Accessory flexor pollicis longus tendon – a clinical and cadaveric study

Abstract

An accessory flexor pollicis longus tendon was found in 25 of the 53 patients who underwent trigger thumb release, as well as in two of five randomly selected cadaveric thumbs. Cadaveric and histopathologic analyses confirmed these variants. Their anatomical, clinical and evolutionary significance is discussed.
