Renal bone disease, also known as renal osteodystrophy, is caused by kidney disease resulting in renal insufficiency or renal failure, resulting in abnormal calcium and phosphorus metabolism in the body, resulting in high blood phosphorus and low blood calcium, which can stimulate the body to secrete a large amount of parathyroid hormone, resulting in the release of a large amount of bone calcium, resulting in bone softening and decalcification. Kidney disease can also cause a decrease in active vitamin D3 in the body, which is not conducive to bone calcification and mineralization, coupled with hyperparathyroid hormone, resulting in a large amount of bone decalcification, bone softening, joint pain, periarticular tendonitis and a series of other symptoms, which can also produce systemic symptoms, as well as lead to an imbalance in the body’s acid-base balance and produce effects on bone metabolism.
