# Isolated Acromioclavicular Joint Septic Arthritis: A Case Report and Review of Literature

## TL;DR

A 60-year-old diabetic patient was diagnosed with septic arthritis in the acromioclavicular joint and successfully treated with surgery and antibiotics.

## Contribution

This paper presents a rare case of isolated acromioclavicular joint septic arthritis and reviews existing literature on the condition.

## Key findings

- The patient had pus and bony erosion in the acromioclavicular joint caused by MRSA.
- Treatment involved surgery, debridement, and targeted antibiotic therapy.
- Prompt diagnosis and treatment are crucial to reducing complications from septic arthritis.

## Abstract

A 60-year-old diabetic patient presented with acute pain and swelling localized to the left acromioclavicular joint. Laboratory and radiological investigations revealed the presence of pus in the left acromioclavicular joint along with bony erosion of the lateral end of the left clavicle. She was treated with open arthrotomy, debridement, and appropriate antibiotics for the causative methicillin-resistant Staphylococcus aureus (MRSA) infection. Prompt diagnosis and timely intervention can reduce the morbidity and mortality due to septic arthritis. We conducted a review of the literature on patients treated for isolated septic arthritis of the acromioclavicular joint.
