Ankylosing spondylitis (AS) is a rheumatic disease characterized by sacroiliac arthritis and chronic inflammation of the spine that affects mainly young and middle-aged men, causing low back pain, morning stiffness, and limited movement of the thoracolumbar spine. Although the incidence is low, the disability rate is high, and there is no specific treatment. The main clinical manifestations are joint symptoms (low back pain, morning stiffness, restricted movement of the lumbar spine in all directions, and reduced thoracic movement) and extra-articular manifestations (weakness, anemia, and muscle soreness). The early symptoms of this disease are insidious, and some of them only have discomfort and stiffness in the low back without obvious pain, which is easily confused with chronic pain in the low back and leads to misdiagnosis and mistreatment. Some are accompanied by back and leg pain, and it is also difficult to distinguish from mild herniation of the lumbar disc. Some of them have a little stiffness in the lower back in the morning and are comfortable after a few moments of activity, which is easily confused with lumbar muscle strain. Therefore, when the clinical discomfort of low back pain does not improve significantly after more systematic treatment, the possibility of ankylosing spondylitis should be considered, especially in patients with a family history of low back pain and a history of hunchback. Early clinical examination is very important, especially sacroiliac joint examination should be more careful, such as sacroiliac joint pressure pain, all kinds of tests that can cause sacroiliac joint pain should not be missed, once sacroiliac joint pain is found, further sacroiliac joint lesions should be carried out to confirm the diagnosis.
