Concurrent Development of Septic Arthritis of the Acromioclavicular Joint and Osteomyelitis of the Acromion in a Pediatric Patient

The acromioclavicular joint is a rare location for the development of septic arthritis and osteomyelitis. If left untreated, these conditions are rapidly destructive and can cause significant morbidity. Individuals who are immunocompromised, use intravenous drugs, or have a history of shoulder trauma are at higher risk of developing septic arthritis. Having a high degree of suspicion is important in making a timely diagnosis and implementing appropriate therapy. We hereby describe a previously healthy 13-year old patient who presented with concurrent septic arthritis and osteomyelitis of the acromioclavicular joint.
