Rupture of flexor tendons as a complication of a distal radius fracture.

Two cases are reported of flexor tendon rupture of ulnar side fingers as a complication after distal radius fracture. One was associated with a prominent distal volar lip of fracture site, the other with a relatively volarly displaced ulnar head due to the dorsally tilted distal radius due to malunion. These may be unique cases of flexor tendon rupture with conservatively treated patients.
