Kienbock Disease

• Avascular necrosis of the lunate

• Associated with negative ulnar variance (ulna is shorter than the radius)

• XR = sclerosis and flattening of lunate

• MRI = best test

  • Sclerosis centrally (low T1 & T2)

  • May see edema in acute phase

• Conservative management, surgery only if all else fails
