Dysbaric osteonecrosis: a reassessment and hypothesis.
Hutter CD.
Department of Anaesthesia, City Hospital, Nottingham, UK.
Dysbaric osteonecrosis is associated with exposure to large ambient pressure changes, and comprises necrotic lesions in the fatty marrow-containing shafts of the long bones, and the ball and socket joints (hips and shoulders). The fundamental causes are still in question and the illness remains a significant health hazard. Radiological and pathological features of both dysbaric and non-dysbaric osteonecrosis are indistinguishable and both are characterized by intramedullary venous stasis, ischemia and necrosis of bone. It has been generally accepted that gas bubbles (probably by initiating intramedullary venous stasis) are the prime cause of dysbaric osteonecrosis, as well as being responsible for Type 1 Decompression Sickness or 'the bends'. Importantly, however, not all series have found a correlation between dysbaric osteonecrosis and 'the bends'.
