[Significance of primary diagnosis in dislocations of the carpal bones].

In order to diagnose dislocation of carpal bones it is important to interpret the X-ray film correctly. In most cases of primary dislocations, closed anatomical reduction can be achieved. The resulting stability after primary reduction must be checked in moving the wrist under X-ray intensifier control. If there is reluxation or any persisting instability, operative treatment is indicated. By clinical examples it is shown that very good functional results are obtained after primary diagnosis and correct treatment. Regarding overlooked dislocation of carpal bones, therapeutic management is difficult and the clinical result is often unsatisfactory.
