Excision and fascial interposition arthroplasty in the treatment of Kienböck's disease.

Capitate shortening with capitate-hamate fusion is a joint leveling procedure designed for patients with Kienböck's disease who are in the early phases of this disease; that is, they have minimal or no fragmentation of the lunate, no arthritis, and no ulnar-minus variance. The long-term clinical results have been very good, and revascularization occurs in a high percentage of cases.
