[Show abstract][Hide abstract] ABSTRACT: OBJECTIVE: We present three cases of symptomatic high-risk metastases involving the vertebral body treated using infused bipolar radiofrequency ablation either alone or in combination with vertebroplasty. CONCLUSION: In our experience, the bipolar technique can reduce the risk of spinal cord damage in radiofrequency ablation of lesions within 1 cm of neural structures and involving paravertebral soft tissue.

[Show abstract][Hide abstract] ABSTRACT: Radiofrequency current and laser energy can be delivered locally through electrode-needle or optical fiber inserted in the tissue and allows local ablation of tissues, up to a volume of 4 to 5 cm in diameter with one application or vaporizes tissue. Tumor ablation guided with medical imaging proved a high local efficacy over 90% for tumors less than 25 mm in the liver, lung, and kidney. The spinal applications of the thermal energy of RF and laser are reported in this paper. First, the tumor ablation is reviewed with malignant and benign tumors. In malignant tumors, radiofrequency is very efficient in local tumor control and in pain management. The second part of this paper is devoted to disk diseases where laser and RF techniques increase their applications. The technique, indications and results of these techniques are reported and illustrated.
