What is Atlantoaxial degeneration?
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 is the Atlantodental joint?
Introduction. The atlantoaxial joint is a type of synovial joint that is classified as a biaxial, 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.
What type of joint is the Atlantooccipital joint?
condyloid synovial joints
The atlanto-occipital articulation (also known as the C0-C1 joint/articulation) is comprised of a pair of condyloid synovial joints that connect the occipital bone (C0) to the first cervical vertebra (atlas/C1).
Is arthritis the same as arthrosis?
Arthritis is an inflammatory condition involving one or more joints throughout the body that causes pain, swelling and warmth in the affected areas. Arthrosis is a non-inflammatory degenerative condition associated with aging.
Where is atlantoaxial joint?
cervical spine
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.
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 movement does the atlantoaxial joint allow?
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 the atlanto-axial joint?
Is arthrosis autoimmune?
Rheumatoid arthritis is an autoimmune disease. Normally, your immune system helps protect your body from infection and disease. In rheumatoid arthritis, your immune system attacks healthy tissue in your joints. It can also cause medical problems with your heart, lungs, nerves, eyes and skin.
Is atlanto-axial pannus a possible complication of rheumatoid arthritis?
Pannus formation in the atlanto-axial joint is a well-recognized complication of rheumatoid arthritis (RA). Occasionally, atlanto-axial pannus is reported when patients without a history of RA undergo magnetic resonance imaging (MRI) of the cervical spine. We sought to further characterize these patients.
What is atlantoaxial osteoarthritis?
Atlantoaxial Osteoarthritis is a metabolically active, dynamic process that involves all joint tissues such as cartilage, synovium/capsule, ligaments and muscles. It refers to a clinical syndrome of joint pain accompanied by varying degrees of functional limitation and reduced quality of life . (Level of evidence 5, Level of evidence 1B)
What is the lateral atlantoaxial joint complex?
The lateral atlantoaxial joints are bilateral joints formed between the lateral masses of the atlas and axis. These joints are classified as gliding, or plane joints. The primary movement of the atlantoaxial joint complex is rotation.
What is the differential diagnosis of atlantoaxial joint osteoarthritis?
It is also important that atlantoaxial joint osteoarthritis should be considered in the differential diagnosis in elderly patients examined for neck pain with or without progressive quadriparesis. The identification of a periodontoid ligamentous degenerative mass suggests the presence of instability of the atlantoaxial joint.
