This ajDplies to thecongenital as well as to the acquired disability.

The shoulder is grasped firmly with one hand inorder to restrain the movements of the scapula, and with theother the arm is drawn upward and backward over the fulcrumof the thumb, which lies behindthe joint. This, the so-calledpump-handle movement, alter-nately relaxing and stretchingthe contracted parts, is carried outover and over again with slowlyincreasing force, the aim beingto force the head of the bone for-ward, and thus to thoroughlystretch the anterior part of thecapsule. When this has beenaccomplished, there is a distinctdepression behind, and the headof the humerus j)rojects in front,at a point below its proper posi-tion. One then attempts to over-come the abduction and to forcethe head
