Many young people have been suffering from back pain for many years, and it takes a lot of financial and human resources to get a diagnosis of “spondyloarthropathy”. Some people have been diagnosed with the disease for more than 10 years, and their spine and hip joints have become deformed and ankylosed, and they have lost their ability to work. The main reason for this is that most people (especially most doctors) do not know enough about “spondyloarthropathies”. Often, many patients, even in the rheumatology department upstairs, downstairs or next to the department repeatedly seek treatment, but a step away, but like a world of difference, has been treated as “lumbar muscle strain”, “herniated disc”, ” Sciatica”, “osteophytes”, “kidney deficiency” and so on, but not into the “spondylolisthesis” thinking after all. The majority of patients are diagnosed in a timely manner only after the appearance of spinal joint ankylosis, which becomes very typical of “ankylosing spondylitis”. In fact, by this time, a better time for treatment has been missed. Seronegative spondyloarthropathies, or spondyloarthropathies, are a group of diseases that have the following common features: the basic pathological change is tendonitis; sacroiliac arthritis often appears early in the course of the disease and can occur essentially throughout the course of the disease; they can cause inflammation of the spine and some large joints (such as the hip) and eventually even develop into ankylosis; most have the HLA-B27 gene; they are easily accompanied by eye (iridocyclitis ), intestinal mucosa (Crohn’s disease, ulcerative colitis), skin and nails (psoriasis, or psoriasis) and genitourinary tract (urethritis and, in women, cervicitis); there is a family tendency to develop the disease. The specific etiology and pathogenesis of these diseases have not yet been clarified, and it is expedient to call them spondyloarthropathies, and because of this status, it is not easy for non-specialists to recognize these diseases as familiar as “gastritis” and “pneumonia”. Spondyloarthropathies have the above-mentioned “commonalities” and different “personalities”, and are currently classified according to their different characteristics: ankylosing spondylitis, reactive arthritis, inflammatory bowel disease arthritis, psoriatic arthritis, undifferentiated spondyloarthropathy, juvenile Since 2009, there have been various diagnostic classifications of spondyloarthropathies of the medial and peripheral types to allow for earlier diagnosis. When low back and hip pain of the following nature occurs, it is important to pay attention to this type of disease: 1. it develops before the age of 40, especially in men; 2. it starts gradually (often the exact time of onset is not remembered), or it suddenly appears soon after diarrhea, urethritis, cervicitis, gynecological surgery, childbirth, etc. (or swelling and pain in one or two large joints of the lower extremities); 4. the pain is obvious after a long rest period (especially after sleeping until The pain is obvious after a long time of rest (especially in the second half of the night, even when waking up in pain and unable to sleep), and can be relieved after getting up and moving slowly; 5. When getting up in the morning, the back is stiff, even unable to sit up directly, and needs to be turned over slowly to get up. When there is back pain of the above nature, accompanied by: 1. recurrent red eyes, chronic diarrhea, heel pain, parasternal joint pain, rash with white flakes (psoriasis), etc.; 2. similar diseases among relatives of closer blood relations, etc., then it is more important to pay attention.
