[Magnesium and several metabolic osteopathies].

Magnesium is a constituant of the bone minerals. Changes in its intra-bone distribution have repercussions on the distribution of calcium and on the hormonal regulators of calcium. The importance of magnesium in bone pathology is far from being completely elucidated. Certain factors are now commonly admitted, for example the inhibition of the parathyroid secretion during magnesium deficiency. Others merit more complete and thorough study, it being highly unlikely that the bone is unaffected by changes in the organic magnesium content, given the multiple roles that magnesium plays in the bone. In this report, the authors provide well-known data on the physiology of magnesium, and discuss some of the relationships between magnesium disturbances and certain osteopathies.
