| Ankylosing spondylitis is one of the common rheumatic diseases. It is an arthritis that mainly affects the axial joints. The axial joints may become ossified in the middle and late stage, leading to the stiffness and deformity of the spinal joints. Osteoporosis is one of the common secondary diseases, which aggravates joint deformation or leads to vertebral fractures. However, in the actual treatment process, the secondary osteoporosis of ankylosing spondylitis has not attracted enough attention, and there is a lack of a clear treatment method and clinical guideline. According to TCM theory, it is believed that the kidney dominates the bone. If the kidney essence is sufficient, the bone is strong, If the kidney essence is deficient, the bone marrow is empty. The obstruction of the artery leads to ankylosing spondylitis, bone marrow loss and bone loss, and secondary osteoporosis. Therefore, in this paper, the stage treatment of this disease is guided by the kidney dominating bone theory, and the intervention effect of traditional Chinese medicine on osteoporosis secondary to ankylosing spondylitis is expounded from the perspective of this theory, reflecting its clinical application value. |
