Through the study of a large number of cases of lumbar synostosis, it was found that in the early stage of the disease, wind, cold, dampness, qi stagnation and blood stasis were the main causes of the disease; in the middle stage, the evil caused injury to the positive, resulting in different degrees of deficiency of qi, blood, yin and yang; in the late stage, the evil was gradually removed, but the positive was not restored. On this basis, six major Tui Na treatments have been established: (1) emphasize the whole body, treat the upper disease downward, and treat the left and right together; (2) treat the disease by the tendons and the disease by the pain; (3) treat the disease by the qi and blood, and treat the disease in different ways; (4) treat the disease by the urgency and slow it down; (5) treat the disease by combining it and treating it by dividing it; (6) make it appropriate according to the person, the time, the disease, and the location. In clinical practice, we apply the theoretical knowledge of physiology, pathology, anatomy and biomechanics of modern medicine, and combine the identification of evidence with the identification of disease. We analyze wind, cold, dampness, phlegm, stasis, kidney deficiency and blood deficiency in Chinese medicine, and often identify bone injuries from wind, cold and dampness, stagnation of qi and blood, phlegm and stagnation of ligaments, deficiency of liver and kidney, and deficiency of qi and blood; at the same time, we also fully recognize the objective existence of pathological changes such as aseptic inflammation, edema, adhesions and nerve root stimulation and compression caused by soft tissue injury, fibrosis, osteophytes and disc herniation in Western medicine. We have established the treatment principle of relieving tendons and channels, activating blood circulation and relieving pain, and loosening adhesions, which has achieved good clinical results. 2. Clinical experience of central lumbar synostosis treated with Tui Na Modern medicine always considers central lumbar synostosis as a forbidden area for Tui Na treatment. We understand and analyze the etiology and pathology of this disease from both Chinese and Western medicine, break through the tradition, give full play to the effect of Tui Na in Chinese medicine of dispelling wind and cold, resolving phlegm and dampness, promoting qi and blood, and nourishing liver and kidney, and apply the three principles and six treatments of Tui Na therapy to treat central lumbar protrusion with the gentle and deep penetrating four-finger Tui Na technique. We have treated a large number of patients diagnosed with central lumbar synostosis by CT or MRI examination and achieved satisfactory results. Central lumbar protrusion should have the corresponding medical history, symptoms and signs. However, it is possible to release the adhesions and change the pressure on the nerve roots, i.e., in terms of traditional Chinese medicine, “the passage is not painful”. There have been reports of paraplegia caused by the rupture of the annulus fibrosus and the protrusion of large pieces of the nucleus pulposus into the spinal canal due to excessive or violent massage techniques. In our clinical practice, we have followed the ancient motto of “touching the machine on the outside, being skillful on the inside, the method coming from the hand, the hand following the heart”, and “making the patient unaware of the suffering” to completely avoid the above problems, and there has not been a single case of adverse accident. We believe and clearly propose to our domestic counterparts that central intervertebral disc herniation is really difficult to treat, but it is not a forbidden area if the Tui Na technique is properly applied. In treatment, it is necessary to understand the disease from the mechanism of modern medicine – to confirm that there is something protruding to the center, so it is necessary to be cautious; also from the overall concept of Chinese medicine to combine dialectical evidence and disease, according to its cause, symptoms and different parts, dialectical treatment, manipulation should be gentle, especially in the acute attack, if necessary, can avoid the lesion parts, can In the recovery phase or chronic phase, the technique can be taken appropriately, but to the extent that the patient can tolerate it. For central lumbar protrusion, “pain” is the main pain. According to the principle of “the tendons are the disease, pain is the yu”, the point is pressed from light to heavy at the A-Yi point, avoiding roughness, or using a mango needle. The treatment starts with activating blood stasis, promoting paralysis and clearing the ligaments, and tonifying the liver and kidneys. The relationship between “loose”, “smooth” and “moving”, especially “loose” as the first, loose is smooth, smooth is moving, moving is through. 3, the posterior traction and extraction method under confrontation traction is the key technique for treating lumbar prolapse. The posterior traction and extraction method under confrontation traction is a compound technique of confrontation traction, posterior traction, extraction and extension. This is the key technique for the treatment of lumbar synostosis, which is to change the position of the nerve roots and other tissues to reduce or eliminate the pressure on the nerve roots. Operation method: The patient holds the edge of the bed with both hands, an assistant stands on the upper end of the patient’s healthy side, holds the patient’s armpits with both palms and pulls forward to fix the patient’s upper body. The other assistant stood at the other end of the bed and held the ankle of the affected side with both hands, pulling backward. The doctor stands on the affected side of the patient, takes the abdomen of the thumb of one hand as the attachment point, presses the paracarpal pressure point or its small joint misalignment next to the spinous process, and pushes the top to the healthy side; the forearm of the other hand encircles the healthy side of the lower limb, makes the knee attach to the inner elbow of the operator, and tracts slowly to the back and upward, while wrenching slowly and forcefully to the back and upward, until the patient tolerates it, then then suddenly tug with a little force to the top. At this time, the operator’s thumb and the patient’s waist feel a “creak” at the same time, to show that the purpose. The posterior wrenching method under antitraction is a unique technique with a large force and a wide range of application. It is clinically applicable to disorders caused by soft tissue injury and bone and joint lesions of the lumbar region, including acute and chronic lumbar injury, lumbar degenerative spondylitis, lumbar synostosis, lumbar spinal stenosis and so on. Apply the lumbar counter traction force when appropriate. If it is too large, it is easy to hurt the normal muscles and tendons and increase the patient’s pain; if it is too small, it cannot achieve the treatment purpose. The size and manner of force should be determined according to the patient’s age, gender, body type, physique and disease duration. Generally speaking, young and healthy people, traction force should be large. Older and weaker people, the force should be small; male patients, the traction force is large; female patients, the force should be small. The body is strong and obese, the traction force is large, the body is thin, the force should be smaller; the short course of the disease, the traction force should be larger, the long course of the disease, the traction force should gradually increase, and finally the traction force can be slightly larger. In short, the size of the traction force should be mastered as the patient can tolerate, in order to achieve the degree of widening the vertebral space.
