The extensor apparatus of the fingers is a complex structure. The diagram of the extensor apparatus as seen in figure 1 is in reality not so clearly structured. Closed lesions are the mallet finger, where either an avulsion of the bony insertion of the tendon occurs or where a fracture of the base of the distal phalanx with dislocation of a bone-fragment together with the tendon insertion has happened. ⋯ In early cases by stretching the finger passively the lateral band will be repositioned. In these cases, a conservative treatment with a splint holding the PIP-joint in extension may be successful. This can be combined with revision and suturing of the ruptured part.(ABSTRACT TRUNCATED AT 250 WORDS)
