Subluxation vs. Compensation

Question 1

What might offset femur height other than subluxation?

Answer 1

• anatomically short leg
• knee/ankle injury
• previous fracture

Question 2

If there is a wedged disc below a level vertebra, is it most likely to be a subluxation or compensation?

Answer 2

compensation

Question 3

If there is a wedged disc above a level vertebra, is it most likely to be a subluxation or compensation?

Answer 3

Subluxation

Question 4

how often is atlas compensatory?

Answer 4

82%

Question 5

Why are compensatory vertebra moveable?

Answer 5

Because their nuclei are intact

Question 6

How will occiput compensate for an anatomic deficient leg?

Answer 6

Condyle will be elevated on side of short leg

Question 7

What do taut and tender fibers typically indicate?

Answer 7

Possible compensation

Question 8

What do lax fibers typically indicate?

Answer 8

Possible Subluxation

Question 9

Why is compensation so prevalent in the cervical spine?

Answer 9

• Because cervical spine adapts to subluxations outside the cervical area
• tend to occur in higher cervical segments
• atlas more than occiput

Question 10

What direction does compensation occur in?

Answer 10

• Anteriorly, for a posterior subluxation

- to maintain body balance

Question 11

Can compensation become subluxation?

Answer 11

• YES

- a simple misalignment can become a subluxation dependin on the type of force that’s put into the body

Question 12

How do most cervical subluxation occur?

Answer 12

• head being driven forward
• mechanically–>when hyperflexed, verteral bodies close at the anterior margin
• the forces transmitted through segments drives the vertebrae post./inf.

Question 13

How could atlas be responsible for subluxation below?

Answer 13

• by causing cord pressure, affecting Gamma efferent motor fibers
• Causing paravertebral muscle contraction via stretch mechanism
• the atlas would have to be corrected to clear the cord pressure, allowing::: muscles to relax, correction of other subluxations

Question 14

What causes subluxation in upper cervical and sacroiliac regions?

Answer 14

• damage to interarticular ligaments due to osseous misalignment
• causing the casular ligament to swell: Producing nerve pressure
• Inflammation reaction occurs:: resulting in altered metabolic rate & heat of a nerve, Head detectible on skin surface

Question 15

WHy can a vertebra not subluxate anteriorly?

Answer 15

Because of the superior articular facets

Question 16

How much force is required to subluxate?

Answer 16

Minor force:

• Sneeze
• Stepping off the curb the wrong way

Question 17

Where does subluxation occur in the vertebrae?

Answer 17

DISC!!!

Question 18

What allows for inferiority of vertebra?

Answer 18

• As the vertebra slips backward, it pushes the nucleus forwards
• allowing posterior part of vertebra to drop inferiorly

Question 19

How are the bodies of C5-L5 rotated when the sacrum has gone posterior?

Answer 19

They rotate to the side of the posterior rotated sacrum

Question 20

WHen the ilium subluxates, what causes the ilium to stay in that direction?

Answer 20

Edema

Question 21

What are the 3 components of a subluxation?

Answer 21

• Fixation
• Edema
• Nerve impingement: causing physiological and pathological conditions

Question 22

Each subluxation results in________

Answer 22

compensation
