[Transposition of pedicled pisiform bone in the treatment of stage III lunate malacia].

In six patients who were suffering from Stage III Kienböck's disease, as defined by Decoulx, the lunate was completely removed and replaced by the pisiforme on its vascular pedicle. There was an average follow-up of twenty months. The authors report a reduction in the level of pain and a 40 degrees average increase in mobility.
