[Kidney and bone update : the 5-year history and future of CKD-MBD. Disorders of musculoskeletal system in CKD ; bone fracture and periarticular calcification].

Chronic kidney disease-mineral and bone disorder (CKD-MBD) affects life expectancy through vascular calcification, and impairs patient's activity of daily living (ADL) and quality of life (QOL) through bone fracture and periarticular calcification. In CKD patients, vitamin D deficiency and secondary hyperparathyroidism impairs bone strength, and muscle dysfunction related to vitamin D deficiency also causes easy fall, leading to the high risk of bone fracture. Bone fracture not only aggravates ADL and QOL but increases the risk of mortality. Periarticular calcification such as tumoral calcinosis in relation to CKD-MBD causes restricted range of articular motion, leading to the deterioration of patient's ADL and QOL. Because bone fragility and tumoral calcinosis occurs in relation to CKD-MBD, the appropriate management of CKD-MBD is madatory.
