Ischemic bone disease caused by decompression bubbles
Medical condition
Dysbaric osteonecrosis
Specialty
Diving medicine, occupational medicine
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 (N2) 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 hypotheses:
Intra- or extravascular nitrogen in bones, "nitrogen embolism".[citation needed]
Osmotic gas effects due to intramedullary pressure effects.[citation needed]
fat embolism[citation needed]
hemoconcentration and increased coagulability.[citation needed]
