A

roll toward the affected side

19
Q

This device is used to measure the proper degree of abduction when examining a patient for congenital hip dislocation.

A

protractor

20
Q

The upright pelvis study is used to best demonstrate –1–.

A

acetabular joint space narrowing

21
Q

The Lauenstein Method for lateral projections of the hip will utilize a CR that is –1–.

A

perpendicular to femoral neck

22
Q

The Hickey Method for lateral projections of the hip will utilize a CR that is –1–.

A

20-25 degrees cephalic

23
Q

When performing an upright leg length study on a long cassette, what anatomy should be demonstrated?

A

The hip joint to the ankle joint

24
Q

In reference to #23 (When performing an upright leg length study on a long cassette, what anatomy should be demonstrated?), what are 2 instructions that must be given to the patient prior to the exposure?

A
  1. Remove shoes

2. Stand with equal weight on both feet

25
Q

When performing a unilateral “frogleg” Modified Cleaves Method, the CR should be directed to the –1–.

A

femoral neck

26
Q

When performing a pelvis exam, list 2 anatomic structures that should be demonstrated to show proper patient positioning has occurred.

A
  1. Greater Trochanter are pulled into profile

2. The femoral necks should be parallel to IR, not superimposed on itself

27
Q

The –1– Method could be performed if a patient has bilateral hip injuries that prevent either a “frog” lateral or cross-table lateral/Danelius Miller Method (but, pt. can’t elevate unaffected leg).

A

Clements-Nakayamma Method

28
Q

When performing either a Lauenstein or Hickey Method the femur should be placed –1– to the IR/ table.

A

parallel

29
Q

The CR should be –1– to the femoral neck for the cross table lateral hip exam.

A

perpendicular

30
Q

The IR should be –1– to the femoral neck for the cross table lateral hip exam.

A

parallel

31
Q

List 2 things that could be done when performing the cross table lateral hip exam that could greatly improve the image quality of the radiograph.

A
  1. Use a grid

2. Use a compensating filter

32
Q

What is the degree of leg abduction/flexion for the Modified Cleaves Method?

A

35 degrees (25-45 degrees)

33
Q

What should be done to the unaffected leg when performing a lateral distal femur?

A

It should be draped over the affected leg. Not superimposed.

34
Q

How many degrees should the knee be flexed when performing a lateral distal femur?

A

45 degrees

35
Q

What are the 3 structures that form the acetabulum along with the fractional division and location of each?

A

Ilium 2/5 Superior
Ischium 2/5 Posterior
Pubis 1/5 Anterior

36
Q

The flat “wing-like” portion of the ilium is called the –1–.

A

ala

37
Q

What joint classification (by movement) is the pubis symphysis?

A

amphiarthrotic

38
Q

What anatomy must be included on a pelvis radiograph?

A

The illiac crest to the ischial tuberosities. The complete hip joint including the greater trochanter. The proximal third of the femur with the lesser trochanter.

39
Q

Name the 3 ways to localize the hip joint:

A
  1. Bisect the crease of the leg and the hip
  2. Go 2 inches medially from greater trochanter
  3. Bisect pubic symphysis and ASIS and then go down 2 inches at a right angle
40
Q

Why will the femoral condyles NOT be completely superimposed when performing the lateral femur?

A

The medial condyle hangs lower than the lateral one.

41
Q

How much should the knee be flexed for a lateral patella?

A

5-10 degrees

42
Q

Name the 2 reasons we do a chest in the upright position if possible?

A
  1. Puts the diaphragm in its lowest natural position

2. Prevent engorgement of pulmonary vessels

43
Q

Which lateral/axiolateral hip Method will demonstrate the neck without superimposition, the Lausenstein or the Hickey?

A

Hickey
