Arterial Constriction

The acupuncture point “Hegu” (LI4) has been used for treating peripheral circulatory failure, which is located in the area covered by the superficial branch of the radial nerve (SBRN). SBRN has branches reaching arteries, so-called vascular branches (VBs), which are thought to be involved in the arterial constriction. The distribution areas of the VBs from the SBRN have been reported, but the positional relationship between these distribution areas and the acupuncture points are not known. To examine the positional relationship between LI4 and VBs from the SBRN, forty hands were examined to assess the positional relationship between the acupuncture points “Erjian” (LI2), “Sanjian” (LI3), LI4, and “Yangxi” (LI5) in the Yangming Large Intestine Meridian of Hand, which are located in the area covered by SBRN, and the VBs from the SBRN. After the VBs were identified, the distances from the acupuncture points (LI2, LI3, LI4, and LI5) to the point where the VBs reached the radial artery or the first dorsal metacarpal artery were measured. VBs reaching the radial arteries were observed in all specimens. The mean distances from LI2, LI3, LI4, and LI5 to the point where the VBs reached the radial artery were 64.2 ± 8.2 mm, 42.0 ± 7.5 mm, 4.3 ± 4.3 mm, and 33.0 ± 4.8 mm, respectively. LI4 was significantly closer than the other acupuncture points (P<0.01). The nerve fibers of the VBs adjacent to the radial artery were confirmed using hematoxylin and eosin staining. Our findings provide anatomical evidence that stimulation at LI4 is used for treating peripheral circulatory failure such as Raynaud’s disease. LI4 is significant because it is located at a source point, making it clinically important.

AbstractThis study assesses the usefulness and feasibility of an osteosynthesis of the lower end of the radius under ultrasound imaging to avoid the superficial branch of the radial nerve (SBRN). A single operator performed an initial echography of the wrist of 12 cadaveric upper limbs to identify the three main branches of the SBRN and the tendons. Then, three pins were placed according to Kapandji's procedure, avoiding the structures spotted under ultrasound imaging. After dissection, the safety distances for the branches of the SBRN, dorsal extensor tendons, and veins were measured, and injuries to these structures were noted. No lesion of the SBRN was found with an average safety distance of 8.1 for the third branch of the radial nerve (SR3) and 1.3 mm for the first and the second branches of the radial nerve (SR1–2). Three tendons were spiked. The average operative time was 38.3 minutes. Ultrasound secures percutaneous surgery to avoid the branches of the SBRN but requires a learning curve.

Wartenberg’S Syndrome

We dissected 20 preserved Caucasian cadaveric upper limbs looking at the relation of the superficial branch of the radial nerve (SBRN) to the brachioradialis tendon. SBRN emerged from deep to superficial position by piercing the brachioradialis tendon near its dorsal border in four limbs. The resulting dorsal tendinous band compressed the nerve and prevented longitudinal gliding movement during ulnar flexion. This is likely to increase the risk of chronic compression neuropathy (Wartenberg's syndrome). In two of these four limbs, there was a communication between the SBRN and lateral cutaneous nerve of the forearm. No such communication was found in the remaining 16 forearms. This communication could contribute to the minimal area of sensory loss observed in Wartenberg's syndrome. We recommend that this anatomical anomaly is looked for and if present dealt with during surgical treatment of Wartenberg's syndrome, as it is likely to predispose to chronic compression neuropathy.
