Concurrent flexor carpi radialis tendon rupture and closed distal radius fracture.

Tendon rupture as a complication of distal radius fractures has been documented; however, flexor tendon rupture associated with closed distal radius fractures is rare. We report a case of a 43-year-old man who suffered a closed distal radius fracture. Intraoperatively, it was discovered that the flexor carpi radialis tendon had ruptured. From the frayed ends of the tendon and review of the radiographs, it was determined that the sharp ends of the fractured radius had lacerated the tendon at the time of injury. After fixation of the fracture with locking plate, the severed tendon was repaired and the wrist immobilised with a splint. The patient has been pain free after 5 months of follow-up, with full range of motion. This outcome demonstrates that timely detection and treatment of concurrent flexor carpi radialis tendon rupture and a closed distal radius fracture can achieve good functional results and outcome.
