With the gradual improvement of medical auxiliary examination technology, more and more high-definition and high-resolution auxiliary examinations are applied to the clinic, which in some aspects provide great help to clinicians in diagnosis and treatment. However, in today’s advanced medical science and technology, the most basic X-ray has gradually faded out of the public’s view, and even lost the attention of some clinicians. In the eight years of my contact with painful diseases, I found that in the diagnosis and treatment of spinal and joint pain, X-ray examination has an irreplaceable role. Liu Lin, Department of Pain, Henan Provincial People’s Hospital The spine is the central axis pillar of the human body, with a complex structure and many functions, its main role are: (1) the human body is in a variety of positions to support the head and torso, and the load load to the pelvis. (2) To enable the head and trunk to accomplish a large range of physiological activities in three-dimensional space. (3) To protect the spinal cord and organs in the thorax, abdomen, lumbar and pelvic cavities from injury. At present, with the development of medical technology, especially the popularization of high-resolution CT and MRI, non-invasive diagnosis and treatment of spinal local spinal cord, nerve roots, muscle ligaments has provided a qualitative leap, but in years of outpatient clinic treatment, it is found that a lot of patients tend to improve a lot of tests on their own before the medical treatment, such as MRI, CT, the patient feels: the more expensive the better the examination, the clearer the view, and the traditional X-ray becomes This is a misunderstanding, each test has its own value, X-ray in clinical diagnostic and treatment activities in the application of many years, there is indeed an irreplaceable role. X-ray reflection of the overall structure of the spine is irreplaceable, traditional Chinese medicine that: “the spine is a whole, in a whole three-dimensional spatial activity, a lesion, may affect the whole range of physiological activities of the abnormal.” In the cervical and lumbar spine pain diagnosis and treatment activities, it is not a headache and foot pain. Certain lesions in the spine can cause manifestations in distant reflex zones, which require a holistic view of the overall shape of the spine, something that modern CT and MRI cannot show. In treatment, pain doctors often need to puncture, loosen and reset some tiny joints. X-ray can help doctors to find out the body markers of the lesion location directly on the body surface and guide them to perform clinical invasive operations. In the later stage of rehabilitation training, the overall biomechanical analysis, X-ray can help patients find out the focus of rehabilitation training, the development of line-specific rehabilitation training program.
