摘要
Abstract
Objective To explore the anatomical structure of the Erjian acupoint(LI 2).Methods ① Revi-ewing and summarizing the ancient literature regarding the location of the Erjian point.② Applying surface pressure on 30 volunteers to determine and mark the position where an"acupoint sensation"occurs.③ Conducting acupuncture at varying depths in the basal region of the proximal phalanx of the index finger,based on the marked locations,to determine the needle tip's position and depth when the"acupoint sensation"arises during acupuncture.Preliminary three-dimensional localization of the acupoint body was assessed by referencing sectional anatomical maps.④ Microscopic dissection on fresh upper limb specimens from ten individuals explored the anatomical entity at the identified Erjian locations using surface pressure and acupuncture.⑤Using ultrasonography to confirm the needle tip's position when an acupoint sensation arises during acupuncture at the Erjian point.⑥ Identifying the anatomical entity structure of the Erjian acupoint using an ultrasound imaging device,verifying the differentiation between its location and surrounding tissues under ultrasonographic guidance.Results ① According to the ancient texts,the Erjian acupoint is situated in the medial depression of the proximal phalanx of the index finger.② Acupoint sensations were elicited at the radial dorsal depression of the proximal phalanx of the index finger upon pressure.③ The most intense acupoint sensation occurred when needling the dorsal radial depression of the proximal phalanx of the index finger.④ Microscopic dissection revealed nutrient vessels entering the phalanx at the Erjian acupoint.⑤ When acupuncture was performed at the Erjian point,the needle tip was positioned at the dorsal radial bony hilum of the base of the proximal phalanx of the index finger.⑥ Ultrasonography confirmed the dorsal radial bony hilum of the base of the proximal phalanx of the index finger as the solid anatomical structure of the Erjian acupoint.Conclusion The solid anatomical structure of the Erjian acupoint is located at the radial dorsal bony hilum near the basal region of the proximal phalanx.The presence of the inherent dorsal branch of the volar artery indicates the entry of bone-nourishing blood vessels into the radial dorsal basal region of the proximal phalanx.关键词
