Oblique Projection
Flexion / Extension Views
what dos oblique mean
from an angle
what is the oblique view useful for in the cervical
allow us to see the spinal foramen
what is the foramen
tunnel on each side of vertabrae through which nerve roots exit the spinal column.
in the lumbar spine, what is the oblique spine used for
to see the pars interarticularis
lies between the superior and inferior articular process bilaterally at each vertebral level
(scotty dog, see if it has broken neck)
where is the pars interarticularis
lies between the superior and inferior articular process bilaterally at each vertebral level
what is Atlantodental Interspace (ADI)
the measurement of the interspace between posterior aspect of anterior arch and dens
what is georges line
line transitioning through posterior vertical bodies in cervical spine
what is dens
a superior projecting bony element from the second cervical vertebrae (C2, or the axis)
what is posterior cervical line
c1 slippage due to odontoid fracture
what is the odontoid/dens
a projection from the second cervical vertebra (axis) on which the first (atlas) can pivot
what is atlantoaial alignment
lateral aspect of lateral c1 should align to c2
if not can prevent rotation and dislocation
what is Sagittal Dimension of the Cx Spinal Canal
measuring canal space from super imposition of laminae to posterior vertebral body
what isCervical Gravity Line
cating the center of the tip of the Odontoid Process, then dropping a line downward, perpendicular to the bottom of the film. This line should just touch the anterior body of C7.
