Abstract

A 20-year-old right-handed fisherman experienced a severe injury in a high-energy traffic accident. These injuries included a shaft fracture of the right humerus, open comminuted fracture of the right forearm and multiple peripheral nerve palsies involving the musculocutaneous, median and radial nerves. Six months after the initial treatment, the patient was referred to our hand surgeons for further treatment. Several operations for functional reconstruction using only the ulnar nerve and ulnar nerve-innervated muscles were performed: the main procedures included a partial ulnar nerve transfer for elbow flexion, flexor carpi ulnaris transfer for reconstruction of wrist and finger extension and opponensplasty using the abductor digiti minimi. Three years after the initial injury, the patient had relatively good function including elbow flexion and stable side pinch and grasp. Functional reconstruction using a combination of the ulnar nerve and ulnar nerve-innervated muscles may be useful in specific cases involving multiple peripheral nerve injuries.
