Extensor tendon injuries of the hand

The treatment of extensor tendon injuries of the hand is based on Verdan's division of the different sections into eight zones. Taking the anatomic characteristics of those zones into consideration, good functional results can be achieved in most cases by differentiating between indications for operative or conservative treatment. The most frequent extensor tendon injury of the hand is the closed tendon rupture over the DIP joint. In almost all cases it can be completely cured by immobilization for at least 8 weeks. Open extensor tendon injuries on the other hand require surgical therapy. This paper gives a clearly arranged overview of the different therapeutic options.
