Mallet finger

In the adult, mallet injury commonly occurs as either a soft tissue injury, less often associated with a dorsal avulsion fracture. It arises from the combination of an external flexion force on the distal interphalangeal joint at the same time as attempted extension of this joint, with tissue failure occurring at the extensor tendon insertion (Fig. 17).
