptic powder is necessary 

 to check exuberant granulation. This may be directly effected 

 by the use of an astringent or desiccant preparation, and such 

 dressing serves as a mechanical protection as well. 



When such wounds are kept clean, where drainage is properly 

 maintained, and the subject kept quiet, no particular attention 

 other than the local application of an astringent lotion (such 

 as the zinc and lead lotion) is necessary after the first three or 

 four weeks. Usually, if the animal gnaws at the parts or other- 

 wise manifests evidence of discomfort, it is an indication that 

 new areas of infection are being established because of obstructed 

 drainage or retained eschars. A thorough cleansing of the 

 wound with a two per cent solution of Liquor Cresolis Com- 

 positus and this followed by moistening every part of the wound 

 with tincture of iodin, will check all such disturbance if done 

 promptly. 



Where practically all of the anterior surface of the radius 

 has been denuded, recovery is tardy and there is in some cases 

 imperfect extension of the leg for months after the wound has 

 healed. But in such instances, animals gradually regain com- 

 plete use of the affected member and in the course of a year 

 function is fully restored. 



Inflammation and Contraction of the Carpal Flexors. 



Anatomy. — The structures w^hich are usually considered as 

 true flexors of the carpus are a group of three muscles, which 

 have separate heads of origin and different points of tendinous 

 insertion. 



The flexor carpiradialis (flexor metacarpi internus) originates 

 from the medial epicondyle of the humerus. It is inserted to 

 the proximal end of the medial metacarpal (inner metacarpal or 

 splint) bone. This muscle is the smaller of the three and is not 

 usually divided in doing carpal tenotomy. 



The flexor carpiulnaris (flexor metacarpi medius) has two 

 heads of origin ; one, the larger, originates from the epicondyle 

 of the humerus and the other from the posterior surface of the
