Ankylosing spondylitis is a connective tissue disease, a systemic disease that affects multiple organs and systems. The disease usually involves the sacroiliac joints at the beginning. Patients have lower back pain, stiffness in the morning, and limited bending. The spine becomes more and more difficult to move, and eventually becomes hunchback deformity, which can be accompanied by scoliosis and, in severe cases, flexion ankylosis of the neck. Not only can they not walk on the floor, but they also have difficulty in daily life such as sitting, lying down and putting on shoes and socks. Respiratory differential test: To check the patient’s thoracic mobility, the patient stands upright and uses a graduated soft ruler to measure the difference between the patient’s chest circumference during deep exhalation and deep inhalation at the level of the patient’s glabella (the lower edge of the woman’s breast), less than 3.5 cm is diagnostic. The HLA-B positivity rate for ankylosing spondylitis is higher than 80%. The typical radiographic changes are: widening of the sacroiliac joint space with jagged edges, followed by blurring and eventually bony ankylosis, “square vertebral” changes, blurring of the intervertebral joint space, followed by fusion, and “bamboo joints” due to extensive ossification of the paravertebral and intervertebral ligaments. “The vertebral body is osteoporotic but still square in shape The hip joint cartilage is destroyed and the gap is narrowed and bony fusion occurs Based on the above history Clinical symptoms (pain and limitation of joint movement, ankylosis, combined with accelerated blood sedimentation, negative rheumatoid factor and positive HLA-B, the diagnosis is not difficult. There is no single theory that can elucidate the full etiology of ankylosing spondylitis, but it is thought that the disease may develop on a genetic basis with the influence of infection and other factors, but it is not related to the so-called acupuncture points. Treatment: The goal of treatment is to control inflammation, relieve symptoms, and prevent spinal joint deformities. When pain cannot be controlled, small doses of adrenal cortical steroids can be applied, but they should not be used for a long time. These drugs need to be used for about 3 months before their effects occur and are called chronic-acting drugs. Patients should pay attention to maintain the correct posture when sitting or lying down and not to sleep on too soft a bed so that hunchback, neck, hip and knee deformities do not occur. 3, has a serious hunchback deformity, if the disease has stopped or basically stopped the development of temperature, blood sedimentation is close to normal, and at the same time, the heart and lung function are good, then can be performed osteotomy, that is, in the lumbar ~ the posterior attachment of the vertebrae, including the vertebral plate, spinous process and articular processes for wedge-shaped excision, and then reset and internal fixation can also be performed in multiple planes of osteotomy, can restore the patient to look forward, we use these methods to cure many patients, the effect is very good (Illustration. Hip and knee joints are fused with flexion deformity. Depending on the patient’s condition, artificial arthroplasty or osteotomy can be performed, and because the synovial membrane of my joint is removed during surgery, the blood sedimentation is normalized soon after surgery.
