Local Tumor Necrosis Factor Alpha Exposure Inhibits Posterolateral Fusion Rates in a Rat Model

Key Points

• To investigate how localized TNF-α exposure affects posterolateral fusion rates in a rat model after surgery.
• Administered localized TNF-α exposure post-surgery in rats
• Monitored fusion rates at the surgical site
• Compared outcomes with control group without TNF-α exposure
• Elevated TNF-α levels significantly impaired fusion rates
• Limiting TNF-α activity showed potential to improve arthrodesis outcomes
• Findings suggest a direct relationship between TNF-α and fusion effectiveness
