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.

The cervical spine consists of seven distinct vertebrae, two of which are given unique names: The first cervical vertebrae (C1) is known as the atlas. The second cervical vertebrae (C2) is known as the axis. Cervical spine. There are two different joints present throughout the vertebral column: The disc joint (determines how much vertebral

The atlas is the first and top cervical vertebrae (C1), holding the head (occiput) and thus forms the atlanto-occipital joint (A-O). The second cervical vertebrae, is the axis, or C2. The atlas (C1) pivots on the axis of the dens, making it a unique type of joint compared to the other vertebral joints. It's called the atlantoaxial joint or A

The atlantoaxial joint is the most mobile joint, with several critical neurovascular structures traversing through it.[1]The atlantoaxial segment consists of the atlas (C1) and axis (C2) and forms a complex transitional structure bridging the occiput and cervical spine. The functional result of the joint is two-fold: (1) providing support for the occiput and (2) providing the greatest range of

https://www.kenhub.com/en/library/anatomy/atlantoaxial-joint
The atlantoaxial joint is a complex joint between the atlas (C1) and the axis (C2). It is composed of three synovial joints; one median atlantoaxial joint and two lateral atlantoaxial joints . The median atlantoaxial joint is formed between the dens of axis and an osteoligamentous ring of the atlas anteriorly and transverse ligament posteriorly.

Manipulation of the spine (MTS)can also be defined as a form of manual therapy that is used in an effort to reduce pain and improve range of motion [3]. Cervico-thoracic spine joint manipulation or mobilization are a physiotherapy or chiropractic intervention that can be used for neck, back or shoulder pain. [4]

The atlantoaxial motion segment, which is responsible for half of the rotational motion in the cervical spine, is a complex junction of the first (C1) and second (C2) cervical vertebrae. Destabilization of this joint is multifactorial and can lead to pathologic motion with neurologic sequelae. Posterior spinal fixation of the C1-C2 articulation in the presence

The C1 and C2 vertebrae are the first two vertebrae at the top of the cervical spine. Together they form the atlantoaxial joint, which is a pivot joint. The C1 sits atop and rotates around C2 below. More of the head's rotational range of motion comes from C1-C2 than any other cervical joint. 1 Mead LB, Millhouse PW, Krystal J, Vaccaro AR.

https://www.ncbi.nlm.nih.gov/books/NBK563271/
The atlantoaxial joint is a type of synovial joint that is classified as a uniaxial pivot joint. This joint resides in the upper part of the neck between the first and second cervical vertebrae, also known as the atlas and axis, respectively. The pivot joint classification means that it allows for rotation only and is formed by a central pivoting, bony structure that rotates around

C1-C2 screw fixation; C0-C2 fusion (Goel and Harms Technique) Occipital-cervical Fusion (Skull Base to C2) C1-C2 screw fixation is likely the most common procedure we see. This involves placing a screw across the C1-C2 joint and is involved in atlantoaxial instability (AAI). The main problems have been: Lack of fusion of the C1-C2 joint.

The issue with this test is that it tends to also include motion at the C2-3 joint, resulting in at least 45 degrees of rotation in a normal joint bilaterally. To truly assess AA rotation, maximally sidebend the cervical spine ipsilaterally and rotate contralaterally, while maintaining chin tuck (if chin tuck is lost, isolation to C1-2 is lost

https://centenoschultz.com/atlantoaxial-subluxation/
Atlantoaxial subluxation is when there is a misalignment of the C1/2 joint . This can involve the C1 bone, the C2 bone, or both. Injury to the upper cervical ligaments can lead to atlantoaxial subluxation. Ligaments are thick pieces of connective tissue that connect one bone to another. The AA joint is the most mobile in the body.

Traction refers to stretching and/or realigning the spine to relieve direct nerve pressure and stress on the vertebral levels. Traction of C1-C2 may help decrease compression of the C2 nerve. Traction of cervical vertebrae is a commonly recommended procedure for both adults and children.

The most common technique for C1-2 fusion is based on posterior approaches. Anterior approaches are beneficial in using the Smith Robinson approach to the anterior cervical spine. Blood loss is minimized and complications associated with the posterior approach to the cervical spine are removed. The most common approach to C1-C2 fixation has

C1-C2 fusion means using screws, rods, or bone to make sure that the C1-C2 joint doesn't move. While the most common reason this rare procedure was performed used to be because of an upper neck fracture or severe ligament rupture, these days more of these procedures are performed in patients with ligament laxity leading to upper cervical
