The clinical presentation and history of patients with Kienböck's disease do not permit differentiating avascular necrosis of the lunate from vague wrist pathology of a variety of causes. Diagnosis and evaluation of this disorder therefore require appropriate imaging studies. Plain-film radiography, tomography, and bone scintigraphy are useful screening tests, but MRI yields a definitive diagnosis. CT is also valuable for delineating structural changes and the amount of collapse in the lunate. The staging of Kienböck's disease is based on clinical and radiographic data.
