Area of Science:

  • Orthopedics
  • Infectious Diseases
  • Microbiology

Background:

  • Septic arthritis of the acromioclavicular joint (ACJ) is uncommon.
  • Septic arthritis of the ACJ caused by methicillin-resistant Staphylococcus aureus (MRSA) is exceptionally rare, with only two prior reports.

Observation:

  • A 46-year-old male presented with confirmed ACJ septic arthritis.
  • The causative agent was identified as MRSA.

Findings:

  • This case represents a rare instance of ACJ septic arthritis due to MRSA.
