Orthopedic implant-associated infection: the main etiological agents, local resistance and antimicrobial therapy recommendations

Abstract

Surgical site infections remain a major complication of arthroplasty, spinal stabilization or other orthopedic surgeries. The pathogenesis of these complications is related to use orthopedic implants. This retrospective study investigated the microbiological etiology of implant-associated infection after orthopedic surgery over a 3-year period (2010-2012). The antibiotic resistance profiles of 1350 clinical microbial isolates were determined. The biofilm forming capacity of 394 staphylococcal strains was tested. Statistical analysis was performed using Z-criterion. From a results of the microbiological culture, Staphylococcus aureus and Staphylococcus epidermidis were isolated in 49,9% of cases, followed by: Enterococcus faecalis - 6,4%, Pseudomonas aeruginosa - 5,9%, Acinetobacter spp - 5,1% and members of the family Enterobacteriaceae - 4.1%. MRSA amounted to 23,9% and MRSE - 56,6% (p
