Mycobacterium chelonae is a rare, atypical nontuberculous bacterium that has been reported to be an underlying cause of persistent wound infections. Although there are several studies highlighting the role of M chelonae as the putative cause of other postoperative wound infections, to our knowledge there ar e no reports of infection following implant placement for repair of an orbital floor fracture. The authors present a unique case describing the management of a persistent postoperative infection in a young, immunocompetent patient with an orbital floor fracture repaired with a Stryker Medpor Titan implant. The patient was initially treated with broad-spectrum antibiotics with minimal clinical improvement. Following culture-proven M chelonae, a second surgical intervention was undertaken to remove the implant and later, a third intervention for scar revision. The patient has remained free of infection utilizing a long-term tailored 2-drug antibiotic regimen. This case emphasizes the need for recognition of M chelonae as a potential pathogen in certain clinical situations and the difficulty in eradicating M chelonae in the context of infected implantable devices. The comprehensive treatment protocol required to ensure adequate therapy is reviewed. Address correspondence and reprint requests to J.
