The joint of the hand is dislocated inward or outward, but most frequently
inward. The symptoms are easily recognized; if inward, the patient
cannot at all bend his fingers, but if outward, he cannot extend them.
Reduction:-By placing the fingers above a table, extension and counter-extension
are to be made by assistance, while, with the palm of the hand or
the heel on the projecting bone, one presses forward, and from behind,
upon the other bone, and lays some soft substance on it; and, if the
dislocation be above, the hand is to be turned into a state of pronation;
or, if backward, into a state of supination. The treatment is to be
conducted with bandages.
