Cruciate ligament of atlas
The cruciate ligament of the atlas (cruciform ligament) is a cross-shaped (thus the name) ligament in the neck forming part of the atlanto-axial joint. It consists of the transverse ligament of atlas, a superior longitudinal band, and an inferior longitudinal band.
The cruciate ligament of the atlas prevents abnormal movement of the atlanto-axial joint.
It may be torn, such as by fractures of the atlas bone.
Structure
The cruciate ligament of the
Variation
The inferior longitudinal band may be absent in some people; the rest of the ligament is invariably present.[3]
Gerber's ligament
In about half of individuals, an additional band - Gerber's ligament - arises at the junction of the transverse ligament and superior band, and is situated deep to the superior band.
Function
The cruciate ligament of the atlas prevents abnormal movements of the
Clinical significance
Any part of the cruciate ligament of the atlas may tear, which is a significant injury.[citation needed] This may be caused by fractures of the atlas bone.[3] Ligament tears may be imaged with radiography, a CT scan, or magnetic resonance imaging.[3]
Ossification
Very rarely, the cruciate ligament of the atlas may
Etymology
The terms "cruciform" and "cruciate" refer to the cross shape of the ligament.[1] Both terms are frequently used, although the term "cruciate" may be confusing due to confusion with the anterior cruciate ligament and the posterior cruciate ligament of the knee.[3]
