Case 1. a There was severe damage to the musculocutaneous nerve, and a primary suture or graft was deemed impossible. b The distal muscle flap of the transferred llatissimus dorsi muscle was divided into two. c Simple X-ray imaging shows fixation to the radial and ulnar tuberosities with GII^® anchors. d Elbow flexion and soft tissue were simultaneously reconstructed with a latissimus dorsi musculocutaneous flap. e Elbow’s active range of motion was 10–145°. f Forearm pronation was performed with extension resistance. Active contraction of the latissimus dorsi muscle with elbow flexion was confirmed (Yellow triangles indicate latissimus dorsi muscle). g Active contraction of the latissimus dorsi muscle was confirmed similarly to forearm supination (Yellow triangles indicate latissimus dorsi muscle)
