Calcification in the Intervertebral Disk

Naturevolume 199pages612613 (1963) | Download Citation



THE human intervertebral disk is a structure in which degenerative changes are very common, often appearing as early as the third decade. Consequently it is not surprising that foci of calcification are frequently found in the intervertebral disks of apparently normal subjects. However, little information is available on the exact nature of the mineral phases and the possible significance that these may bear in relation to the underlying changes in the matrix. At present X-ray diffraction is the most sensitive method for identification of the various calcium compounds which can occur in the body.
