[Graner's intercarpal arthrodesis as therapy of aseptic lunate bone necrosis]

From 1978 till 1989 at the Department of Orthopaedics (University of Graz, Faculty of Medicine, Division of Surgery) 25 patients were operated for the reason of an avascular necrosis of the lunate bone when the bone structures were already destroyed. The form of therapy was the intercarpal-arthrodesis, developed by Orlando Graner 1966, in a slightly modified way. On the one hand through creating an intercarpal block it is possible to create more or less plain sides of the radiocarpal joint and on the other hand one can stop the carpal collapse what explains long-term-results rather acceptable. The most important disadvantage of this form of therapy is the often found loss of range of movement in the operated radiocarpal joint.
