Case 2. a Functions of the musculocutaneous nerve and biceps brachii were partially lost due to debridement. b The latissimus dorsi muscle flap was stretched to its original length and divided into two (Black squares indicate flaps). c The site of soft tissue loss was covered by the transferred latissimus dorsi musculocutaneous flap. d Latissimus dorsi muscle contraction was confirmed using electrical stimulation of the thoracodorsal nerve. e Elbow joint active range of motion was 20–130°. f Forearm pronation with extension resistance. Active contraction of the latissimus dorsi muscle during flexion was confirmed. g Active contraction of the latissimus dorsi muscle during flexion was confirmed with forearm supination
