A toddler with transient synovitis and COVID‐19 infection

Transient synovitis of the hip is a common medical emergency in children. Although reactive arthritis in adults may occur 1-4 weeks after COVID-19 infection or post-vaccination, few reports of transient synovitis in children associated with acute COVID-19 infection have been made. Transient synovitis of the hip occurs most frequently in children 3-8 years of age with a recent upper respiratory infection, bacterial infection, or trauma. This case report presents a unique case of an otherwise healthy 15-month-old girl with right hip pain and the refusal to ambulate associated with COVID-19 infection.
