Anterior Interosseous to Ulnar Motor Supercharge Nerve Transfer

The supercharge nerve transfer is a procedure that coapts the distal end of a donor nerve to the side of the recipient nerve. Nerve regeneration is facilitated from donor to recipient through a perineurial window to enhance regeneration from the proximal regenerating nerve. This procedure can be used in cases of 2nd/3rd degree nerve injuries to augment motor recovery, with the advantages of a nerve transfer and without sacrificing the integrity and proximal regeneration of the recipient nerve. In this case, the patient had an iatrogenic medial cord injury. She presented 7 months following injury with ulnar intrinsic atrophy and fibrillations/motor unit potentials in her ulnar extrinsic/intrinsic muscles. The supercharge anterior interosseous to ulnar motor nerve transfer was elected with a transmuscular ulnar nerve transposition, Guyon’s canal release, and FDP tenodesis. This video highlights details of the supercharge nerve transfer, with specifics on the perineurial coaptation, Guyon’s canal release, and FDP tenodesis.
