chapter 7 hip and pelvic girldle Flashcards
What four parts make up the Pelvis?
right and left hip bones, sacrum, coccyx
what makes up the Pelvic Girdle?
Right and left Hip Bones
Another name for Unilateral Frog- Leg
Modified Cleaves Method
Another name for Axiolateral inferosuperior
Danelius- Miller Method
Another name for Modified Axiolateral
Clemets- Nakayama Method
Another name for Posterior Oblique Acetabulum
Judet Method
Another name for Posterior Axial Oblique Acetabulum
Teufel Method
Plane of the inlet is located?
S1 to Symphysis Pubis
The angle of the pubic arch in a female is?
90 degrees obtuse,or grater than 90*
The angle of the pubic arch in a male is?
90 degrees acute
The Routine for a unilateral hip is?
AP and Frog-leg (only if no fracture is suspected)
The body of the femur lies?
15-20 degrees posterior to the femoral head
when positioning for the AP hip and AP pelvis you must rotate the leg inward ____ degrees
15-20 degrees to get a true AP where the femoral neck is parallel to the IR…thereby avoiding foreshortening of the neck.
The hip joint is classified as
synovial, diarthrodial (freely moving)
the bilateral modified Cleaves (frog leg) In this position the CR is?
3” distal from the ASIS. 1 inch above symphysis pubis.
Hip is classified as
synovial /diarthrodial /spheroidal
the female pelvis is
Wider, more shallow, more flared
Male shape of inlet
heart shaped, oval
Gender Differences of the Pelvis are
General shape
Angle of pubic arch
Shape of inlet
To minimize distortion of the femoral neck for an AP bilateral “frog-leg” projection, the lower limbs should be abducted?
45°
What type of CR angle is required for the AP axial “outlet” projection for a male patient?
20° to 35° cephalad
How much is the affected side rotated for the PA axial oblique projection (Teufel method)?
35° to 40
The greater sciatic notch is found on the
Ilium
The lesser sciatic notch is found on the
Ishium
The Greater Pelvis
also known as the false pelvis, found at L5 and S1 vertebrae, and is the flared portion of the pelvis which is formed by the wings/ala, a fetus rest here
The Lesser Pelvis
also known as the true pelvis, surrounded by bony structers forms the birth canal, defined by 2 ischial tuberosties and the coccyx
How is the cassette aligned for an axiolateral (Danelius-Miller method) projection?
Parallel to femoral neck
cetabulum, site of the fusing of _
the 3 hip bones together.Ilium,pubis, and ischium,..
the greater trochanters are located in the same horizontal line as the
symphysis pubis
femoral neck is located
1 to 2 inches medial & 3 to 4 inches distal to the ASIS.
internal rotation of the foot is to
bring out the greater trochanter and the femoral neck parallel to the film..
Which specific positioning error is present when the left obturator foramen is more open than the right side on an AP pelvis radiogragh?
right rotation / lateral rotation
Which CR angle is required for the “outlet” projection (Taylor Method) for a female?
30 to 45 degrees cephalad
How is the pelvis (body) positioned for a PA axial oblique (Teufel Method) projection?
PA 35 to 40 degree toward affected side
Where is the CR placed for an AP pelvis projection?
Midway between ASIS and symphysis pubis.2”inches inferior to level of ASIS.
What methods are modification of the frog-legs, where the patient is positioned normally except the pelvis is rotated toward the affected hip to position the femur against the table?
the hickey’s method
Which radiographic signs indicates that the proximal femurs are in position for a true AP projection?
Limited view of the lesser trochanter in profile
