Kienbock's Disease

Plain films form the basis for staging and treatment of Kienböck disease. Lichtman's modification of Stahl's classification is most widely used and divides the disease into 5 stages, as follows:
Stage I - Normal radiograph
Stage II - Increased radiodensity of lunate with possible decrease of lunate height on radial side only
Stage IIIa - Lunate collapse, no scaphoid rotation
Stage IIIb - Lunate collapse, fixed scaphoid rotation
Stage IV - Degenerative changes around the lunate
