decompression

The reduction of atmospheric pressure. Particularly, various techniques for preventing decompression sickness (also called caisson disease by gradual decompression. Decompression sickness is caused by the evolution of nitrogen bubbles in the body as a result of the effects of reduced atmospheric pressure. Normal symptoms of decompression sickness are the bends, chokes, and creeps; unconsciousness; and neurological symptoms. It can be potentially fatal if the original higher pressure is not restored. Fighter crews use pressure suits and pressure breathing to avoid the effects of decompression sickness. A sudden decrease in cabin pressure, which may be the result of either some component of the aircraft—such as doors, windows, or the cockpit canopy—giving way or a rupture taking place in the structure, is called explosive decompression. See also chokes and creeps.

The pathogenesis of avascular necrosis of femoral head (AVNFH) has not been fully understood.[sup][1],[2],[3] The AVNFH typically presents in the young adults and will quickly progress to femoral head collapse and arthritic changes in the absence of treatments.[sup][4] Therefore, hip joint preservation surgery should be considered to prevent the collapse of the femoral head or at least postpone the need for a hip arthroplasty.[sup][3],[5] The interventions include core decompression, osteotomies, and nonvascularized or vascularized bone grafting.[sup][6] However, osteotomies and bone grafting can cause severe trauma, which further undermines the femoral head blood supply system and worsens the ischemic conditions in the femoral head.
