[Rehabilitation of extensor tendon injuries].

The extensor mechanism of the hand consists of different tendons, originating from extrinsic and intrinsic muscles of the hand and forearm. Because of their course near to skin and bone separated only by a thin layer of paratenon, they are very sensitive to injuries and adhesions. Treatment protocols have to be adapted according to the different zones. This paper explains the basic principles of rehabilitation in extensor tendon injuries.
