Although the rupture of extensor tendons after distal radius fractures is well 
described, acute flexor tendon ruptures are much less common. We report a case 
of acute rupture of the flexor pollicis longus and flexor carpi radialis tendons 
with acute carpal tunnel syndrome after a Gustilo-Anderson type II open distal 
radius fracture. We reviewed the literature to identify risk factors for tendon 
rupture and the development of carpal tunnel syndrome.
