Dysbaric Osteonecrosis

Excerpt

Dysbaric osteonecrosis is a type of avascular necrosis of the bone most commonly found in undersea divers and workers breathing compressed air or gas. This condition can lead to increased risk of fracture depending on the location and size of the bony defect. The rate of receiving total joint arthroplasty is increased in this patient population as well. The most commonly involved region is the hip joint, specifically the proximal femur, with bilateral involvement not being uncommon.
