Flexor Superficialis Abductor Transfer With Carpal Tunnel Release for Thenar Palsy

Carpal tunnel release with simultaneous flexor digitorum superficialis-to-abductor pollicis brevis transfer provides satisfactory results for patients with profound CTS and thenar paralysis. The use of the small finger superficialis as the donor motor has minor morbidity compared with other methods and has predictable improvement and patient satisfaction. This transfer method is combined easily with endoscopic carpal tunnel release (as in 49 of our 51 cases), 2-portal, or open method releases.
