Atlantoaxial osteoarthritis is osteoarthritis of the joint between the two upper vertebrae in your neck (called the ‘atlas’ and the ‘axis’), which may cause cervicogenic headache.
What type of joint is the atlanto axial joint?
pivot joint
The median atlantoaxial joint is formed between the dens of axis and an osteoligamentous ring of the atlas anteriorly and transverse ligament posteriorly. It is classified as a pivot joint….Atlantoaxial joint.

Where is atlantoaxial joint located?
The C1 C2 spinal motion segment, also called the atlantoaxial joint, is located in the upper portion of the cervical spine. It consists of the C1 and C2 vertebrae, and the anatomical structures connecting them. This segment provides rotational motion, supports the head, and protects the spinal cord and nerve pathways.
Where is my AO joint?
Anatomy. Affectionately called the OA joint – the occiput (or back of the skull) sits like a foot ball on top of the 1st cervical vertebrae (the atlas).

What is an example of pivot joint?
The moving bone rotates within a ring that is formed from a second bone and adjoining ligament. The pivot joint is exemplified by the joint between the atlas and the axis (first and second cervical vertebrae), directly under the skull, which allows for turning of the head from side to side.
What is atlas and axis?
The atlas and axis vertebrae are the two most superior bones in the vertebral column, and they are part of the seven cervical vertebrae. The atlas is the top-most bone, sitting just below the skull; it is followed by the axis. Together, they support the skull, facilitate neck movement, and protect the spinal cord.
What is a pivot joint?
pivot joint, also called rotary joint, or trochoid joint, in vertebrate anatomy, a freely moveable joint (diarthrosis) that allows only rotary movement around a single axis. The moving bone rotates within a ring that is formed from a second bone and adjoining ligament.
Is the atlantoaxial joint a facet joint?

What is an AO joint?
An atlanto-occipital (AO) joint injection is an outpatient procedure for diagnosing and treating chronic upper neck pain and headache. What is the atlanto-occipital joint? Joints connect the vertebrae, the bones of your spine. These joints help guide your spine when you move.
What movement does the atlanto-occipital joint allow?
flexion-extension
The principal movement at the atlantooccipital joint is flexion-extension. This movement permits nodding of the head, as seen when indicating approval (the “yes” movement).
What is the best remedy for osteoarthritis?
