Q

What is the physiological cause of femur heigh deficiency

A

Misalignments of the pelvis

17
Q

For every ____ mm of PI or EX Correction the femur head will be raised ____ mm

A

5 & 2

18
Q

What happens to the femur head upon correction of an AS or IN?

A

Femur head will lower

19
Q

What does a AS or IN subluxation do to the leg length?

A

Draws the leg long

20
Q

What is the main reason for a heel lift?

A

If the patient is unable to retain his/her adjustments in the pelvis and spinal column

21
Q

Most people can adapt to a deficiency of up to ____ mm

A

6

22
Q

T or F

It is important to use a heel lift on a patient with 4 mm of deficiency

A

False

6

23
Q

T or F

When a heel lift is indicated it should be for the measured deficiency amount

A

False

For the full amount of actual deficiency AD

24
Q

T or F

The lumbar convexity goes to the side of the long leg

A

False

Short leg

25
Q

T or F

Raising the lower femur head would decrease the scoliosis

A

True

26
Q

If you saw a right convex scoliosis that was caused by a short leg, which leg would be short?

A

Right

27
Q

If you saw a left convex scoliosis and the AD on the left was 7 mm what side would you put the heel life and how many mm?

A

Left

7 mm

28
Q

T or F

Never prescribe a heel lift for a patient when the lumbar scoliosis is on the opposite side of the low femur head as this would tend to increase the scoliosis

A

True

29
Q

What are some contraindications with age and heel lifts

A

Pre-puberty - bones are still growing

After 45 - they don’t stretch very well.

30
Q

T or F

Drawing lines is only important for the vertebra that you need a listing for

A

True

31
Q

T or F

We compare to the bone above

A

False

32
Q

Where do you place dots on the vertebra to get your line?

A

Inferior portion of the pedicles

33
Q

Where do you write your listing?

A

The side of spinous rotation

34
Q

What if the spinous is not clear what else can you use to determine spinous rotation?

A

Pedicles
Sacrum
L4…

35
Q

In the cervical spine was do we use as a guide for drawing our lines?

A

Inferior vertebral endplate

36
Q

T or F

Uncinate processes are a reliable landmark for drawing lines in the cervical spine

A

False

37
Q

Pedicles on the side of spinous rotation may be referred to as:

A
