Successful treatment of late Salmonella infections in total hip replacement - report of two cases

Abstract

Background: Salmonella species can be rarely isolated from periprosthetic joint infections, however when present, are usually part of a severe septic clinical picture.

Case presentations: Two patients presented with late infected hip replacements to our institution. The first patient with multiple comorbidities had a confirmed Salmonella Enteridis infection with an abscess in the groin, with loosening of both components. He underwent a successful one stage cemented revision hip replacement, followed by 6 weeks of antibiotic therapy (ciprofloxacin). He had no recurrence or complications. The second patient was admitted in a septic condition with ARDS to the Intensive Care Unit 7 years following an uncemented total hip replacement. From an ultrasound guided hip aspirate Salmonella cholerae-suis was isolated. He underwent a successful a two-stage revision hip replacement.

Conclusions: Successful treatment of such potentially life threatening infections is achievable using modern orthopaedic techniques and close collaboration with the infectious diseases specialists.
