A 57 y/o male is on hemodialysis for CRF. Which of the following metabolic derangements can be anticipated?
A- hypercalcemia
B- hypophosphatemia
C- osteomalacia
D- Vit D excess
E- Hypoparathyroidism

This is a remebered question I got from some where. The given answer is c- osteomalacia. I would like to know if osteomalacia is a mistype when osteodystrophy should be in the answer choice. Or is it that the two terms are interchangeable?

Renal osteodystrophy is a global term applied to all pathologic features of bone in patients with renal failure. The primary retention of phosphate by abnormal kidneys results in hyperphosphatemia, which causes hypocalcemia, resulting in secondary hyperparathyroidism.Therefore, the spectrum of clinical and radiographic findings in renal osteodystrophy may be a manifestation of any of these disorders.


Osteomalacia is a disorder of bone that results from hypomineralization (VIT. D deficiency) following the cessation of bone growth. In contrast to rickets, which affects mineralization of growing bones, osteomalacia does not affect the growth plates; however, hypomineralization of trabecular and cortical bone occurs.

Osteomalacia may be part of the spectrum of osseous abnormalities that can be observed in patients with chronic renal insufficiency. This condition is referred to as renal osteodystrophy.


well Osteomalacia seems to be the likely answer ...
