Arthroscopic core decompression of the lunate in early stage Kienbock disease of the lunate.

Since the first description of Kienbock disease in 1910, the etiology and treatment have remained controversial topics. Core decompression is an accepted treatment option in early-stage avascular necrosis of the femoral head, and more recently the humeral head. This paper reports the technique of arthroscopic fluoroscopically guided core decompression of the lunate with 6-year results.
