Long-term Side Effect of COVID-19 Infection; Osteonecrosis of the Femoral Head in SPECT/CT Bone Scintigraphy.

Avascular necrosis (AVN) of the femoral head is a condition characterized by limited mobility, discomfort, and changes in walking patterns due to insufficient blood supply in this region. Our objective is to investigate the possible connection between COVID-19 and AVN. In this study, we detail the case of a 41-year-old male patient who developed AVN in both femoral heads after contracting COVID-19. The mere occurrence of a COVID-19 infection and the use of corticosteroids for its treatment may increase the probability of AVN in the femoral head. Hence, post the COVID-19 pandemic, it is crucial to consider AVN vigilantly for timely detection and treatment.
