Flexor Digitorum Profundus (FDP) Avulsion
Introduction
Flexor digitorum profundus avulsion generally occurs at the tendon's insertion at the distal phalanx. The injured finger cannot actively be flexed at the distal interphalangeal joint. X-rays are needed to rule out avulsion fracture. Treatment is with surgery. The injury occurs primarily in football and other contact sports (eg, rugby). The ring finger is the most injured (75% of cases). (See also Mallet Finger .)
