Background

  • Also known as postoperative spinal implant infection

Classification

Classification Acute Infection Chronic Infection
Pathogenesis: post-interventional <6 weeks post-interventionally (early onset) ≥6 weeks post-interventionally (late onset)
Pathogenesis: hematogenous or per continuitatem <6 weeks of symptoms ≥6 weeks of symptoms
Clinical presentation acute pain, fever, prolonged wound secretion (>7-10 days), acute neurological deficits chronic pain, implant migration or loosening, fistula, neurological deficits
Typical pathogens Staphylococcus aureus, Streptococcus, Gram-negative bacteria coagulase-negative staphylococci, Cutibacterium acnes

Management

  • Empiric therapy should be with vancomycin plus ceftriaxone or vancomycin plus piperacillin-tazobactam
  • Antimicrobial management depends on the surgical approach:
    • For removal of all hardware, treat with 6 weeks total (at least 2 weeks IV)
    • For retainment with plan for eradication, treat with 12 weeks total (at least 2 weeks IV)
    • For single-stage replacement, treat with 12 weeks total (at least 2 weeks IV)
    • For retainment with plan for eventual removal, treat with at least 2 weeks IV followed by oral suppression until hardware removal
  • Chronic suppressive antibiotics should be considered with difficult-to-treat organisms (Staphylococcus aureus, resistant Gram-negative bacteria, and fungal infections)
