Shouldn't be seen beyond the medial border of the femur or only a very small portion seen on the proximal femur
What portion of an orthopedic appliance should be demonstrated in the AP projection of the femur?
Any in its entirety?
True of false: gonadal shielding shouldn't be used because it may superimpose the femoral head
How should the pelvis be positioned to demonstrate the lateral proximal femur?
From true lateral, the pelvis should be rolled posteriorly about 10-15 degrees
How should the pelvis be positioned to demonstrate the lateral distal femur?
Concerning IR placement/collimated field location, to what level on the patient should the upper border of an IR or collimated field be placed when demonstrating the lateral proximal femur?
At the level of the ASIS
Concerning IR placement/collimated field location, to what level on the patient should the lower border of an IR or collimated field be placed when demonstrating the lateral distal femur?
2 inches beyond the knee
Concerning the placement of the unaffected (uppermost) limb, where should it be placed when demonstrating the lateral proximal femur?
Concerning the placement of the unaffected (uppermost) limb, where should it be placed when demonstrating the lateral distal femur?
In front of the affected limb
When demonstrating the lateral distal femur and including the knee, how many degrees should the knee be flexed?
About 45 degrees
Which term refers to the inferior tip of the patella?
Which part of the patella is the base?
Where on the femur is the lesser trochanter located?
Medial and posterior
Where is the fovea capitis located?
Which positioning maneuver should be performed to place the femoral neck in profile for the AP projection of the femur?
Rotate the lower limb medially 10-15 degrees
Which positioning maneuver should be performed to prevent the femoral neck from appearing foreshortened in the AP projection of the femur?
Rotate the lower limb medially 10 to 15 degrees
For the AP projection of the femur on typical adults, what should be done to ensure that both joints of the femur are demonstrated?
Perform a second exposure with another IR
For the lateral projection of the femur, how should the pelvis be positioned to demonstrate only the knee joint with the distal femoral shaft?
Posterior pelvic articulations
2 other names for the hip bone
Projects from the pubic bone
Hip socket formed by the fusion of three bones
Forms posterior aspect of pelvis
Found above the acetabulum
Part of the hip bone that forms the broad, curved portion called the ala
Articulates with the sacrum
Has a body and two rami
Winglike portion of ilium
The structure of the body that serves as a base for the trunk and as a girdle for the attachment of the lower limbs
4 bones that form the pelvis
2 hip bones
Which two prominent structures found on the ilium are frequently used as radiographic positioning reference points?
Iliac crest and ASIS
Anterior superior iliac spine
Which bone/portion of the hip bone consists of a body and two rami?
Which bone/portion of the hip bone extends inferiorly from the acetabulum and joins with the inferior ramus of the pubic bone
What bones of the hip bone form the obturator foramen?
By posterior union, the rami of the pubis and ischium
2 structures that form the posterior part of the pelvis
2 parts a pelvis is divided into by the brim of the pelvis
Greater (false) pelvis
Lesser (true) pelvis
The region between the inlet and the outlet of the true pelvis
Which gender (male or female) has a pelvis that is broader and shallower with a larger and more rounded outlet?
2 large processe located at the proximal end of the femur
2 areas of the proximal femur that are common sites for fractures in elderly patients
In a typical adult, in which direction (anterior or posterior) does the femoral neck project away from the long axis of the femur?
What are the major articulations of the pelvis by name and or abbreviation and their quantity?
1 pubic symphysis
2 hip joints
2 SI joints
2 palpable bony points of localization for the hip joint
Superior margin of pubic symphysis
How are the ASIS and superior margin of pubic symphysis used to locate the femoral neck?
Visualize line between ASIS and pubic symphysis
At midpoint extend a second line perpendicular and inferolaterally toward the femur
The long axis of the femoral neck lies parallel with the second line
True or false: the greater sciatic notch is located on the anterior border of ilium
True or false: in the seated position, the weight of the body rests on two ischial tuberosities
True or false: the highest point of the greater trochanter is in the same transverse plane as the midpoint of the hip joint.
How should the patient's lower limbs be positioned for the AP projection of the pelvis and proximal femora and why?
Rotated medially 15-20 degrees to place the femoral necks parallel with the IR
How is rotation of the pelvis detected in the AP projection of the pelvis and proximal femora?
The alae of the ilia are asymmetrical if the pelvis is rotated
Which plane of the body should be positioned on the midline of the table and grid for the AP projection of the pelvis and proximal femora?
