RESUMEN
This study describes a case of flexor pollicis longus rupture resulting from long-term scaphoid nonunion advanced collapse. The tendon rupture mechanism was attrition due to sharp bone protuberances from the scaphoid in the carpal tunnel. Although this extremely rare complication has already been reported in the literature, our study is original in showing that proximal row carpectomy with consequent wrist shortening allowed primary tendon repair without transferring the flexor digitorum superficialis tendon of the ring finger or grafting the palmaris longus tendon, which besides using two-level suturing, interposes a non-vascularized tissue.

An anatomical variant of flexor digitorum superficialis brevis is an uncommon condition that may be a pitfall in diagnosing carpal tunnel syndrome, involving palpable mass and even characteristic symptoms. We present an unusual case of bilateral symptomatic carpal tunnel syndrome related to the presence of a flexor digitorum superficialis brevis muscle of the little finger, and a critical review of the literature.
