Anterior Atlantoaxial Ligament

Anterior atlantoaxial ligament (shown in red) in relation to the atlas and axis vertebrae.

The Anterior Atlantoaxial Ligament is a crucial anatomical structure in the human body, specifically within the vertebral column. It is one of the ligaments that contribute to the stability of the atlantoaxial joint, which is the joint between the first and second cervical vertebrae, the atlas (C1) and axis (C2) respectively.

Anatomy[edit | edit source]

The Anterior Atlantoaxial Ligament extends from the anterior arch of the atlas to the body of the axis. It is broader and stronger than the Posterior atlantoaxial ligament, which is located on the opposite side of the vertebrae. The ligament is covered by the longus colli muscle and the rectus capitis anterior muscle.

Function[edit | edit source]

The primary function of the Anterior Atlantoaxial Ligament is to provide stability to the atlantoaxial joint. It restricts the posterior sliding of the atlas (C1) on the axis (C2), and limits the extension of the atlantoaxial joint.

Clinical Significance[edit | edit source]

Damage or injury to the Anterior Atlantoaxial Ligament can lead to instability of the atlantoaxial joint, which can result in serious conditions such as atlantoaxial instability or atlantoaxial subluxation. These conditions can cause neurological symptoms due to compression of the spinal cord.
