[Anatomical investigation of the blood-supply of the lunate bone (author's transl)].
The lunate bone receives its blood-supply via a palmar and a dorsal vascular and fibrous strand. When the wrist is extended the dorsal vessels are caught in a kind of vice formed by the radius and the capitate bone and compressed up to complete occlusion. This mechanism, important for the pathogenesis of Kienböck's disease, is demonstrated on anatomical specimens.
