The anatomical structures vulnerable to acupuncture around the PC6 acupuncture point were investigated. Needles were inserted in PC6 of eight wrists from four cadavers to a depth of 2 cm, the forearms were dissected and the adjacent structures around the path of the needles were observed. The needles passed between the tendons of the palmaris longus and flexor carpi radialis muscles and then penetrated the flexor digitorum superficialis, flexor digitorum profundus and pronator quadratus muscles. The inserted needles were located adjacent to the median nerve. To minimise the risk of unintended injury by acupuncture, it is recommended that needles should not be inserted deeply at the PC6 acupuncture point. An understanding of the anatomical variations of the median nerve and the persistent median artery in the forearm is of clinical importance when performing acupuncture procedures.
研究了 PC6 穴位周围易受针刺影响的解剖结构。从四具尸体的八只手腕上插入 PC6 穴位的针深 2 厘米，解剖前臂，观察针道附近的相邻结构。针穿过掌长肌腱和桡侧腕屈肌肌腱之间，然后穿透指浅屈肌、指深屈肌和旋前方肌。插入的针位于正中神经附近。为了最大程度地降低针刺意外损伤的风险，建议在 PC6 穴位不要深刺。了解前臂正中神经和固有正中动脉的解剖变异，在进行针刺操作时具有重要的临床意义。
