The anterior longitudinal ligament extends superoinferiorly between the basiocciput of the skull and the anterior tubercle of the atlas (cervical certebra C1) superiorly, and the superior part of the sacrum inferiorly; [1] inferiorly, it ends at the sacral promontory. [2] It broadens inferiorly. [1]
The anterior longitudinal ligament and posterior longitudinal ligament are both illustrated in this image; the anterior longitudinal ligament is to the far left, while the posterior longitudinal ligament is left of the center. The longitudinal ligaments are two sets of ligaments that run along the spine. These are:
In the spine, there is bone formation along the anterior longitudinal ligament and sometimes the posterior longitudinal ligament, which may lead to partial or complete fusion of adjacent vertebrae. The facet and sacroiliac joints tend to be uninvolved. The thoracic spine is the most common level involved. [2]
Tears are almost always posterolateral (on the back sides) owing to relative narrowness of the posterior longitudinal ligament relative to the anterior longitudinal ligament. [3] A tear in the disc ring may result in the release of chemicals causing inflammation, which can result in severe pain even in the absence of nerve root compression.
The ventral or anterior sacrococcygeal ligament is an extension of the anterior longitudinal ligament (ALL) that runs down along the spine on the anterior sides of the bodies of the vertebrae. It consists of a few irregular fibers that attach to the anterior sides of the sacrum and coccyx and blend with the periosteum. [1]
A whiplash injury may be the result of impulsive retracting of the spine, mainly the ligament: anterior longitudinal ligament which is stretched or tears, as the head snaps forward and then back again causing a whiplash injury. [18] A whiplash injury from an automobile accident is called a cervical acceleration–deceleration injury.
The anterior sacrococcygeal ligament or ventral sacrococcygeal ligament consists of ... ligament forms the continuation of the anterior longitudinal ligament [3] [4 ...
The cruciate ligament of the atlas consists of the transverse ligament of the atlas, a superior longitudinal band, and an inferior longitudinal band. [1] [2] The superior longitudinal band connects the transverse ligament to the anterior side of the foramen magnum (near the basilar part) in the occipital bone of the skull.
