All Hip, Pelvis, Misc. Flashcards
In order to best demonstrate the ala it must be –1– to the IR.
Parallel
The proper degree of total abduction for the infant hip Andren Von Rosen Method should be –1–.
90 degrees
The internal oblique for acetabulum will demonstrate the –1– portion of the structure.
Anterior
This method will demonstrate the greater trochanter superimposed with the femoral neck.
Lauenstein
The Clements Nakayama Method uses a CR that is directed –1–.
15 degrees posteriorly
Name 2 reasons why the Chassard Lapine method is performed?
- Measuring horizontal or in pelvimetry (childbirth)
2. Relationship of femoral head to acetabulum
In order to demonstrate the left ala on a prone patient, state the necessary position.
RAO
The proper degree of abduction for a Modified Cleaves Method for a unilateral hip should be –1–.
45 degrees
The Hickey Method will utilize a CR angle of –1– degree –2–. Explain the importance of using this CR angle.
- 20-35 degrees
- cephalic
Without the angle the femoral neck and greater trochanter won’t be free of superimposition.
Why does the patient lean anteriorly for the Chassard-Lapine Method?
To get pelvic bones in contact with the table
What is the disadvantage to performing the Friedman Method?
Too difficult for patient to achieve position
Taylor Method angulations for men and women/why.
Men- 20-35 degrees cephalic
Women- 30-45 degrees cephalic
This is due to the differences in size and shape of men and women’s pelvis’/ childbearing.
The pelvic outlet radiographs will look similar to what spine radiograph?
AP axial lumbar (Lithotomy)
What are the criteria for the pelvic inlet radiographs?
Medially superimposed superior and inferior pubic rami
What position will the patient be placed in for the Lillienfeld method?
supine/ seated upright
Anterior as needed
Cassard-Lapine with restricted flexion
35 degrees cephalic
Staunig, Friedman
15 degrees posteriorly
Clements Nakayama
Perpendicular
Judet, PA anterior pelvic bones, Lauenstein, Lillienfeld
20-25 degrees cephalic
Hickey
40 degrees caudal
reverse Staunic/inlet
In order to demonstrate the illiac crest it should be placed –1– to the IR.
Perpendicular
When performing the Modified Cleaves Method for bilateral hips, the CR should be directed –1–.
1 inch superior to the pubic symphysis
The feet/legs should be inverted –1– degrees for the AP proximal femur study.
10-15 degrees
The feet/legs should be inverted –1– degrees for the AP pelvis
15-20 degrees
The “frog leg” lateral is acceptable when –1–.
there is no suspicion of fx and they are 1-17 yrs old
The routine cross table lateral hip method is the –1–.
Danelius Miller Method
What is the method used that is similar to the above named method in cases when bilateral injuries may occur?
Clements Nakaymama Modification
To demonstrate the right crest on a supine patient their position will be –1–
LPO
The CR should be directed to –1– for the Judet Method.
2 inches inferior to ASIS of affected side
This side down of the affected acetabulum will demonstrate –1–.
Posterior acetablulum fx if present
