目的设计一种新进路,使消炎镇痛液更集中地作用于病变神经根,或将胶原酶直接注射到突出的椎间盘而摆脱大型X线机的限制,更简便有效地治疗腰腿痛。方法通过解剖学研究、腰椎X线摄片,设计出经椎板外切迹进路到达硬膜外腔盘黄间隙并将其应用于临床。结果经椎板外切迹进路,可准确地到达硬膜外腔盘黄间隙,更有效地发挥治疗作用。结论该进路应用于溶盘术可免除大型X线机的限制,避免X线对医患双方的损伤。 Objective To design a new approach to anti-inflammatory analgesic more focused on the nerve root lesions or collagenase injection directly into the prominent disc and get rid of the limitations of large X-ray machine, more simple and effective treatment of low back pain. Methods Anatomical study and lumbar X-ray radiography were designed to reach the epidural space of the yellow disc through the extracardiac approach and apply it to clinic. The results of the translaminar approach, can accurately reach the epidural space disc yellow, more effective therapeutic effect. Conclusion This approach is applicable to plate-dissolving surgery to avoid the limitation of large-scale X-ray machines and to avoid the damage of both X-rays to both patients and patients.
