Abstract
Extensor pollicis longus tendon rupture is well known as a complication of fracture of the distal radius. There is a higher risk that the tendon of extensor pollicis longus will rupture in undisplaced distal radius fracture than in those which are displaced. This difference in incidence is due to the integrity of the extensor retinaculum in undisplaced distal radius fracture causing the tendon to be held tight against the fracture callus in the floor of the tunnel which may result in an attrition rupture. In the displaced distal radius fracture the extensor retinaculum is torn from the bone and thus permits the tendon to escape from contact with the fracture site. Early disruption of the extensor pollicis longus tendon as a complication of undisplaced distal radius fracture is not common. We have experienced one case of early disruption of the extensor pollicis longus tendon after undisplaced distal radius fracture. It was treated by end-to-end anastomosis. After initial trauma of the distal radius fracture, careful evaluation of extensor pollicis longus tendon was needed.
