Chapter 6 Flashcards
What constitutes vertebral misalignment?
Posteriority
How is posteriority expressed?
In terms in relationship between 2 vertebral bodies
Where does subluxation occur?
At the disc
Why can a vertebra not subluxate anteriorward? Why do people think it has? Exceptions?
Because of the superior articular facets
Because the one above has gone posterior making it appear anterior
Ligament avulsions or fractures
Wedging- where does the nucleus go?
Laterally to the side of the open wedge
Why contact mammillary process on rotation listing?
To close the wedge
Why can’t the vertebral body be lifted laterally on to the disc?
Because of the nucleus
Why can L5 be lifted laterally on to the disc?
Because is it possible to stabilize the sacrum and pelvis making it a firm foundation and can be lifted from the low side to the high side
How do you determine body rotation (3)?
Spinous position, pedicle size, changes in width of the inferior articular processes
How do you determine wedging (3)?
Vertebral endplates, superior junction of the transverse processes to the body, superior and inferior pedicle borders
When evaluating rotation of L5 what else must you look at?
Sacrum
When evaluating L5 what do you compare it to?
Sacral base line at the sacral grooves
