The third lumbar vertebra is the center of lumbar spine activity, with the longest transverse process, and its tip is susceptible to injuries caused by external forces. Symptoms such as lumbago and lower limb pain, and lumbar mobility disorders due to acute and chronic injuries are referred to as transverse third lumbar vertebra syndrome. Among the patients with lumbar muscle strain injury, the third lumbar transverse process syndrome is more common. Clinically, it is common that the tip of the transverse processes of lumbar 3 and lumbar 4 have lesions similar to those of the transverse processes of lumbar 3, so some people categorize the third lumbar transverse process syndrome as intertransverse process syndrome. This disease is most common in long and thin young people. This disease belongs to the category of “injured tendon” in Chinese medicine. The internal cause of this disease is the high stress on the transverse process of the third lumbar vertebra due to anatomical and biomechanical factors. When the lumbar spine bends forward, sideways and rotates, it is easy to cause the soft tissue attached to the tip of the transverse process to have pathological changes such as muscle tears and small blood vessel ruptures, which causes tissue edema, compresses and stimulates the posterior branch of lumbar nerve, causing spasm of the innervated muscles, and the formation of fibrosis and scar-like tissues locally, resulting in a series of symptoms. Anatomical variants such as excessive length of the transverse process of the third lumbar vertebra or asymmetry on both sides are also one of the internal causes. Cold stimulation can also induce the disease. Chinese medicine believes that it is caused by inborn insufficiency of endowment and exposure to cold and strain. [Identification] The pain in the lumbar region is stagnant, aggravated by cold or exertion, and the pain sometimes radiates to the buttocks, the ipsilateral adductor muscles, and the anterior aspect of the thighs, but does not go beyond the knee joint. The tip of the transverse process of the third lumbar vertebra has obvious pressure and pain, and can be touched with myofascial nodules or striated material; lumbar activities are slightly restricted. x-ray film generally has no abnormal findings, and a small number of third lumbar vertebra transverse process can be seen to be obviously too long or asymmetric. Clinical manifestations: The disease can be lumbar pain, or severe pain, activity is limited, serious impact on daily life and work. The pain can reach the buttocks and the front of the thigh. The pain can reach the buttocks and the front of the thighs. It is painless to tilt the back of the waist and limited to bend to the opposite side. The important sign is the outer edge of the transverse process of the third lumbar vertebra, which is equivalent to 4cm beside the spinous process of the third lumbar vertebra, and the tip of the transverse process can be palpated with obvious compression pain and limited muscle tension or muscle spasm, especially in long and thin patients. When pressed, the second lumbar nerve branch is stimulated and causes radiating pain to the thigh and knee. X-ray radiographs show a long transverse process of the third lumbar vertebra. After injection of 10% or 0.5% procaine 10-20mL at the pressure point, the pain and pressure disappeared. According to the pressure point and the injection of procaine is effective, and combined with the history, symptoms and other signs can be identified other disorders caused by low back pain. The main thing is to reduce weight bearing, pay attention to rest, medication, physical therapy assistance. [Treatment principle] (1) general treatment: in the acute stage of the attack of low back pain, advocate appropriate bed rest, in order to prevent the further development of the condition, bed to hard board is appropriate. Severe cases can be placed on both sides of the waist sandbag braking. (2) Western medicine treatment: often oral painkillers such as ibuprofen, fenbid, anti-inflammatory pain, etc., can also be used to good fast local spray, or hormone plus procaine pain point closed. (3) Chinese medicine treatment: Chinese patent medicine can choose ginseng spleen pill, tonifying the middle and benefiting the qi pill, strong kidney tablets, etc. with the single living parasitic pill, blood circulation pain capsule and other treatments. Water decoction, twice a day, each time 150 ml. external medicine can be used nano acupoint dressing, dog skin cream, force pulling cold San, musk strong bone paste on the affected area or acupoints can be. Let the patient’s back against the wall upright, and then the doctor to assist the patient to bend over, when the patient can not continue to bend over down, the doctor a hand to hold the patient’s abdomen, a hand pressure on the patient’s back, popping pressure, the patient that will be able to bend over to normal, and then let the patient upright, the doctor to hold the patient to make the back stretching, when can not continue to stretch the back of the doctor that is, along with the trend of making the patient to the back of the back to overstretch a little bit, manipulation end. Treatment measures] For mild symptoms, acupuncture, massage, physiotherapy, external medication and oral anti-inflammatory drugs are effective.
