title: Kienböck's disease.
abstract: Kienböck's disease is a progressive disruption of the lunate secondary to avascular necrosis, which may be due to the lunate's precarious blood supply, external compression forces, and fractures of its surfaces. The treatment options for Kienböck's disease are based on the stage of the disease, defined by Stahl, and include immobilization, radial shortening or ulnar lengthening, intracarpal fusion, and prosthetic replacement. The prognosis for functional recovery is better in stage I and II disease, which emphasizes the need for early diagnosis.
