Mycobacterium abscessus Periprosthetic Hip Infection Complicated by Superimposed Polymicrobial Infection: A Case Report.

CASE: A 79-year-old man developed Mycobacterium abscessus prosthetic joint infection (PJI) after hip hemiarthroplasty that was complicated by polymicrobial infection. He was ultimately treated with resection arthroplasty and chronic suppressive therapy. He has had no evidence of recurrent infection after 2 years of follow-up.

CONCLUSION

As far as we know, this is the first reported case of M. abscessus hip PJI complicated by superimposed polymicrobial infection. This case demonstrates the challenge of treating M. abscessus infection, the need for a multidisciplinary approach with aggressive surgical intervention, and prolonged combination antimicrobial therapy for a successful outcome.
