[X-ray diagnosis of ruptures of the distal radioulnar joint].

The paper describes 42 intact, 14 damaged and 52 ruptured radioulnar joints. The joints width was measured, the radioulnar index calculated, x-ray pictures filtered. Variants of isolated injuries of the joints in different bone dislocation, changes in combined ruptures and injuries are described. The radioulnar index proved the best in quantitation of the joint damage.
