Implant-Associated Spinal Infections in Children: How Can We Improve Diagnosis and Management?

Area of Science:

• Orthopedic Surgery
• Pediatric Infectious Diseases
• Biomedical Engineering

Background:

• Implant-associated spinal infections complicate up to 10% of pediatric instrumented spinal fixation surgeries.
• These infections increase patient morbidity and healthcare system burden, particularly in children with neuromuscular scoliosis.
• Infections are categorized as early (≤90 days) or late, influenced by pathogen virulence.

Purpose of the Study:

• To review the incidence, risk factors, and management strategies for pediatric implant-associated spinal infections.
• To differentiate treatment approaches based on infection timing and causative pathogens.
• To explore potential advancements in managing these complex surgical site infections.

Main Methods:

• Literature review of pediatric spinal infection studies.
• Analysis of infection timing, pathogen characteristics, and treatment outcomes.
• Discussion of current and emerging therapeutic modalities.

Main Results:

• Early infections (e.g., Staphylococcus aureus) are often treated with debridement and implant retention.
• Late infections typically necessitate implant removal for effective treatment.
• Neuromuscular scoliosis patients face a heightened risk of developing these infections.

Conclusions:

• Effective management of pediatric spinal infections hinges on timely diagnosis and appropriate treatment selection.
• Further research into antibiofilm agents and advanced pathogen-specific imaging is warranted.
• Optimizing treatment strategies can mitigate patient morbidity and healthcare costs associated with spinal implants.
