Renal osteodystrophy is defined as an alteration of bone in patients with chronic kidney disease (CKD).[1] It is one measure of the skeletal component of the systemic disorder of chronic kidney disease-mineral and bone disorder (CKD-MBD).[1][2][3] The term "renal osteodystrophy" was coined in 1943,[4] 60 years after an association was identified between bone disease and kidney failure.[5]
The types of renal osteodystrophy[6] have traditionally been defined on the basis of bone turnover and mineralization:
1) mild, slight increase in turnover and normal mineralization;
2) osteitis fibrosa, increased turnover and normal mineralization;
3) osteomalacia, decreased turnover and abnormal mineralization;
4) adynamic, decreased turnover and acellularity; and,
5) mixed, increased turnover with abnormal mineralization.[1]
A Kidney Disease: Improving Global Outcomes (KDIGO) report has suggested that bone biopsies in patients with CKD should be characterized by determining bone turnover, mineralization, and volume (TMV system).[2]
On the other hand, CKD-MBD is defined as a systemic disorder of mineral and bone metabolism due to CKD manifested by either one or a combination of:
1) abnormalities of calcium, phosphorus, PTH, or vitamin D metabolism;
2) abnormalities in bone turnover, mineralization, volume, linear growth, or strength (renal osteodystrophy); and
3) vascular or other soft-tissue calcification.[1][7]
