Prosthetic device infections are caused by bacterial biofilms that resist antibiotics and host defenses. Early diagnosis and removal of infected prosthetics with antibiotic therapy are crucial for patient outcomes.

Area of Science:

  • Biomaterials Science
  • Microbiology
  • Infectious Diseases

Context:

  • Long-term prosthetic devices are susceptible to bacterial colonization.
  • Host proteins and bacterial extracellular polysaccharides form biofilms on prosthetic surfaces.
  • Biofilms impede host defenses and antibiotic efficacy, increasing infection risk.

Purpose:

  • To review the pathogenesis, clinical presentations, and management of prosthetic device infections.
  • To highlight the challenges posed by bacterial biofilms in prosthetic infections.
  • To emphasize the importance of accurate diagnosis and appropriate treatment strategies.

Summary:

  • Prosthetic devices are rapidly coated with host proteins, promoting bacterial adhesion and biofilm formation.
  • Bacterial biofilms decrease host defense mechanisms and antibiotic penetration, leading to increased infectivity.

  • Infections can occur perioperatively, via hematogenous seeding, or contiguous spread, presenting with diverse clinical signs.
  • Accurate diagnosis, often requiring invasive methods and microbiological analysis, is critical for effective treatment, typically involving prosthesis removal and antibiotic therapy.

    • Impact:

    • Understanding biofilm formation is key to preventing prosthetic infections.
    • Improved diagnostic methods can lead to earlier detection and intervention.
    • Effective management strategies are essential to mitigate the catastrophic consequences of prosthetic infections.
