Specifically, Kienböck's disease is another name for avascular necrosis [2] (death and fracture of bone tissue due to interruption of blood supply) with fragmentation and collapse of the lunate.

Dysbaric osteonecrosis or DON is a form of avascular necrosis where there is death of a portion of the bone that is thought to be caused by nitrogen (N 2) embolism (blockage of the blood vessels by a bubble of nitrogen coming out of solution) in divers. [1] Although the definitive pathologic process is poorly understood, there are several ...
