[Unusual rupture of a flexor profundus tendon in a rock climber].

Injuries of the flexor pulleys are common in rock climbers. Ruptures of the flexor profundus tendons are less common and take place almost exclusively in zone I at the level of the distal phalangeal insertion of the tendon. We report the case of a 48 years old rock climber who sustained an uncommon complete rupture of the flexor profundus tendon of the long finger during a monodigital grip. The tear was localized in zone III, immediately distal to the distal edge of the carpal tunnel. Tendon repair by direct suture followed by early active mobilization led to a satisfactory result. To the best of our knowledge, this is the first description of this type of injury in a rock climber.
