Right now, experts are continuing to look into the many implications COVID-19 could cause in the long term, including bone death.
However, the one apparent link which has emerged as the one probable causative factor is the overuse of steroids- which have been used as part of COVID care treatment and long debated.
Previously, the indiscriminate use of steroids in homecare/ hospitalized settings was also linked to the unproportional rise in black fungus cases amongst COVID-19 patients.
Medically, avascular necrosis is tied to a higher usage or dependence on high dose steroids, such as prednisone. While the exact cause is unknown, drugs like steroids, which are used to act down on inflammation caused by the virus can increase the level of lipid levels in the blood, which can reduce blood flow in the body, and cause damage to the vital tissues and organs.
Further evaluations and studies are needed to confirm the same. Yet, with the pace of the second wave slowing down, doctors now worry that the coming weeks will be a critical time since most cases of AVN start to show up months following steroid usage.
