Axis (C2)

Axis

The axis is characterized by the dens (odontoid process), a tooth-like projection that extends superiorly from the body to articulate with the anterior arch of the atlas. This unique arrangement allows approximately 50% of cervical rotation.

الوظيفة

The second cervical vertebra that provides a pivot point for rotation of the head. The dens (odontoid process) projects superiorly and acts as the axis around which the atlas rotates.

الأهمية السريرية

Odontoid fractures are common cervical spine injuries, especially in elderly patients. Hangman's fracture involves bilateral pars interarticularis fractures of C2. Atlantoaxial instability occurs in rheumatoid arthritis and Down syndrome.
