Management of Deep Spinal Wound Infections Following Instrumentation Surgery with Subfascial Negative Pressure Wound...

Area of Science:

• Spinal surgery outcomes
• Infectious disease management
• Wound healing technologies

Background:

• Deep wound infections post-spinal surgery present significant treatment challenges.
• Negative pressure wound therapy (NPWT) is an increasingly utilized and effective method for managing such infections.
• Understanding risk factors influencing NPWT efficacy is crucial for optimizing patient outcomes.

Purpose of the Study:

• To evaluate the effectiveness of NPWT in treating deep wound infections following spinal fusion.
• To analyze the impact of known patient-specific risk factors on the duration and success of NPWT therapy.
• To assess the association between risk factors and the number of NPWT revisions required for wound healing.

Main Methods:

• Retrospective analysis of 50 patients undergoing NPWT for deep wound infections after spinal fusion.
• Inclusion criteria: posterior and posteroanterior spinal fusion patients with deep wound infections.
• Data collected: patient demographics, risk factors (obesity, diabetes, etc.), infection characteristics, and number of NPWT revisions.

Main Results:

• Bacterial pathogens identified in 84% of cases, with *Staphylococcus epidermidis* and *S. aureus* being most common.
• An average of four NPWT revisions were needed for infection resolution; mixed pathogen infections required significantly more (5.3 vs. 3.3).
• No significant association was found between analyzed risk factors and the number of NPWT revisions.

Conclusions:

• NPWT is a highly effective treatment for deep wound infections after spinal fusion, ensuring infection cure and implant retention.
• The number of NPWT revisions in this study aligns with existing literature.
• Further research into specific risk factors is recommended to enhance prophylactic strategies and personalize treatment for postoperative wound healing disorders.
