Plasma mediated radiofrequency ablation (pmRFA) may allow for the percutaneous treatment of spinal tumors with a decreased risk of thermal injury to neural structures compared with traditional (radiofrequency or interstitial laser) ablation. However, usage of pmRFA has not been previously reported for a primary bone tumor, including an osteoid osteoma. Three patients with a spinal osteoid osteoma underwent pmRFA. The procedure was performed under computed tomography guidance using the 11 gauge Coblation SpineWand (ArthroCare). One lesion (at T11) was directly abutting the spinal canal. With an average follow-up of 20.7 (range 16-24) months, the mean Visual Analog Scale score for back pain decreased from 8.67 to 0.67 and no patient experienced tumor recurrence. pmRFA of spinal osteoid osteomas is feasible, even when the tumor is abutting the spinal canal. Larger studies with a longer follow-up are needed to further delineate the safety and efficacy of this technique.
等离子射频消融术（pmRFA）可能允许经皮治疗脊柱肿瘤，与传统的（射频或间质激光）消融相比，降低了对神经结构热损伤的风险。然而，pmRFA 以前并未用于原发性骨肿瘤，包括骨样骨瘤。3 名脊柱骨样骨瘤患者接受了 pmRFA 治疗。该手术在计算机断层扫描引导下使用 11 号auge Coblation SpineWand（ArthroCare）进行。一个病变（在 T11）直接紧贴椎管。平均随访 20.7 个月（范围 16-24 个月），背痛的平均视觉模拟评分从 8.67 降至 0.67，没有患者出现肿瘤复发。即使肿瘤紧贴椎管，pmRFA 治疗脊柱骨样骨瘤也是可行的。需要更大的、随访时间更长的研究来进一步明确该技术的安全性和有效性。
