Ruptures of flexor tendons at the wrist as a complication of fracture of the distal radius.

We report two cases of rupture of flexor tendons after fracture of the distal radius. The first case was a rupture of the flexor digitorum profundus and superficialis tendon to the index finger that happened 20 years after the fracture. The second was a rupture of the flexor pollicis longus tendon that occurred two years after, and the flexor profundus tendon to the index finger that occurred four years after the fracture. In the first case, the ruptures were caused by the bony protuberance of the radius after long interval without interference of the ulnar head.
