Verletzungen der Endgelenke

Abstract

Injuries of the distal interphalangeal joints mostly involve the extensor tendon. Its superficial position on the dorsal aspect of the finger often exposes the extensor tendon to closed and open injuries. Lesions of the extensor tendons are more common than those of the flexor tendons. Furthermore, injuries of the joint often occur as fractures of the dorsal base of the distal phalanx, and, less frequently, as fractures of the head of the middle phalanx. In all cases, correct diagnosis and therapy is essential. Incorrect diagnosis and neglecting of the injury by both surgeon and patient often lead to considerable complications, e.g., delayed healing and lack of function.
