Ankylosing spondylitis which can damage bone and joint

(1) Spinal: medical often called "axis joints" that is, the people said, "Beam bone", we can see that it pillars in the body from the role. It is constituted by a vertebral, and on some of these vertebral ligament lOOO root and more than 140 muscles connect into resilient spine. It is divided into the cervical, thoracic, lumbar, sacral vertebral and Sacrococcygeal. Cervical task is to support the head, people can rise and bow to the old, and had its credit; connected to the thoracic spine and ribs formed a solid thorax, which is the protection of visceral pleural "castle" in the lumbar spine is "backbone", which bear most of the body weight and sacral vertebral Sacrococcygeal in human evolution in the course of the degradation, there are great differences in individual, and iliac sacral vertebral formation sacroiliac joints, cartilage mainly rely on connecting to participate in a pelvis, sacroiliac joints is fretting joints, ankylosing spondylitis is the most common violations of the joints. (2) limb joints: medical habit called "peripheral joints," including large and small articular joints. Large joints including the shoulder, elbow, wrist, hip, knee, ankle; usually refers to small joints of the hand, foot and joint.

(3) the structure of joint activities: these two joints are included, the main structure of ligaments, the joint capsule, the muscles around the joints and tendons, cartilage, bone cavity, synovial, synovial fluid, etc.. Nutritious normal synovial fluid and lubrication of articular cartilage role. When a joint inflammation or injury, there is intra-articular effusion due to joint swelling, affecting the function of joints. The bone and joint ankylosing spondylitis is a good site. Bone and joint guarantor of the quality of life is very important, it should be small changes in any We must pay close attention.
