ABSTRACT:
A shoulder, forearm, wrist and hand support is disclosed which is formed of rigid material and includes a semi-circular forearm supporting portion shaped to encompass and to exert a constant pressure on the volar surface of the forearm and to provide an edge extending laterally shaped to wrap around and support the ulna, a wrist supporting portion shaped to fit against the inner or volar surface of the wrist and support the wrist in a position of from about 9.degree. to about 21.degree. hyperextension, a hand supporting portion being shaped to fit against the volar surface of the hand, fingers and thumb, and to support the metacarpal-phalangeal joint in a position from about 14.degree. to about 26.degree. flexion, to support the proximal and distal interphalangeal joints in full extension and to hold the thumb in a position from about 29.degree. to about 41.degree. abduction and apposition. A strap fits snugly about the hand supporting portion and hand at the metacarpal joints thereby supporting the palmar arch, and an elastic strap having its ends secured adjacent each end of the forearm supporting portion extends over the chest, around the neck and back of the patient. The shoulder, forearm, wrist and hand are thus held in a normal position, that is, the forearm is neither pronated nor supinated, and the shoulder and elbow are free to move.
