Five patients with Kienböck's disease had been treated by an osteotomy of the capitate (GRANER) with three poor results. In two cases necrosis of the capitate bone and resorption of the cancellous bone graft were obvious, perhaps due to damage of important vascular structures. Anatomical studies which have been carried out, showed that the main vessel of the capitate arises from the deep palmar arch and joints the bone on its ulnar-palmar and distal aspect. In order to achieve more satisfactory results with this operative procedure, the authors feel that it is important to protect the above mentioned vessel and indicate a more proximal osteotomy-site of the capitate bone.
