Parvimonas micra Causing Emphysematous Osteomyelitis

A Case Report

Abstract

Case: 

We present an interesting case of femoral emphysematous osteomyelitis (EO) in a 67-year-old patient with the offending pathogen to be Parvimonas micra. Two knee arthrotomies with lateral thigh exploration were performed to debride and irrigate the bone and compartments. Although the patient initially improved, definitive treatment with an antibiotic intramedullary rod was necessary and resulted in complete resolution.

Conclusion: 

We present the first case of EO secondary to P. micra described in the literature and recommend aggressive surgical management for complete resolution and preserved functional outcome.
