[Functional therapy and the limitations for acute elbow dislocation].

Dislocation of the elbow joint is the second most common dislocation, the shoulder being the most common. Non-surgical therapy is done by repositioning and early active motion after a short period of immobilization. There are, however, certain principles which must be followed in order to obtain a favorable result with functional therapy. On the basis of case reports the constraints of early active motion are discussed. Knowing the mechanism or kinematics of an elbow dislocation, it is possible to determine a staging of the injury. Using detailed x-rays and an exact stability test, the degree of instability must be checked after repositioning. It is important to determine the grade of instability and to operatively correct a major instability.
