Bacterial osteomyelitis in pediatric patients: a comprehensive review

Area of Science:

• Pediatric Infectious Diseases
• Musculoskeletal Imaging
• Pediatric Orthopedics

Background:

• Bacterial osteomyelitis is an infection of the bone, often challenging to diagnose in children because symptoms can be non-specific.
• The metaphysis is a common site for infection in immature bones, making understanding bone physiology key to understanding osteomyelitis.
• Accurate diagnosis and prompt treatment are vital to prevent long-term bone damage and complications.

Purpose of the Study:

• To highlight the diagnostic challenges of bacterial osteomyelitis in pediatric patients.
• To emphasize the importance of age-specific causative organisms and diagnostic imaging.
• To discuss the role of imaging and surgical intervention in managing pediatric osteomyelitis.

Main Methods:

• Review of the pathophysiology of osteomyelitis in skeletally immature patients.
• Analysis of common causative organisms based on patient age, including Staphylococcus Aureus and Kingella Kingae.
• Evaluation of the role of imaging modalities, particularly MRI, in diagnosis and management.
• Consideration of surgical intervention for diagnosis, treatment, and exclusion of mimics.

Main Results:

• Bacterial osteomyelitis diagnosis in children is complicated by nonspecific clinical presentations.
• Staphylococcus Aureus is the most frequent cause in pediatric pyogenic osteomyelitis.
• Kingella Kingae is prevalent in younger children (6 months to 4 years).
• MRI is the preferred imaging modality for suspected pediatric osteomyelitis.
• Imaging is essential for evaluating complications and differentiating osteomyelitis from other bone conditions.

Conclusions:

• Early and accurate diagnosis of pediatric bacterial osteomyelitis is critical.
• Identifying the specific causative organism, which varies by age, guides treatment.
• Advanced imaging like MRI and potential surgical intervention are key components of management.
