What is lumbar intervertebral discogenic low back pain: the current reference to discogenic low back pain (discogenic back pain) was first proposed by Crock, clinically it is an extremely common and frequent disease, it is a chronic low back pain caused by intravertebral disc disorders (IDD), such as degeneration, fibrous annulus enthesopathica, intervertebral disc inflammation, etc. that stimulate pain receptors within the intervertebral discs, not accompanied by radicular symptoms, without nerve root compression or radiographic evidence of excessive displacement of vertebral segments, it can be described as chemically mediated low back pain. radiographic evidence of excessive vertebral segmental displacement, and can be described as chemically mediated discogenic pain. It is currently believed that chemical irritation, in addition to mechanical compression, is the main cause of discogenic pain; the pain originates primarily from lesions within the disc itself. Mechanisms: (1) rupture of the nucleus pulposus and annulus fibrosus, (2) abnormal distribution of nerves within the intervertebral disc, (3) stimulation of chemical substances in the intervertebral disc, (4) changes in mechanical pressure within the intervertebral disc, (5) epidural inflammation and chemical radiculitis. Clinical features: The most important feature is the decrease of sitting tolerance, the pain is often aggravated when sitting, and the patient usually can only sit for 20-30 minutes; the pain is mainly located in the lumbar region, the lumbosacral spinous processes, the posterior iliac region, the buttocks, the groin, the anterior femur, the posterior femur, the greater trochanter, and so on; the patient often needs to hold the thighs in order to sit in a chair or to stand up from a chair; although the discogenic lumbago can be accompanied by leg pain, but the leg pain is often not clearly defined, and it is often not accompanied by a leg pain. Although discogenic low back pain can be accompanied by leg pain, the leg pain is often not clearly defined, often difficult to express, and most often complains of a feeling of heaviness or cramps in the buttocks and lower extremities; and the pain area lacks the characteristics of the distribution of the nerves, and the neurological examination is normal, there is no skin sensory sensitization or deficits, and it can sometimes radiate to the lower extremities, and a significant proportion of patients suffer from pain in the lower extremities below the knee joints, but there are no diagnostic specific signs present; and the majority of patients can have a long recurrent low back pain. Most of the patients may have recurrent lumbar pain for a long time, which is aggravated by exertion or prolonged standing, and also aggravated by cold; on the contrary, lumbar pain is alleviated after resting, especially after lying down in bed, and after keeping warm. Examination: (1) X-ray film: generally need to take lumbar vertebra positive and lateral position and over-extension Guo flexion flat film; (2) CT examination: (3) MRI examination (the most effective): can clearly show the degree of intervertebral disc degeneration, such as the “black disc”, the posterior edge of the vertebral body, such as the signs of high signal area. Self-adjustment treatment and prevention: (1) Eat a balanced diet, avoid obesity: protein, fiber content should be high, fat, cholesterol should be low, quit smoking and alcohol; (2) learn to relax, reduce tension: life, work, pay attention to the combination of work and rest, maintain the correct posture, should not be sedentary and long standing, before strenuous physical activities to do the preparatory activities; (3) bed rest, it is advisable to choose a hard board bed, to maintain the physiological curvature of the spine; (4) (4) avoid cold and keep warm; (5) usually should strengthen the lumbar back muscle function exercise, improve the stability of the lumbar spine.
