What is normal Atlantodental interval?
The atlantodental interval (ADI) is a measurement used to evaluate the atlanto-axial relationship. This distance, described by Hinck et al,6 is conventionally held to be normal when it is less than 3 mm in men and 2.5 mm in women.
Where is the Atlantodental interval?
The atlantodental interval (ADI) is measured between the posterior aspect of the anterior atlas ring and the anterior aspect of the odontoid process. The ADI is often constant in distance during movement of the head and generally does not exceed 3 mm for adults and 5 mm for children.
What is the normal dimension of the Atlantodental interval in adults?
The normal adult anterior atlantodental distance (ADI) values have been reported as ≤3mm in males and ≤2.5mm in females6. It has been stated that values greater than these values should be evaluated pathologically and patients should be strictly monitored and treated.
What is Atlantodental arthritis?
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.
How is osteoarthritis of the spine treated?
Non-surgical treatments are the mainstay of osteoarthritis management, including spinal arthritis known as spondylosis. Anti-inflammatory medications, most commonly ibuprofen or other non-steroidal anti-inflammatory medications (NSAID), are used to reduce swelling and to relieve pain.
What is the Atlantodental articulation?
The atlanto-axial joint is a joint in the upper part of the neck between the atlas bone and the axis bone, which are the first and second cervical vertebrae. It is a pivot joint. Atlanto-axial joint. Anterior atlantooccipital membrane and atlantoaxial ligament.
Where is the lateral atlantoaxial joint?
It is classified as a pivot joint. The lateral atlantoaxial joints are bilateral joints formed between the lateral masses of the atlas and axis….Atlantoaxial joint.

What is Atlantodental interspace?
The ADI is measured from the inferior border of the anterior tubercle of the C1 arch to the Odontoid process (Dens) of C2. The normal width is 1–5 mm for children & 1–3 mm (maximum) in adults. This space may increase in old age as a response to degeneration of the atlantodental joint complex.
