Acute multiple flexor tendon injury and carpal tunnel syndrome after open distal radius fracture.

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.
