Abstract:
[Objective]More accurate anatomical data is discussed to reveal the surrounding structures of the new and former BL54 (Zhibian, Chippen) according to the positional modification of acupuncture points by WHO (2006), and also to demonstrate the acupuncture stimulation points to the sciatic nerve as effective methods for acupuncture treatment of the pain in the lower back.
[Methods]Detailed dissections were performed on the surrounding structures of the acupuncture points of the bladder meridian at the gluteal region and the posterior aspect of the thigh in three cadavers at the Unit of Clinical Anatomy, Graduate School, Tokyo Medical and Dental University.
[Results] 1. The new BL54 (WHO, 2006) was situated at or near the infrapiriform foramen, with the posterior femoral cutaneous nerve, inferior gulteal nerve and vessels and sciatic nerve passing through.
2. The former BL54 was situated at or near the suprapiriform foramen with the inferior gulteal nerve and vessels passing through.
3. The acupuncture stimulation points to the sciatic nerve at the gluteal region and the posterior aspect of the thigh were as follows;(1) the initial portion of the sciatic nerve, (2) the infrapiriform foramen (new BL54, WHO), (3) the lateral one third point of the line connecting the sacrococcygeal junction and the greater trochanter, (4) the midpont of the line connecting the ischial tuberosity and the greater trochanter, (5) the point about 1 cm lateral to BL36 (Chengfu, Shofu), (6) the medial half portion of the biceps femoris muscle lateral to BL37 (Yinmen, Inmon).
[Conclusion] 1. The new and former BL54 are situated near the main nerves and vessels of the gluteal region and the posterior aspect of the thigh, so are considered as effective points for the acupunctural treatment.
2. The six positions are showed as the acupuncture stimulation points to the sciatic nerve in the gluteal region and the posterior aspect of the thigh.
