Q

When the atlas and axis rotate in opposite directions.

A

Variable

18
Q

In a variable, which vertebra should the chiropractor adjust?

A

Atlas

19
Q

Which should Atlas always be considered over Axis to adjust in a variable?

A

Adjust axis could potentially increase the rotational component of the atlas listing putting more torsion on the cord area

20
Q

Occurs when the atlas listing shows no rotation and/or the axis listing is Entire Segment Right or Entire Segment Left.

A

Non-applicable

21
Q

4 films required for Upper Cervical analysis

A
  • Lateral
  • Nasium
  • Base Posterior
  • A-P Open Mouth
22
Q

Alternate names for the 4 films required for Upper Cervical analysis

A
  • Longitudinal (Lateral)
  • Horizontal (Nasium)
  • Vertical (Base Posterior)
  • Vertico-horizontal (A-P Open Mouth)
23
Q

Primary and secondary findings on a Lateral x-ray

A 
Primary = Obtain second letter of the atlas listing (AS or AI)
Secondary = Evaluate the C1/C2 relationship, check for any cervical anomalies, and evaluate the cervical curve (lordotic typically)
24
Q

3 lines associated with the Lateral Film

A

1) Occipital Condyle Line (OCL)
2) Atlas Plane Line (APL)
3) Listing Line (LL)

25
Q

How to draw the OCL

A

Occipital Condyle Line
-Place dots at the anterior and the posterior aspect of the occipital condyle at the level of the floor of the skull. Connect the dots to make the line

26
Q

How to draw the APL

A

Atlas Plane Line
-Place a dot at the center of the anterior tubercle as close to the anterior arch as possible and one at the center of the narrowest portion of the posterior arch. The APL is made by connecting these dots.

27
Q

How to draw the LL

A

Listing Line
-Place your parallel on the OCL and roll down until you get to the dot on the posterior arch. The LL is constructed by drawing a line through the dots

28
Q

T/F The OCL and LL are parallel to one another

A

True

29
Q

How many degrees between the APL and LL is considered normal

A

APL is above LL by 4 degrees

30
Q

Any measurement of the APL and LL greater than 4 degrees gives the listing __ which anything below 4 degrees indicates the listing of __

A

> 4 degrees = AS

<4 degrees = AI

31
Q

The APL is above the LL by 7 degrees. What is the correct listing?

A

AS3

32
Q

The APL and the LL are on the same plane (0 degrees) What is the correct listing?

A

AI4

33
Q

The LL is above the APL by 9 degrees. What is the correct listing?

A

AI5

34
Q

What APL is above the LL by 2 degrees. What is the correct listing?

A

AI2

35
Q

Primary and secondary findings on a Nasium film

A 
Primary = Determine 3rd letter of the Atlas listing(Atlas Laterality)
Secondary = determine if there is a possible condyle malformation
36
Q

4 lines used for Nasium film

A

1) Ocular Orbit Line (OOL)
2) Superior Basic Line (SBL)
3) Inferior Basic Line (IBL)
4) Vertical Median Line (VML)

37
Q

How to drawl the OOL

A

Ocular Orbit Line
1) Place dots on as many sets of like points on the ocular orbit as possible. Draw the OOL through a set of like-points that has atleast one more set of points parallel to them

38
Q

How to draw the SBL

A

Superior Basic Line
-Place dots on the medial-inferior tips of the occipital condyles on both sides. Place the parallel on the OOL and roll down until you come to the first condyle tip. Draw a line through it.

39
Q

How to draw the IBL

A

Inferior Basic Line
-Place dots on the lateral-inferior tips of the atlas lateral mass on both sides. The IBL is constructed by connecting these dots.

40
Q

What must be drawn prior to drawing the VML?

A

Need to construct the “+” signs
