Flashcards in Chapter 1 Deck (13)
What are the basic directions the ilium can misalign?
Anterior, posterior, medial, and lateral
Where does the misalignment occur?
What is the most important change the AS ilium undergoes?
Decrease innominant measurement
What are the obturator changes occuring with AS and PI?
AS= decrease length diagonally
PI= increase length diagonally
Lordosis changes for AS and PI? Femur head changes?
AS= hypolordosis, raises femur head
PI= hyperlordosis, lowers femur head
Will and AS always be found on the side of the high femur head?
No, it depends on the degree of subluxation as well as anatomical and physiological abnormalities, etc
What is one of the most reliable signs of ilium being subluxated?
Fluid in the joint space
Describe where edema will be found with AS and PI
AS= posterior inferior and anterior superior margin of joint
PI= posterior superior and anterior inferior margin of joint
What causes the joint edema in AS and PI?
As the SI joint subluxates, it leaves openings in the joint space and fluid accumulates
Describe the relationship of sacrum to AS and PI ilum
AS= sacrum is posterior
PI= sacrum is anterior
How do you determine subluxation/compensation?
Subluxation is found on the side of the lowest lumbar body rotation (usually L5)
Errors in instrumentation?
1. Using uneven pressure
2. Not enough pressure, causing air leaks
3. Not having the thermocouples fit the cervical spine resulting in air leaks
4. Not repeating the glide often enough when a break is suspected
5. Not keeping a constant glide speed
6. Marking skin lesions as subluxations
7. Not marking the peak
8. Marking the recession
9. Stopping the glide when a reading is found
10. Not keeping the scope centered on the spine or following the scoliosis curves
