The third lumbar vertebra is the center of lumbar activity and has the longest transverse process, the tip of which is susceptible to injury by external forces. If symptoms such as lumbago and lower limb pain and lumbar mobility impairment occur due to acute and chronic injury, it is called third lumbar transverse process syndrome. In patients with lumbar strain, the third lumbar transverse process syndrome is more common. Clinically, it is common to have similar lesions at the tip of the lumbar 3 and 4 transverse processes, so some people classify the third lumbar transverse process syndrome as an intertransverse process syndrome. This disease is most often seen in young people with long and lean body types. This disease belongs to the category of “injury to tendons” in Chinese medicine. The internal cause of this disease is the high stress on the transverse processes of the third lumbar vertebra due to anatomical and biomechanical factors. When the lumbar spine is flexed, bent sideways and rotated, the soft tissue attached to the tip of the transverse process is prone to pathological changes such as muscle tearing and rupture of small blood vessels, causing tissue edema, compression and stimulation of the lateral branch of the posterior branch of the lumbar nerve, causing spasm of the innervated muscles and the formation of fibrosis and scar-like tissue in the area, resulting in a series of symptoms. The anatomical variation of the transverse process of the third lumbar vertebra, such as excessive length or asymmetry on both sides, is also one of the internal causes. Cold stimulation can also induce the disease. The disease can be soreness and pain in the lumbar region or severe pain with limited movement, which can affect daily life and work in severe cases. The pain can reach the buttocks and the front of the thighs. There is no pain when the back is tilted back, and bending to the opposite side is limited. The important sign is the outer edge of the transverse process of the third lumbar vertebra, which corresponds to 4 cm next to the spinous process of the third lumbar vertebra, and the tip of the transverse process can be palpated with obvious pressure pain and restrictive muscle tension or muscle spasm, especially in long and thin patients. When pressed, the pain radiates to the thigh and knee due to the stimulation of the second lumbar nerve branch. Radiographs show a long transverse process of the third lumbar vertebra. The pain and pressure pain disappeared after the pressure point was injected with 10-20mL of 1% or 0.5% procaine. Based on the pressure point and the effective injection of procaine, and combined with the medical history, symptoms and other signs can identify other disorders caused by low back pain. Treatment principles: mainly weight reduction, attention to rest, medication, physiotherapy assistance. (1) General treatment: In the acute stage of low back pain attack, appropriate bed rest is advocated to prevent further development of the disease, and bed rest with a hard board is appropriate. In severe cases, sandbag braking can be placed on both sides of the waist. (2) Western medicine treatment: often oral painkillers such as ibuprofen, fenbid, anti-inflammatory pain, etc. can also be used for local spraying, or hormone plus procaine pain point closure. (3) Chinese herbal medicine treatment: soup can be selected from the experienced formula: Astragalus, Radix et Rhizoma, Atractylodes Macrocephala, Radix Angelicae Sinensis, Pericarpium Citri Reticulatae, Radix et Rhizoma, Glycyrrhiza Uralensis, Qinjiu, Rhizoma Ligustici Chuanxiong, Rhizoma Peach, Rhizoma Safflower, Fructus Schisandrae, Radix Aconiti, Radix Achyranthes Bidentatae, Radix et Rhizoma Dioscorea, Radix et Rhizoma Tuh. Decoction with water, twice a day, 150ml each time. topical medicine can be used nano-acupuncture point compress, dog skin paste, musk strong bone paste can be applied to the affected area or acupuncture point. Let the patient stand upright with his back against the wall, then the doctor assist the patient to bend, when the patient can no longer continue to bend down, the doctor holds the patient’s abdomen with one hand and presses the patient’s back with the other hand, popping the pressure, the patient can bend the waist to normal, then let the patient stand upright, the doctor holds the patient to make his back stretch, when the patient can not continue to stretch the back the doctor that is the trend to make the patient to the back overstretch a little, the end of the technique.
