Case:
Flexor digitorum profundus avulsions are common injuries that manifest as tendinous or bony avulsions from the distal phalanx. Rarely, additional fractures can occur in the distal phalanx. For such injuries, repair of the avulsion and fracture is recommended but difficult because of limited bone stock for fixation.
Conclusion:
We present a case of a 28-year-old man with a combined flexor digitorum profundus bony avulsion and bony mallet finger, and describe a strategic fixation technique using an intramedullary suture anchor and dorsal button that provided stable fixation and resulted in excellent motion and function, with return to sport at 12 weeks.
