Vascularized bone grafting for treatment of Kienböck's disease.

Treatment of Kienböck's disease has historically been determined by staging, ulnar variance, and presence or absence of arthritic changes. With the advent of newer techniques of vascularized bone grafting, the status of the cartilage shell of the lunate has become another factor that can influence the procedure performed. The purpose of this article is to describe the technique of the 4th plus 5th extensor compartment artery vascularized bone graft for Kienböck's disease.
