title: [Long-term results of pisiform bone transposition in lunate necrosis].
abstract: Kienböcks disease is one of the most frequent manifestations of avascular necrosis. Multiple different surgical and conservative methods for treatment have been described. The transposition of pisiform on its vascular pedicle to replace the reamed out necrotic portion of the lunate has permitted revascularization and healing of the lunate. In the following article, the operative technique is described and the results of a five year follow-up study on 32 patients who underwent this operation are presented. On the basis of this study, we found, even in advanced cases of Kienböcks disease, that 50% of the 14 followed-up patients became free of symptoms or had pain only under stressful conditions.
