What is the atlanto dens interval?

What is the atlanto dens interval?

The atlantodental interval (ADI), as the name suggests, is the horizontal distance between the anterior arch of the atlas and the dens of the axis, used in the diagnosis of atlanto-occipital dissociation injuries and injuries of the atlas and axis.

What is C1 C2 subluxation?

(C1–C2 Subluxation) Atlantoaxial subluxation is misalignment of the 1st and 2nd cervical vertebrae, which may occur only with neck flexion. (See also Evaluation of Neck and Back Pain.

On which radiographic view is the Atlantodental interval Adi measured?

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 TDI and ADI?

The acceptable daily intake (ADI) is used widely to describe “safe” levels of intake; other terms that are used are the reference dose (RfD) and tolerable intakes that are expressed on either a daily (TDI or tolerable daily intake) or weekly basis.

• pain in the jaw.
• neck pain or a stiff neck.

What is mg/kg bw day?

What is Spinolaminar line?

spinolaminar line: posterior margin of the spinal canal. posterior spinous line: tips of the spinous processes.

What happens when atlas is out of alignment?

The atlas shifts out of place ever so slightly and presses upon, stretches, or otherwise impinges on the nerves of the brain stem. This causes interference in the nerve flow between the brain and body and most commonly affects the muscles along the spine, typically tightening the muscles along one side.
