Abstract
A mechanical device has been developed for artificial elbow flexion. It consists of a brace for the complete upper extremity, including the shoulder and the hand. The shoulder support is kept in place by means of a strap around the chest and under the opposite axilla. The hand mechanism, which appears fixed in the photograph, has been made movable at the wrist, so that the hand can be fixed in the pronated position or in the mid position by adjusting a screw at the wrist portion of the brace. The patient is able to flex the elbow at any desired position by swinging the arm forward. The elbow joint has several stops in flexion, with a release lever on the outside of the forearm. The hand may be turned into pronation or mid position by releasing screw catch at the wrist. The functional benefits of this device are as follows:
