It is ring-like and consists of an anterior arch, posterior arch, and two lateral masses. The axis (C2) forms the pivot on which the atlas rotates. The most distinctive characteristic of this bone is the strong odontoid process (dens) that rises perpendicularly from the upper surface of the body and articulates with C1.
C1 is also called the atlas, and C2 is also called the axis. The structure of these vertebrae is the reason why the neck and head have a large range of motion. The atlanto-occipital joint allows the skull to move up and down, while the atlanto-axial joint allows the upper neck to twist left and right. The axis also sits upon the first ...
Bilateral C2 pars fractures are known as a variant of the hangman's fracture. On an anterior oblique radiograph of the lumbar spine , the pars is the neck of the imaginary Scottie dog; the Scottie dog's eye is the pedicle, [ 3 ] its hindlegs the spinous process, its nose the transverse process, its ear the superior articular facet and its ...
[1] A disc protrusion is a medical condition that can occur in some vertebrates, including humans, in which the outermost layers of the anulus fibrosus of the intervertebral discs of the spine are intact but bulge when one or more of the discs are under pressure.
There are three atlanto-axial joints: one median and two lateral: [2] The median atlanto-axial joint is sometimes considered a triple joint: [3] one between the posterior surface of the anterior arch of atlas and the front of the odontoid process; one between the anterior surface of the ligament and the back of the odontoid process
In the cervical spine, a symptomatic postero-lateral herniation between two vertebrae will impinge on the nerve which exits the spinal canal between those two vertebrae on that side. [21] So, for example, a right postero-lateral herniation of the disc between vertebrae C5 and C6 will impinge on the right C6 spinal nerve.
Lateral displacement is called lateral listhesis [4] or laterolisthesis. [ 5 ] A hangman's fracture is a specific type of spondylolisthesis where the second cervical vertebra (C2) is displaced anteriorly relative to the C3 vertebra due to fractures of the C2 vertebra's pedicles .
