Summary
Septic arthritis in children often presents with normal ultrasounds, necessitating prompt surgical intervention. Early synovectomy and drainage are crucial for good outcomes in pediatric septic arthritis.
Area of Science:
- Pediatric Orthopedics
- Pediatric Infectious Diseases
- Pediatric Radiology
Background:
- Septic arthritis is a serious joint infection in children.
- Early diagnosis and treatment are critical to prevent long-term joint damage.
Purpose of the Study:
- To evaluate clinical and microbiological features of septic arthritis in children.
- To determine the diagnostic sensitivity of ultrasound in pediatric septic arthritis.
Main Methods:
- Retrospective review of 36 children with septic arthritis of the hip.
- Analysis of clinical data, microbiological cultures, X-rays, and ultrasounds.
- Mean follow-up of 36 months.
Main Results:
- The hip was the most commonly affected joint (32/36 children).
- Microbiological diagnosis was achieved in 61% of cases, with Staphylococcus aureus being the most common pathogen.
- Ultrasound sensitivity was 64.5%, but lower in neonates. X-ray sensitivity was only 18%.
Conclusions:
- Ultrasound can be normal in pediatric septic arthritis, especially in neonates.
- Delayed surgical intervention is associated with poor outcomes.
- Immediate synovectomy and drainage are recommended upon clinical suspicion, even with a normal ultrasound.
