Percutaneous Radiofrequency Ablation of Spinal Osteoid Osteomas Using a Targeted Navigational Bipolar Electrode...

Area of Science:

• Minimally Invasive Orthopedic Surgery
• Interventional Radiology
• Oncology

Background:

• Spinal osteoid osteomas are benign bone tumors causing pain.
• Traditional treatments can be invasive with potential complications.
• Percutaneous radiofrequency ablation (RFA) is an established treatment option.

Purpose of the Study:

• To evaluate the safety and efficacy of a novel targeted navigational bipolar electrode system for CT-guided RFA of spinal osteoid osteomas.
• To assess the system's ability to achieve optimal nidus access, particularly in difficult anatomical locations.
• To determine the system's effectiveness in real-time monitoring and minimizing thermal injury.

Main Methods:

• Percutaneous CT-guided radiofrequency ablation procedures were performed.
• A targeted navigational bipolar electrode system with articulating electrodes and built-in thermocouples was utilized.
• Variable generator wattage settings were employed.
• Ablation zone volume and geometry were monitored in real-time.

Main Results:

• The procedure demonstrated safety and effectiveness in treating spinal osteoid osteomas.
• The articulating bipolar electrodes facilitated optimal nidus access, even in challenging spinal locations.
• Precise real-time monitoring of ablation parameters was achieved.
• The risk of unintended thermal injury to surrounding tissues was minimized.

Conclusions:

• The targeted navigational bipolar electrode system is a safe and effective tool for percutaneous CT-guided radiofrequency ablation of spinal osteoid osteomas.
• This technology enhances precision, improves access in difficult cases, and offers superior safety by minimizing thermal damage.
