Avulsion Injuries of the Flexor Digitorum Profundus Tendon.
Avulsion fracture of the flexor digitorum profundus tendon (Jersey finger) is an uncommon injury. This injury involves mainly young and active patients, especially during sports activities. It is.L eddy and packer 1 classified flexor digitorum profundus (FDP) tendon avulsion injury into 3 types. A fourth category of injury (type IV avulsion) was described by Smith. 2 In type III avulsion, a bone fragment is attached to the avulsed tendon stump. There are many methods for repair of FDP tendon avulsion injury. 3 The pullout suture technique, 4 in which a transosseous pullout wire suture.Avulsions of the flexor digitorum profundus tendon may involve tendon retraction into the palm and fractures of the distal phalanx. Although various repair techniques have been described, none has emerged as superior to others. Review of the literature does provide evidence-based premises for treatment: multi-strand repairs perform better.
Loss of flexion of the distal interphalangeal (DIP) joint may occur owing to avulsion of the flexor digitorum profundus (FDP) from its insertion into the distal phalanx. Typical etiology is forced extension of the flexed finger, typically when tackling an opponent in football, which is often called “jersey finger.”.Clinical outcomes of repair and rehabilitation of the flexor digitorum profundus (FDP) tendon after avulsion injury remain unpredictable, presumably because of delay in diagnosis and associated time-dependent changes within the muscle and tendon.
Ring avulsion and prognosis injuries: Classification Fifty-five cases of ring avulsion injury were reviewed to examine how extent of injury and surgical management correlated with results. After injury, three patients had adequate circulation. Of 52 patients with inadequate circulation, 8 had primary amputation; salvage was attempted in - 44.
