Summary: A pedicled latissimus dorsi (LD) myocutaneous flap is a reliable reconstructive method for elbow flexion, though there are no reports regarding its application to a terminal nerve level injury of the brachial plexus. A 29-year-old man presented with dysfunction of elbow flexion, wrist extension, and finger extension. Physical examination and electromyography showed that the palsy was caused by an injury at the terminal nerve level of the brachial plexus without dysfunction of the axillary nerve. Bipolar transfer of LD for reconstruction of elbow flexion and subsequent tendon transfer for wrist and finger extension were performed. The final British Medical Research Council grade was 4 for elbow flexion, and active range of motion was 0/135. An injury at the terminal nerve level of the brachial plexus should be listed in the differential diagnosis of elbow flexion dysfunction even if shoulder function is intact, and a suitable reconstructive method for this atypical type of palsy could be bipolar transfer of a LD flap.
