to support weight with
the affected member even when it is passively placed in position.

No difficulty is ordinarily experienced in differentiating radial
paralysis from muscular injuries to the triceps; yet, in some cases of
"dropped elbow," it is necessary to observe the progress of the case for
ten days or two weeks before one can positively establish a diagnosis.

Quoting Merillat[12]: "When, after four weeks, there is no
amelioration of the paralysis, the muscles have atrophied, and the
patient has become emaciated from pain and discomfort, the
diagnosis of brachial paralysis with fracture of the first rib may
then be announced."

Prognosis.--When no complete paralysis of the brachial plexus or no
fracture of the first rib exists, the majority of cases recover
completely in from ten days to six weeks. Some writers claim that
recoveries occur in ninety per cent of cases when conditions are
favorable.

Treatment.--When incomplete radial paralysis exists, little needs be
done except to allow the subject moderate exercise and to provide for
its comfort. Local applications, stimulative in character, are
beneficial, and the internal administration of strychnin is indicated.

In the cases where weight is not supported without the affected leg
being passively placed in position, it is necessary to provide for the
subject's comfort in several ways.

Mechanical appliances such as braces of some kind in order to keep the
affected leg in a position of carpal extension, constitute the essential
part of treatment. The leg is supported in such a manner that flexion of
the carpus is impossible. Due regard is given to prevent chafing or
pressure necrosis by contact of the skin with the braces--this may be
done by bandaging with cotton. The supportive appliance is kept in
position for ten days or two weeks. At the end of this time the brace
may be removed and the subject given a chance to walk, and improvement,
if any exists, will be evident. When there is manifested an amelioration
of the condition, moderate daily exercise and massage of the affected
parts are helpful.

Should the subject be seriously inconvenienced by the application of a
brace or other supportive appliances, it is necessary to employ slings.
Further, if weight is supported entirely by the unaffected member,
laminitis may supervene if a sling is not used.
