SPINAL CALCIUM CHANGES WITH 1α‐HYDROXYVITAMIN D3

Abstract
SUMMARY: During treatment of renal osteodystrophy with lα‐hydroxyvitamin D3 in eleven patients, regional changes in the skeleton have been compared with long‐term calcium balance as assessed by whole‐body calcium. Radial bone changes did not correlate well with calcium balance, but spinal calcium changes were of a similar magnitude when changes were large. Bone alkaline phosphate changes correlated well with changes in spinal calcium, but less well with changes in radial bone density.
