The more ordinary method consists in putting the patient on his back on the floor, the operator also sitting on the floor with his stockinged foot against the patient's side under the armpit of the injured shoulder and grasping the injured arm at the elbow, he pulls the arm directly outward (i. e., with the arm at right angles with the body) and away from the trunk. An assistant may at the same time aid by lifting the head of the arm bone upward with his fingers in the patient's armpit and his thumbs over the injured shoulder.

If the arm does not go into place easily by one of these methods it is unwise to continue making further attempts. Also if the shoulder has been dislocated several days, or if the patient is very muscular, it will generally be necessary that a surgeon give ether in order to reduce the dislocation. It is entirely possible for a skillful surgeon to secure reduction of a dislocation of the shoulder several weeks after its occurrence. After the dislocation has been relieved the arm, above the elbow, should be bandaged to the side of the chest and the hand of the injured side carried in a sling for ten days.

DISLOCATION OF THE ELBOW.—This is more frequent in children, and is usually produced by a fall on the outstretched hand. The elbow is thrown out of joint, so that the forearm is displaced backward on the arm, in the more usual form of dislocation. The elbow joint is swollen and generally held slightly bent, but cannot be moved to any extent without great pain. The tip of the elbow projects at the back of the joint more than usual, while at the front of the arm the distance between the wrist and the bend of the elbow is less than that of the sound arm. (See cut, p. [126].)

DISLOCATED ELBOW AND SHOULDER.

(American Text-Book.)

Fig. 32 shows dislocation of elbow backward; note swollen condition of left elbow held slightly bent; also the projection of back of joint.

For further proof that the elbow is out of joint we must compare the relations of three points in each elbow. These are the two bony prominences on each side of the joint (belonging to the bone of the arm above the elbow) and the bony prominence that forms the tip of the elbow which belongs to the bone of the forearm.
