Spondylolisthesis of the axis vertebra [PDF]
American Journal of Roentgenology, 1977 The second cervical vertebra, or axis, is readily distinguished from all others by a toothlike projection from the upper end of the body, the dens (fig. 1 ). Anteriorly the dens has a facet for articulation with the corresponding facet on the innermost surface of the anterior arch of the atlas.

Advanced Science, EarlyView.Local stress concentration disrupts metabolic homeostasis and induces inflammation in the nucleus pulposus (NP), thereby accelerating intervertebral disc degeneration (IDD). A biomimetic HA/ChS hydrogel millimeter sphere (ChS@HM) is developed to enable synergistic stress dispersion and sustained hydration lubrication.
