Abstract
Our Institutional Review Board approved this study Patients gave informed consent The inclusion criteria were a a painful spinal metastasis and b a distance of 1 cm or less between the metastasis and the spinal cord The thermocouple was placed in the spinal canal under CT fluoroscopic guidance When the spinal canal temperature reached 45°C RF application was immediately stopped RF ablation was considered technically successful when the procedure was performed without major complications Clinical success was defined as a fall in the visual analogue scale score of at least 2 pointsTen patients with spinal tumors measuring 3–8 cm mean 49 ± 15 cm were enrolled The distance between the tumor and the spinal cord was 1–6 mm mean 24 ± 16 mm All procedures were judged technically successful 100 The spinal canal temperature did not exceed 45°C in 9 of the 10 patients 90 In the remaining patient the temperature rose to 48°C resulting in transient neural damage although RF application was immediately stopped when the temperature reached 45°C Clinical success was achieved within 1 week in all patients 100
