Avulsion of flexor profundus, secondary to enchondroma of the distal phalanx.

Avulsion injury of the profundus tendon secondary to enchondroma of the distal phalanx is extremely rare. A case is described in which the enchondroma cavity was filled with an iliac bone graft and the avulsed fragment attached to the bone graft and the distal phalanx with a bone screw. Full function of the digit was regained.
