Ankylosing spondylitis is a disease characterized by inflammation of the ankle joint and spinal attachment point. Strong association with HLA-B27. Certain microorganisms, such as Klebsiella, have a common antigen with the susceptible tissue and can trigger an abnormal immune response. It is a chronic inflammatory disease characterized by large joints of the extremities, as well as fibrosis and ossification of connective tissue near the annulus fibrosus and its ankylosis. About one-third of AS patients will have different degrees of hip joint disease, from the hips, groin, inner thighs, buttocks, pain, and more intense, followed by limited hip joint activity, joint muscle atrophy, and finally bony rigidity ( With severe osteoporosis), living and living difficulties, more than 85% of patients with AS disability are caused by hip disease. Therefore, patients with tonic must be alert to the disabled killer: hip involvement!
What is the hip joint?
The hip joint consists of the femoral head and the acetabulum and belongs to the ankle joint. In the acetabulum, only the lunate surface is covered with articular cartilage. The acetabular fossa is filled with fat. It is also called Haversian gland. It can be squeezed or inhaled with the increase and decrease of intra-articular pressure to maintain the balance of intra-articular pressure. There is a joint rim on the edge of the acetabulum. Deepens the depth of the socket. On the acetabular notch, there is a transverse ligament of the acetabulum, and a hole is formed in the incision, and nerves, blood vessels, etc. pass through.
Why is it hip involvement?
The hip joint, commonly known as the ankle joint, acts as the most important joint in the human body. It helps people stand and achieve flexion, extension, rotation, and rotation. The hip joint is the largest weight-bearing joint of the human body and plays an irreplaceable role in various movements. For this reason, it is also highly vulnerable to trauma and disease. Inflammation of the hip joint does not lead to the formation of new bone, but it is invasive and damages the joint structure. – T cell infiltration, vascular proliferation and osteoclast increase in the cartilage surface and subchondral bone. It is speculated that the mechanism is activation. Osteoblasts induce the expression of tumor necrosis factor (TNF), which leads to bone destruction.
Most people are relatively unfamiliar with this disease, and due to lack of basic understanding, they may miss the best treatment opportunity. In fact, from the name of the disease, it is a chronic disease with the spine as the main lesion, but it also affects the hip joint and causes different degrees of eye, lung and muscle lesions. When the disease is seriously invaded by the hip joint, the hip joint will be as dead as the iron plate, the patient’s activity will be limited, and the ultimate life cannot be taken care of.
Ankylosing spondylitis has a high incidence of hip joint disease and is highly disabling. It needs to be highly valued. Do not blindly seek medical treatment, we must choose a professional hospital for scientific and standardized diagnosis and treatment, in order to reduce the disability rate of ankylosing spondylitis.
