Shmorl's hernia) — gryzhepodobny protrusions of a pulpozny (jellylike) kernel of an intervertebral disk. Are described by K. Shmorl.

The rupture of a plate of a hyaline cartilage with the subsequent loss of a pulpozny kernel of an intervertebral disk can happen at curvatures, compression perelo-

A certain role in Sh.'s education at. play also processes of a physiological resorption of a cartilaginous part of an intervertebral disk. By the end of the first year of life in the plate of a hyaline cartilage forming a support for a pulpozny kernel proliferative processes are noted. In the subsequent cellular elements in different departments of an intervertebral disk disappear. These changes lead to reduction of durability of an intervertebral disk that is the contributing factor for nodulation of Shmorl at children's and youthful age.
