Cubital tunnel syndrome can present with pain/numbness in the ulnar nerve territory and weakness in the ulnar-innervated extrinsic/intrinsic muscles. The etiology for cubital tunnel syndrome depends on the case and includes various points of compression along the course of the ulnar nerve. The most common compression point is the medial epicondyle at which the fascial leading-edge of the flexor carpi ulnaris and the aponeurosis superficial to the cubital tunnel compress the nerve. However other compressive points can exist and can be under-recognized. The transmuscular ulnar nerve transposition (TUNT) addresses these compressive points by releasing and transposing the nerve through a transmuscular bed within the pronator-flexor muscle bundle. In this case, the patient had a traumatic medial cord injury and presented 1-year following with associated ulnar neuropathy and fibrillations/motor unit potentials. The TUNT was elected with a supercharge anterior interosseous to ulnar motor nerve transfer, Guyon's canal release, and FDP tenodesis. This video highlights details of the TUNT.
