Dislocations backward are to be rectified with the palms of the hands along with sudden extension. These two acts are to be performed together, as in other cases of the kind. In dislocation forward, the arm is to bend around a ball of cloth, of proper size, and at the same time replaced.
14
If the displacement be on the other side both these operations are to be performed in effecting the adjustment of the arm. With regard to the treatment,-the position and the bandaging are the same as in the other cases. For all these cases may be reduced by ordinary distention.

With regard to the modes of reduction, some act upon the principle of carrying the one piece of bone over the other, some by extension, and some by rotation: these last consist in rapidly turning the arm to this side and that.

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.
