A Case Report

Abstract

Case: 

A 72-year-old woman with a history of right total hip arthroplasty and subsequent revision 18 years ago developed right hip periprosthetic joint infection with significant bone destruction caused by Slackia exigua. She underwent a dental cavity filling without prophylactic antibiotics before presentation that may have contributed to development of the infection. The patient required total hip revision and prolonged antibiotic therapy to eradicate the bacteria.

Conclusion: 

This case is an example that certain high-risk patients undergoing invasive dental procedures are at risk of developing prosthetic joint infection.
