Spontaneous wrist fusion: An unusual complication of Kienböck's disease

We report a case of spontaneous wrist fusion occurring in a patient with magnetic resonance image (MRI)-proven stage 1 Kienböck's disease. The purpose of this case report is to make hand surgeons aware of this potential finding and to alert hand surgeons and radiologists that diffuse MRI changes of the lunate may not necessarily be pathognomonic for Kienböck's disease.
