Reported here is the treatment of severe axial discogenic pain in a young man utilizing the new minimally invasive transdiscal radiofrequency technique called intradiscal biacuplasty (Baylis Medical Inc., Montreal, Canada). The new procedure is detailed and step-by-step fluoroscopic imaging presented. There were no intra- and postoperative complications, and significant improvements in patient functional capacity, and pain scores were noted. Visual analog scale pain score decreased from 5 to 1 cm at 6-month follow-up, Oswestry disability scores improved from 14 (28% or moderate disability) to 6 points (12% or minimal disability) and SF-36-PF (physical function) score changed from 67 to 82. Potential advantages of cooled, bipolar radiofrequency to heat the posterior annulus are discussed.
本文报道了一名年轻男性严重椎间盘源性轴向疼痛的治疗情况，采用了一种名为椎间盘内双极射频热凝术（加拿大蒙特利尔市贝利斯医疗公司）的新型微创经椎间盘射频技术。文中详细介绍了该新手术以及逐步骤的荧光透视成像。术中及术后均未出现并发症，患者的功能能力有显著改善，疼痛评分也有明显变化。在6个月的随访中，视觉模拟量表疼痛评分从5分降至1分，Oswestry功能障碍评分从14分（28%，中度功能障碍）改善至6分（12%，轻度功能障碍），SF-36身体功能（PF）评分从67分变为82分。文中还讨论了冷却双极射频用于加热后纵环的潜在优势。
