A reported case of postoperative bilateral brachial plexus neurapraxia associated with the use of a Canadian frame in a patient who had thoracolumbar spinal surgery under general anesthesia. Symmetrical misposition of the upper pads of the Canadian frame underneath both shoulder heads during prolonged surgery led to direct compression on or stretching of the bilateral brachial plexus. This complication should be prevented by carefully placing the patient on this sort of frame.
