Pediatric Hematogenous Osteomyelitis: New Trends in Presentation, Diagnosis, and Treatment
Insights
Acute hematogenous osteomyelitis (AHO) in children presents more subtly now, requiring advanced imaging for diagnosis. Treatment trends focus on shorter antibiotic courses, but combined approaches are crucial for optimal outcomes.
Area of Science:
- Pediatrics
- Infectious Diseases
- Orthopedic Surgery
Background:
- Acute hematogenous osteomyelitis (AHO) in North American children has evolved significantly over recent decades.
- While classic presentations persist, subtle and subacute forms of AHO are increasingly common.
- Neonatal osteomyelitis incidence is rising due to intensive care unit procedures.
Purpose of the Study:
- To describe the changing characteristics of AHO in children.
- To highlight diagnostic challenges and advancements.
- To review current management strategies and trends.
Main Methods:
- Review of clinical presentations and diagnostic approaches for AHO.
- Analysis of the impact of advanced imaging technologies (bone scanning, MRI).
- Evaluation of treatment trends, including antibiotic duration and surgical intervention.
Main Results:
- AHO presentations are more varied, including subacute forms, Brodie's abscess, and epiphyseal osteomyelitis.
- Bone lesions can mimic neoplasms, often necessitating biopsy for diagnosis.
- Improved imaging aids in precise diagnosis and management.
- Shorter intravenous antibiotic courses may be appropriate under specific criteria.
Conclusions:
- The presentation of pediatric AHO has shifted, demanding broader diagnostic considerations.
- Advanced imaging plays a critical role in the diagnosis and management of AHO.
- Current treatment strategies balance efficacy with economic concerns, suggesting tailored antibiotic durations and combined therapeutic approaches.
Abstract:
The character of acute hematogenous osteomyelitis (AHO) in North American children has changed significantly during the past several decades. Although the typical clinical picture of established acute osteomyelitis in children (illness, dehydration, and an acutely painful limb) is still seen, more subtle presentations appear more frequently. Children often present with subacute osteomyelitis. Less common variants include Brodie's abscess, subacute epiphyseal osteomyelitis, and chronic recurrent multifocal osteomyelitis. Some patients present with a bone lesion that may be confused with other disease entities, including neoplasms. Biopsy is often needed to clarify the diagnosis. With the trend toward more invasive procedures in the neonatal intensive care unit, neonatal osteomyelitis is also seen more frequently. Advances in imaging technology, particularly improvements in technetium bone scanning and the advent of magnetic resonance imaging, have contributed to more precise diagnosis and better management of AHO. With the increased concern about medical economics, the recent trend toward decreasing the duration of intravenous antibiotic treatment of these infections appears to be appropriate as long as certain criteria are met. Neither surgery nor antibiotics alone will be associated with successful treatment in all cases, and this fact may explain the rare but continued morbidity that is still seen in children with AHO.
