Avulsion injuries of the flexor digitorum profundus tendon can be with or without a bony fragment. Types 3, 4, and 5 injuries often have a sizeable bony fragment. In the past, they have been repaired with either a screw, plate, or pull-out wire with a dorsal button, often in combination with a K wire to immobilize the distal interphalangeal joint. We illustrate with 2 cases a simple technique for secure repair of the flexor digitorum profundus avulsions with a bony fragment. In contrast to previously described techniques, our technique involves minimal dissection, has a significantly reduced risk of fracture to the bony fragment, is completely internalized thereby reducing the risk of postoperative infection and allows immediate mobilization.
