Summary
Treating biofilm infections in musculoskeletal conditions like chronic osteomyelitis requires both surgery and antibiotics. Biofilm-active antibiotics are crucial when implants are involved to ensure effective management of bone infections.
Area of Science:
- Orthopedics
- Infectious Diseases
- Microbiology
Background:
- Musculoskeletal infections often involve biofilms on non-living surfaces like dead bone or implants.
- Effective treatment necessitates a combination of surgical intervention and antimicrobial therapy.
Purpose of the Study:
- To review the management strategies for chronic osteomyelitis, periprosthetic joint infections, and implant-associated osteomyelitis of long bones.
- To highlight the importance of biofilm-active antibiotics in treating bone infections involving implants.
Main Methods:
- Literature review focusing on established treatment protocols for bone infections.
- Analysis of antimicrobial efficacy against bacterial biofilms relevant to orthopedic infections.
Main Results:
- Rifamycins demonstrate activity against staphylococcal biofilms.
- Fluoroquinolones are effective against Gram-negative bacilli biofilms.
- Combination therapy (surgery + antibiotics) is standard for curative treatment.
Conclusions:
- Management of chronic osteomyelitis and implant-associated bone infections requires a multimodal approach.
- Selection of biofilm-active antibiotics, such as rifamycins or fluoroquinolones, is critical when implants are present.
- Complete healing of infection is paramount before or during the implantation of new devices.
