Objective: To search for the best functional locations of Hua Tuo Jia Ji points so as to approve the clinical therapeutic effect. To observe the therapeutic effect of Prolapse of lumbar intervertebral disc treated with those points.

Methods: (1) Locating method: The needle was inserted 2.5cm lateral to the posterior middle line, between the lumbar spinal processes. Jiaji (EXB2) Points were frequently selected from L4-L5, L5-S1 and L3-L4 (since the attack rates on those regions were 70%, 20% and 10% successively). In consideration of the involvement of the spinal nerve root of sciatic, Jiaji points on the affected side were firstly selected in the treatment and the points were, selected bilaterally or contralaterally according to the case; (2) Manipulation: The patient was in a prone position and a pillow was put under the abdomen. The lumbar region was completely exposed. Every process during the treatment was in a strict sterilized condition. The thumb and index finger of the left hand stabilized the point. The puncture needle was inserted quickly on the selected lumbar Jiaji point (EX-B2), then to the spinal column at an angle of 45° formed by the needle body and the body sagittal plane. The resistance was felt when the needle tip touched the yellow ligament and a hollow sensation were obtained When more strength was given (at such moment the tip was touched the extradural interspace). When the hollow sensation appeared, the needle should stop going immediately and the needle body was withdrawn 1 mm and the tip was kept on the most lateral side of the extradural interspace to prevent from injury of spinal nerve and blood vessels or dura mater of spinal cord and misentering subarachnoid cavity. The negative electrode of the electric anesthesia apparatus was attached on the handle and the positive end on the skin with a piece of wet alcohol cotton, 3cm far from the inserting area. The electric intensity and frequency were adjusted in a proper position and the needling sensation was observed. If the location was correct, the sensation should be conducted to the sore and toes of the affected side. The needle was retained for 1 to 3 minutes (electric needling therapy). After that, 2 ml air was injected through the puncture needle by the 5ml syringe. The location was correct if there was no resistance and no flowing of blood and cerebrospinal fluid; then the prepared medicine liquid was injected. After injection, the puncture needle was withdrawn to the lateral side of the yellow ligament and the surgical catgut was put in the puncture needle carefully and was put to the deep region by the stylet. At the end, the puncture needle and stylet were removed, the puncturing area was pressed with a piece of dry alcohol cotton and fixed with plaster. The patient was advised to rest on the bed for half an hour.

Results: Of 360 cases, after 1 to 4 treatments, 160 cases were cured (the clinical symptoms disappearance, free movement of the lumbar and legs, normal physical work and no reoccurrence in one year), 180 cases improved (the clinical symptoms were obviously relieved, Pain and discomfort happened after strain and long time walking and the symptoms were relieved after rest), 20 cases no effect (no significant difference of the Symptoms and physical signs before and after treatment). The effective rate was 94.4%.

Conclusion: The therapeutic effect was significant for treatment of prolapse of lumbar intervertebral disc with the comprehensive theory on Hua Tuo Jia Ji points.
