[p. 205]extension at the wrist, and another grasping the armpit,
while a third, applying the palm of his hand to the part of the joint
which is displaced, pushes it inward, and at the same time makes
counterpressure on the opposite side near the joint with the other
hand.
Part 40
The end of the humerus at the elbow gets displaced (subluxated?)
by leaving the cavity of the ulna. Such luxations readily yield to
reduction, if applied before the parts get inflamed. The displacement
for the most part is to the inside, but sometimes to the outside,
and they are readily recognized by the shape of the limb. And often
such luxations are reduced without any powerful extension. In dislocations
inward, the joint is to be pushed into its place, while the fore-arm
is brought round to a state of pronation. Such are most of the dislocations
at the elbow.
Part 41
But if the articular extremity of the humerus be carried to either
side above the bone of the fore-arm, which is prominent, into the
hollow of the arm (?), this rarely happens; but if it does happen,
extension in the straight line is not so proper under such circumstances;
for in such a mode of extension, the process of the ulna (olecranon?)
prevents the bone of the arm (humerus?) from passing over it. In dislocations
of this kind, extension should be made in the manner described when
treating of the bandaging of fractured bones of the arm, extension
being made upward at the armpit, while the parts at the elbow are
pushed downward, for in this manner can the humerus be most readily
raised above its cavity; and when so raised, the reduction is easy
with the palms of the hand, the one being applied so as to make pressure
on the protuberant part of the arm, and the other making counter-pressure,
so as to push the bone of the fore-arm into the joint. This method
answers with both cases. And perhaps this is the most suitable mode
of reduction in such a case of dislocation. The parts may be reduced
by extension in a straight line, but less readily than thus.
Part 42
If the arm be dislocated forward- this rarely happens, indeed, but
what would a sudden shock not displace? for many other things are
removed from their proper place, notwith-
