Alar ligaments

Organization and role

They contribute particularly to limiting rotation and lateral bending. Their shape and signal vary; an isolated image does not establish instability.

Clinical relevance and investigation

After significant trauma, suspected ligament injury requires appropriate medical assessment. A manual test does not replace imaging when an unstable lesion is suspected.

Points to consider

Stability depends on bones, capsules, ligaments, discs and muscles working together. Naming a joint or ligament does not establish injury. After trauma, their integrity must be considered before therapeutic mobilization.

Role of TAGMED care

At TAGMED, assessment aims to understand symptoms, history and functional limitations. Manual care and osteopathy, motorized spinal decompression, laser and shockwave have different indications. The term described in this entry is not enough to select any of these modalities. Their relevance, limitations and possible contraindications should be discussed in relation to diagnosis and individual goals.

Related concepts and distinctions

• Transverse ligament of the atlas — Ligament connecting the atlas lateral masses behind the dens and helping hold the dens against the anterior arch of C1.
• Nuchal ligament — Posterior midline fibrous structure of the neck, functionally continuous with the supraspinous ligament and providing attachment for several neck muscles.
• Intertransverse ligaments — Ligaments connecting transverse processes of adjacent vertebrae and contributing to the restraint of some lateral movements.
