16
Q

What is the recommended torque for halo pins in adults and in children?

A

Adults: 8 inch pounds
Children: 4-6 inch pounds

17
Q

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

A

MRI compatible

18
Q

Halo pins are tightened in what fashion?

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/her eyes open or closed?

A

closed

20
Q

what tool would you use to apply halo pins?

A

Torque screwdriver

21
Q

The pins on a halo should be re-tightened at what time interval after initial appliation?

A

48 hours

22
Q

An inflamed pin-site, noise or movement are indications of what?

A

Loose pin

23
Q

What are the advantages of using a breakaway torque wrench?

A

Wrench brakes off at set amount of torque. Smaller in size for getting into cramped areas

24
Q

What two nerves could be compromised with incorrect positioning of the anterior pins?

A

Supraorbital and Supratrochlear nerves

25
Q

What is Risser sign?

A

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

26
Q

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

A

The upper pressure point for high scoliotic curves or kyphosis – not a distractive force

27
Q

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

A

So that it is x-ray transparent

28
Q

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

A

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

29
Q

Name and describe two other types of pads?

A

*Shoulder ring
*Lumbar (kidney shape pad)
*Anterior derotation

30
Q

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

A

Two fingers (1”) below the chin

31
Q

How long does a patient normally wear a scoliosis orthosis?

A

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

32
Q

What is the most common type of scoliosis?

A

Idiopathic, occurs most often in girls

33
Q

Do you treat functional and structural scoliosis the same?

A

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

34
Q

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

A

Current thinking is 25-40 degrees and progressive

35
Q

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

A

T6-T8

36
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. Compensatory curves accommodates the primary to center the head over the pelvis
