Who is the convict; COVID-19 or corticosteroid? Late onset avascular necrosis of hips after COVID-19. A case report with literature review.

AIM: Avascular necrosis (AVN) or osteonecrosis is characterized by death of bone tissue due to endothelial damage and vascular abnormality. Coronavirus can induce endothelial damage and abnormal blood clotting, so that COVID-19 is known as a vascular disease. We aim to evaluate the relationship between AVN and COVID-19.

CASE: Here we present a 39-year old man with severe COVID-19 and corticosteroid consumption who developed late onset AVN of both hips 20 month after COVID-19.

CONCLUSION

An awareness of the possible osteonecrosis for all physicians dealing with patients with musculoskeletal problems following COVID-19 is necessary.
