Abstract
This case report describes the unusual occurrence of a flexor digitorum profundus avulsion secondary to an enchondroma of the distal phalanx of the middle finger. The enchondroma was treated by simple curettage with an autogenous bone graft harvested from the olecranon. The avulsed bone fragment was reattached to the distal phalanx using the pull-out suture technique. Bony union and full function of the digit were achieved.

Figure 3
(A) Flexor digitorum profundus (FDP) tendon had been avulsed at its insertion. (B) After curettage and bone graft insertion, the FDP was reinserted on the grafted bone using the pull-out suture technique. (C) Immediate postoperative lateral X-ray shows the pull-out button on top of the nail plate.
