A 35-year-old man underwent plastic surgery for pyoderma at his axillary fossa in the right lateral decubitus position. Immediately after emergence from anesthesia, the patient complained of motor and sensory disturbance in his left upper extremity and was diagnosed with brachial plexus injury by magnetic resonance imaging（MRI）. This injury might have been caused by nerve compression or blood supply interruption resulting from prolonged inappropriate positioning of the upper extremity during surgery. Anesthesiologists should keep in mind the risk of nerve injury associated with unusual surgical positioning for long periods and prevent it by preoperative planning and meticulous observation during surgery.
