title: Kienböck's disease--update on silicone replacement arthroplasty.
abstract: In a previous paper, early lunate silicone replacement arthroplasty (SRA) for Kienböck's disease was advocated because of poor results obtained in stage III disease. Since then, an additional 16 patients have been operated on. Thirteen had stage III disease, and 12 underwent successful SRA. This result is attributed to the modification in anatomical configuration and the improvement in the physical characteristics of the new high-performance silicone lunate implant. Because SRA gives good results in a high percentage of patients in stage III disease, alternative modes of therapy may be considered in stage I or stage II disease without jeopardizing the ultimate result from SRA in stage III disease.
