The lateral C1-2 puncture approach for myelography is a modification of the technique for percutaneous radiofrequency cervical cordotomy. Positioning of the needle in the posterior, rather than anterior, one third of the canal avoids injury to anomalous vertebral artery branches which lie in the anterior half of the neural canal at this level.
用于脊髓造影的C1-2外侧穿刺方法是经皮射频颈髓切断术技术的一种改良。将穿刺针置于椎管后三分之一而非前三分之一处，可避免损伤在此水平位于神经根管前半部分的异常椎动脉分支。
