The atlanto-axial joint, consisting of the atlas (C1) and axis (C2), plays a vital role in enabling cervical spine rotation but lacks the bony stability found in the lower cervical vertebrae.

2023年10月30日 · 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.

The atlanto-axial joint is a joint between the atlas bone and the axis bone, which are the first and second cervical vertebrae. It is a pivot joint that provides 40 to 70% of axial rotation of the head.

2024年8月20日 · The atlanto-axial articulation is a complex of three synovial joints, which join the atlas (C1) to the axis (C2). The atlanto-axial joint allows 10-15 o of flexion/extension, 30 o of axial rotation and only minimal lateral flexion. There are a number of congenital anomalies which can affect the atlas, axis and the joint between the two:

2023年8月28日 · The atlantoaxial joint is a unique joint with multiple distinct structural aspects contributing to its crucial function for cervical stability and mobilization. It consists of three distinct synovial joints: one medial joint and two lateral atlantoaxial joints.

The atlantoaxial joint is a pivot synovial joint between the atlas and axis vertebrae. The vertebrae communicate with each other at three separate synovial joints; two lateral plane synovial joints and one median pivot joint.

2012年12月6日 · The atlas and axis form the atlanto-axial joint, which allows head rotation. If you shake your head as if to say "no," that is head rotation. The atlanto-axial joint is a compound synovial joint.

2023年6月12日 · The atlantoaxial joint is the most mobile joint, with several critical neurovascular structures traversing through it. The atlantoaxial segment consists of the atlas (C1) and axis (C2) and forms a complex transitional structure bridging the occiput and cervical spine.

2024年9月26日 · The atlantoaxial joint is a complex joint between atlas (c1) and axis (C2) which helps with axial rotation allowing our head to turn left and right and is supported by a complex set of ligaments and muscles.

2023年3月31日 · The atlantoaxial joint is a specific joint with multiple distinct structural parts donating to its crucial function for cervical stability & mobilization. It consists of 3 distinct, synovial joints: one medial joint & two lateral atlantoaxial joints.
