Kidney deficiency is the root of its pathogenesis: Studies have shown that the bone density and mineral content of patients with kidney deficiency are significantly lower than those of healthy people of the same age. As the incidence of kidney deficiency gradually increases with age, the bone mineral content in human bones also gradually decreases. The incidence of fractures in the elderly increases significantly with the incidence of kidney deficiency. Spleen deficiency is an important factor: If the spleen is deficient, there is a lack of qi and blood, resulting in a loss of bone marrow nourishment. In addition, the spleen is the base of the posterior, and the kidney is the base of the anterior, and the kidney essence depends on the nourishment of the spleen essence to be replenished continuously. If the spleen is not transported and transformed, the spleen essence is insufficient, the kidney essence will be lacking, resulting in the loss of kidney essence and the loss of nourishment for the bones, which will eventually lead to weak bones and osteoporosis. Bone pain is the most common and main clinical symptom, with low back pain being the most common, and the pain is fixed and does not move. It is clearly pointed out in the “Correction of the Medical Forest” that “pain that does not move” or “all paralysis pain” must have blood stasis, which is both an important pathological basis and a pathological product of this disease. Osteoporosis causes fracture of bone microstructure trabeculae, which will inevitably damage blood channels and lead to blood stasis in the bone.
