Recent lessons for the management of bone and joint infections

Area of Science:

• Infectious Diseases
• Orthopedic Surgery
• Radiology

Background:

• Osteoarticular infections are evolving due to the rise of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA).
• CA-MRSA osteomyelitis presents with unique manifestations including multifocal disease, venous thrombosis, and pathologic fractures.
• Current treatment guidelines and diagnostic approaches require updates to address these changes.

Purpose of the Study:

• To review the changing epidemiology and clinical features of osteoarticular infections.
• To highlight the diagnostic role of MRI in musculoskeletal infections.
• To outline current and recommended therapeutic strategies for various causative pathogens, including CA-MRSA.

Main Methods:

• Literature review of recent studies on osteoarticular infections.
• Analysis of clinical manifestations and diagnostic imaging findings.
• Evaluation of antibiotic treatment protocols and surgical interventions.

Main Results:

• CA-MRSA is a significant driver of changing osteoarticular infection patterns.
• MRI is the preferred imaging modality for diagnosing musculoskeletal infections.
• Effective antibiotic choices include nafcillin/oxacillin or cefazolin for MSSA, beta-lactams for Kingella kingae, and vancomycin/clindamycin for CA-MRSA.
• Short courses of parenteral antibiotics followed by oral antibiotics are effective.
• Surgical drainage is frequently required for S. aureus infections.
• Collaboration with hematology is recommended for managing associated venous thromboses.

Conclusions:

• The emergence of CA-MRSA necessitates updated approaches to diagnosing and managing osteoarticular infections.
• Tailored antibiotic therapy and timely surgical intervention are crucial for favorable outcomes.
• Multidisciplinary collaboration improves patient care for complex cases.
