Intense alterations of mineral and bone metabolism are prevalent in chronic kidney disease (CKD) and represent an important cause of morbidity and decreased quality of life. These disor-ders have traditionally been defined as renal osteodystrophy and classified based on bone biop-sy, but due to a lack of bone biopsy data and validated radiological methods to evaluate bone morphology in children, it has been difficult to adequately evaluate renal osteodystrophy in pe-diatric CKD. This has led to suboptimal management of bone disorders in children. CKD-mineral and bone disorder (CKD-MBD) is a new term used to describe a systemic disorder of mineral and bone metabolism as a result of CKD. CKD-MBD is a triad of biochemical imbalances of cal-cium, phosphate, parathyroid hormone and vitamin D, bone abnormalities and soft tissue calci-fication. This literature review aims to explore the pathogenesis, diagnostic approach, and treat-ment of CKD-MBD in children and the specific consequences of renal osteodystrophy on growing skeleton, with a specific focus on the biological basis of this peculiar condition.
