Scapholunate dissociation is the most common form of instability of the wrist. Its occurrence has been consistently attributed to previous trauma and is supposed to be treated by operation. In the present paper we show that chronic bilateral scapholunate dissociation without any symptoms is not rare. In two years we accidently found four cases with bilateral scapholunate dissociation. In such cases an operation cannot be successful. Therefore, we recommend that a specific trauma should be checked very carefully and roentgenograms of both wrists done.
