Diagnosis and management of acute osteoarticular infections in children

Area of Science:

• Pediatrics
• Infectious Diseases
• Orthopedic Surgery

Background:

• Acute hematogenous osteomyelitis and septic arthritis are common pediatric infections.
• Limb pain and pseudoparalysis in children necessitate considering these conditions.
• Bacterial seeding to bone is the primary cause of pediatric bone infections.

Purpose of the Study:

• To outline the diagnosis and management of pediatric osteomyelitis and septic arthritis.
• To review common pathogens and optimal empiric and definitive antimicrobial therapy.
• To update recommendations on the duration of antimicrobial treatment for osteomyelitis.

Main Methods:

• Review of current literature and clinical guidelines.
• Identification of common bacterial pathogens, including Staphylococcus aureus and Kingella kingae.
• Discussion of diagnostic evaluation, including orthopedic consultation and aspiration.

Main Results:

• Prompt orthopedic evaluation is crucial for septic arthritis, including aspiration and potential debridement for concurrent osteomyelitis.
• Intravenous cefazolin is the recommended empiric therapy post-culture.
• Conversion to oral antimicrobials is indicated upon clinical improvement and decreasing inflammatory markers.

Conclusions:

• Pediatric osteomyelitis and septic arthritis require timely diagnosis and management.
• Antimicrobial therapy duration for uncomplicated osteomyelitis is now recommended at 3-4 weeks.
• Early intervention and appropriate antibiotic selection are key to favorable outcomes.
