Abstract
Avascular necrosis (AVN) also referred to as osteonecrosis (ON) refers to inadequate perfusion to bone tissue resulting in death or necrosis of the bone. Although many known risk factors and etiologies exist, 20%-40% of AVN cases are idiopathic (1). There have been reported cases of osteonecrosis secondary to Covid-19 infection. However, these cases are typically attributed to the steroids used in the treatment plan of the viral infection. Here, we describe a case of idiopathic osteonecrosis attributed to a Covid-19 infection where the patient was not treated with steroids. We discuss a possible relationship between AVN and the cardiovascular system that may reflect an underlying cause contributing to avascular necrosis and Covid-19.
