[On the roentgenologic observation of wrist flexion (author's transl)].
To analyze adduction (ulnar flexion) or abduction (radial flexion) at the wrist, a simple calculatory method is described (quitient from the length of the scaphoid bone--navicular bone or os scaphoideum--in radial and ulnar flexion), converted to angle measurement via the cosine value. The normal values are limited by the pathologic values, so that beginning lesions can be identified in this manner. Description of a few pathologic cases and of the limits and possibilities of the method.
