ons of suitable
antiseptics. After a week or ten days' time, the wound should not be
dressed more frequently than twice weekly.
If it is necessary to leave a portion of the wound uncovered, 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 otherwise 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 Compositus 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 complete 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 which 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 olecranon. The two
heads unite at the upper third of the radius and the muscle, becoming
tendinous, as is the case with the other carpal flexors, is attached by
one point of insertion t
