(34 cards)
Which of the following will be shown “in profile” if the lower limbs are in correct position for an AP hip projection?
Greater trochanter
For the axiolateral projection of the hip (Danelius Miller method), unless contraindicated, how far internally is the leg rotated?
15-20 degrees
What is the CR angulation for an AP projection of the hip?
O
Perpendicular
Where is the bottom of the IR placed for an AP distal femur?
2 inches below the knee joint
The Settegast method, tangential projection of the patella should only be done once what has been ruled out?
Transverse fracture of patella
For the Hickey method of the hip, what is the degree of angulation of the tube?
20-25 degrees cephalad
Where is the top of the IR placed for an AP proximal femur?
ASIS
How is the central ray directed for the Lauenstein method of the hip?
Perpindicular to IR
How many degrees should both feet and lower limbs be internally rotated for an AP pelvis radiograph?
15-20 degrees
If your central ray is approximately 2 ½ inches distal on a line drawn perpendicular to the midpoint of a line drawn between ASIS and pubic symphysis, then what image would you be taking?
AP hip
For a PA projection of the patella, the heel must be laterally rotated. How many degrees does it need to be rotated?
5-10 degrees
For a follow-up examination for a postoperative fractured hip, which of the following would
be true?
true?
the entire prosthesis (orthopedic appliance) must be included in the image
How is the CR directed for a male patient when performing the Taylor method “outlet” projection of the anterior pelvic bones?
20-35 degrees cephalad
In an AP projection of the distal femur, the central ray is directed
Perpendicular
For the Hughston method of the patella, what is the angle that should be formed between the lower leg and the plane of the table?
50-60 degrees
Where is the top of the IR placed for an AP projection of the pelvis?
1 - 1 ½ inches above iliac crest
An open patello-femoral joint space should be seen on which of the following projections?
Lateral distal femur
How many degrees, and in which way should you have the patient rotate the lower limbs for an AP proximal femur?
10-15 internally
Where is the central ray directed for the Modified Cleaves projection (bilateral frog legs) of hips?
1 inch superior to the pubic symphysis.
How is the CR directed for a female patient when performing the Taylor method of the anterior pelvic bones?
10-25 degrees caudal
30 -45 degrees cephalad
The central ray for an AP pelvis should end up approximately
ASIS, and
inches) superior to the pubic symphysis.
2;2
How much of the femur should be visualized on an AP hip projection?
The proximal 1/3
Which of the following lateral hip views would be used if bilateral hip fractures were suspected?
Clements Nakayama
A Modified Axiolateral projection of the femoral neck (Clements Nakayama) is particularly useful:
- when the axiolateral is contraindicated
- for patients with bilateral hip fractures
- for patients with limited movement of the unaffected leg.
