What is Acute Osteomyelitis in Children?

Pediatric osteomyelitis usually occurs through hematogenous spread to richly vascularized metaphyses, especially of the femur, tibia, and humerus.

Staphylococcus aureus (including MRSA in many regions) is the predominant pathogen; Kingella kingae is increasingly recognized in children under 4.

Diagnosis combines clinical presentation, elevated CRP/ESR, blood and bone cultures, MRI (gold standard), and ultrasound for joint effusion.

Without prompt treatment, infection can spread to adjacent joint causing septic arthritis, or progress to chronic osteomyelitis with sequestrum formation.

Symptoms

Localized bone pain with refusal to bear weight or limp
Fever, malaise, and irritability in younger children
Swelling, warmth, and tenderness over the affected metaphysis
Decreased range of motion in the adjacent joint
Pseudoparalysis of the limb in infants
Recent skin infection, trauma, or upper respiratory infection in the history

Risk Factors

Recent minor trauma to the affected area
Skin and soft tissue infections (impetigo, furuncle)
Sickle cell disease (Salmonella osteomyelitis risk)
Indwelling vascular catheters or recent hospitalization
Immunocompromise from chemotherapy or congenital immunodeficiency
Age under 5 years (peak incidence)

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Persistent limb pain with limp or refusal to bear weight
  • Fever and bone pain in a child
  • Localized swelling with warmth over a long bone
  • Worsening pain after recent injury
  • Joint swelling with bone tenderness suggesting septic arthritis
  • Failure to improve despite oral antibiotics for skin infection

Treatment Methods

01
Empiric IV antibiotics covering MSSA and MRSA (cefazolin, clindamycin, or vancomycin per local resistance)
02
Modify therapy based on culture and susceptibility results
03
Total duration typically 3-6 weeks, with early oral switch (after 5-7 days IV) when clinical and CRP response is good
04
Surgical drainage for abscesses, sequestra, or failed medical therapy
05
Joint aspiration and washout if septic arthritis is present
06
Outpatient parenteral antibiotic therapy or oral step-down with close monitoring
