Osteonecrosis 15 years after femoral neck fracture and long-term low-dose inhaled corticosteroid therapy

Posttraumatic avascular necrosis of the femoral head typically occurs immediately or within a few years after a femoral neck injury, and non-traumatic avascular necrosis is often related to systemic glucocorticoid therapy. We report an unusual case in which avascular necrosis of the femoral head occurred 15 years after a transcervical femoral fracture in a woman with a 20-year history of daily inhaled glucocorticoid therapy for chronic bronchitis. She had not taken glucocorticoids by any other route and had no other risk factors for osteonecrosis. To our knowledge, this is the first report of osteonecrosis associated with inhaled glucocorticoid therapy in a patient with a local cause of diminished vascular reserve. Inhaled glucocorticoid therapy should be added to the list of risk factors for osteonecrosis.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
