Irregularity, collapse, and sclerosis of the lunate bone indicate Kienbock disease. There is substantial ulnar negative disagreement.
Case Discussion
Imaging features of Kienbock disease on plain film include sclerosis and flattening of the lunate. When flattening is marked there is rotation of the scaphoid which further adds to the stress on the lunate. Fragmentation of the lunate and secondary degenerative disease develops.
