Abstract :
Congenital absence of flexor pollicis longus without associated anomalies is a rare cause of inability to flex the inter-phalangeal (IP) joint of the thumb. Other causes are: anomalous insertion of flexor pollicis longus (FPL), congenital tenovaginitis of the flexor tendon sheath, partial anterior interosseous nerve paralysis, traumatic rupture of FPL and anomalous bands connecting tendons.
