ABSTRACT:
An arm sling includes a semi-rigid trough which partially encircles and supports a patient's forearm, wrist, and hand. A yoke is connected to the sides of the trough at a location away from the distal end. An adjustable-length strap extends upward from the yoke over the front of the patient's ipsilateral shoulder, diagonally across the patient's back, and transversly across the front of the patient's body to an attachment point on the trough near the patient's elbow. An elbow piece adjustably fixed to the trough accommodates various elbow angles and arm widths. The yoke supports the patient's forearm, wrist, and hand in a cantilevered fashion at various elevations, while not interfering appreciably with lateral movement of the distal end of the trough and rotation of the patient's upper arm at the shoulder joint.
