[Visualization of the scapholunate space. Description of a simple radiologic image]

Scapho-lunate diastasis is a radiologic criterium of carpal instability. This paper stresses on the importance of producing an X-ray beam that will be parallel to the scapho-lunate joint and describes a simple radiologic positioning that will be a useful complement to the standard views. This view could be associated with the usual static as well as dynamic radiographs.
