Osteonecrosis - Prevention

Alternative Names

Avascular necrosis; Osteonecrosis; Ischemic bone necrosis; AVN; Aseptic necrosis

Prevention:

Many cases of osteonecrosis do not have a known cause, so prevention may not be possible. However, in some cases, you can reduce your risk by doing the following:

  • Avoid drinking excessive amounts of alcohol.
  • When possible, avoid high doses and long-term use of corticosteroids.
  • Dive safely to avoid decompression sickness.
