[Subcutaneous avulsion of the flexor digitorum profundus and flexor digitorum superficialis tendons of the ring and little fingers caused by blast injury].

The authors report a case of subcutaneous avulsion of flexor profundus and flexor superficialis tendons of the ring and little finger, caused by a blast injury. Treatment consisted of excision of the flexor superficialis tendon with transosseous reinsertion of the flexor profundus tendon. The functional result was good. Subcutaneous traumatic rupture of flexor tendons occurs infrequently, but simultaneous rupture of both flexor tendons is extremely rare. Knowledge of the subject is limited and treatment of this disorder is poorly defined.
