Comprehensive treatment algorithm of postoperative spinal implant infection

Area of Science:

• Spinal Surgery
• Infectious Diseases
• Orthopedics

Background:

• Postoperative spinal implant infection (PSII) is a significant complication following instrumented spinal surgery.
• Early-onset PSII is typically diagnosed via clinical symptoms.
• Late-onset PSII diagnosis often relies on intraoperative sample analysis.

Purpose of the Study:

• To outline diagnostic and treatment strategies for postoperative spinal implant infections.
• To differentiate management approaches for early-onset versus late-onset PSII.
• To detail antibiotic therapy recommendations based on implant status and pathogen sensitivity.

Main Methods:

• Review of diagnostic criteria for early and late-onset PSII.
• Analysis of surgical treatment options including implant retention, removal, or exchange.
• Evaluation of antibiotic therapy protocols, considering pathogen sensitivity and biofilm activity.

Main Results:

• Early PSII may be managed with implant retention, while late PSII typically necessitates one-staged implant exchange.
• Radical debridement of surrounding tissue is essential for all PSII cases.
• Antibiotic treatment duration varies: 12 weeks with implant retention for sensitive pathogens, prolonged for problematic ones, always initiating with intravenous therapy for at least two weeks.

Conclusions:

• Effective management of PSII requires a tailored approach based on infection onset, pathogen characteristics, and implant status.
• Surgical intervention, including debridement and appropriate implant management, is a cornerstone of PSII treatment.
• Optimized antibiotic regimens, initiated intravenously, are critical for successful PSII eradication.
