A

adults - 8 in/lbs

children 4-6 in/lbs

17
Q

what is the reasoning behind using non-ferrous components in halo systems?

A

MRI compatible

18
Q

A

2 in/lbs alternating opposing diagonal forces until 6-8 in/lbs is reached.

19
Q

During anterior pin placement, should the patient have his eyes closed or open?

A

closed

20
Q

What tool would you use to apply halo pins

A

torque screwdriver

21
Q

A

24-48 hours

22
Q

An inflamed pin site, pain at the pin site, noise or movement are indications of what?

A

Loose pin

23
Q

Your pain comes into your office with a loose pin. You try to re-tighten and no resistance is met. Your next step would be:

A

Call the dr.

24
Q

What are the advantages of using breakaway torque wrench?

A

wrench breaks off at set amount of toque. smaller in size for getting into cramped areas

25
Q

what 2 nerves could be compromised with incorrect positioning of the anterior pins?

A

supraorbital & supratrochlear nerves

26
Q

What is Risser Sign?

A

Method of determining bone maturity, using x-ray, reading the iliac epiphysis, graded 0-5

27
Q

what is the purpose of the neck ring on a Milwaukee?

A

the upper pressure point for high scoliosis curves or kyphosis - not a distractive force

28
Q

Why is the anterior bar of a milwaukee made of aluminum?

A

so that it is x-ray transparent

29
Q

What is the proper placement for a thoracic pad on a CTLSO?

A

2 ribs inferior to the apex of the curve, pad is “L” shaped

30
Q

Name and describe 2 other types of pads?

A

shoulder ring, lumbar (kidney shaped pad), anterior derotation

31
Q

What is proper clearance of the throat mold on a CTLSO?

A

32
Q

how long does a patient normally wear a scoliosis orthosis?

A

until skeletal maturity, then patient is “weaned” off the brace

Q

What is the most common type of scoliosis?

A

idiopathic, occurs most often in girls

34
Q

Do you treat functional & structural scoliosis the same?

A

No, functional curves are fit with corrective devices, structural curves are usually treated with an accommodative device

35
Q

What are the upper and lower limits, in degrees for treatment of scoliosis orthotically?

A

Current thinking is 25-40 & progressive

36
Q

At what spinal level would you consider using a CTLSO rather than a TLSO for scoliosis?

A

T6 - T8

37
Q

How do you determine which is the primary curve and which is compensatory?

A

the primary curve is the more structural, curve will always have rotation.
