[Replacement of the semilunar bone by the pisiform. Description of a new technique for the treatment of Kienboeck's disease].

Kienböck's disease treatment at stage III is difficult. We now present a new technic of replacement of the lunate by the pisiform with its vascular supply and attached to the flexor carpi ulnaris. Nine cases have been operated, on the first one in May 1979, with a follow up of 3 years. For the moment results are fair but we have to wait more to know if the technic is valuable.
