Lunate sclerosis and collapse (flattening), compatible with advanced Kienböck disease.
Neutral ulnar variance.
Case Discussion
Kienböck disease refers to the avascular necrosis of the lunate bone, which is a rare condition with an unclear etiology.
Some conditions have been reported to be related to a greater risk of Kienböck's, such as systemic sclerosis and lupus.
Although negative ulnar variance is a known risk factor for Kienböck's it is not always observed, such as in the present case, which has a neutral ulnar variance.
