他想到PCD这种新技术，在原文中是这样描述的:“During a vertebroplasty procedure， the authors observed that the adjacent disc with vacuum phenomenon filled with PMMA， and signs of instability had disappeared on postoperative X-ray. This led to the development of the PCD procedure: PMMA augmentation of the intervertebral disc with vacuum phenomenon in patients otherwise not suitable for more invasive surgery. The hypothesis of the authors is that， by filling disc space with PMMA， instability is decreased， thus reducing in turn pain and disability”.
在骨科门诊中，腰痛是常见的主诉。据估计，在所有人群中，一生中的某个时段发生过腰痛的比率为80%。在任何时候，大约18%的人群正在经历腰痛。一般急性腰痛经过休息、理疗、药物等对症治疗可明显好转，常规不需拍摄腰椎影像学检查 (但超过2周持续腰痛或反复发作，则需进一步检查)。

随着脊柱内镜技术与理念的不断进步，适应证不断得到突破，从早期的单纯椎间盘突出症，到各种复杂类型的椎间盘突出症、腰椎管狭窄症、腰椎滑脱症，再到神经根型颈椎病、合并后方压迫的短节段甚至长节段脊髓型颈椎病、胸椎管狭窄症等，均可借助内镜技术获得满意的临床疗效，并发症更低、术后康复快。
