Septic arthritis of the acromioclavicular joint secondary to methicillin-resistant infection.

Septic arthritis of the acromioclavicular joint (ACJ) is a rare pathology with very few documented case reports available in the literature. In addition, ACJ septic arthritis secondary to methicillin-resistant (MRSA) is a rarer pathology with only two previously documented case reports in the medical literature to our knowledge. We present the case of a 46-year-old man who was diagnosed with a confirmed ACJ septic arthritis secondary to MRSA following admission to the local trauma and orthopaedic service at a district general hospital.
