The apical ligament is separated anteriorly from the anterior atlanto-occipital membrane by a thin layer of fat and connective tissue. Posteriorly it is separated from the superior crus of the cruciform ligament by an intervening layer of connective tissue.

2020年11月16日 · The apical ligament is a small ligament that joins the apex (tip) of the dens of C2 to the anterior margin of the foramen magnum. It is the weak, fibrous remnant of the notochord and does not contribute significantly to stability.

The ligament of apex dentis (or apical odontoid ligament) is a ligament that spans between the second cervical vertebra in the neck and the skull.

APICAL LIGAMENT. The apical ligament is a thin, midline ligament running in the supradental recess between the basion of the foramen magnum and the atlantoaxial joint space or bony tip of the dens. It is separated anteriorly from the AAOM and posteriorly from the superior band of the cruciform ligament by fat and connective tissue.

The apical ligament of the dens is a fibrous cord-like ligament that supports the craniocervical joint by stabilizing the location of the dens by attachment to the occipital bone.

The authors conducted a study to describe the detailed anatomy of the apical ligament and to acknowledge or refute its historical description as a functionally significant contributor to craniocervical stability.

Results of the study support the concept that the apical ligament is best described as a vestigial structure that offers no significant added stability to the craniocervical junction. In fact, this ligament was absent in 20% of the specimens examined.

2000年5月1日 · In 20 adult human cadavers measurements of the apical ligament were obtained, and its detailed anatomy was observed. Ranges of motion were also assessed to discern the function of the apical...

2000年4月1日 · The authors conducted a study to describe the detailed anatomy of the apical ligament and to acknowledge or refute its historical description as a functionally significant contributor to craniocervical stability.

The apical ligament connects the odontoid with the foramen magnum. Function. Biomechanically, it provides additional stability against traction forces. Clinical Relevance. The apical ligament has very little neuroanatomical and biomechanical significance.
