Positioning HW7 test

QuestionAnswer
What structure of the pelvis articulates with the femur? Acetabulum
What bones of the pelvis compose the acetabulum? pubis, ischium, and ilium
On which bone is the ala located? ilium
what pelvic structure is NOT used as a positioning palpation point? ischial spine
What portion of the hip bone joins to form the obturator foramen? pubis and ischium only
what is the name of the border that extends on the hip bone from the posterior superior iliac spine to the ASIS? iliac crest
What is the name of the process that seperates the greater sciatic notch from the lesser sciatic notch on the hip bone? ischial spine
Which parts of the hip bones support the weight of the body when a person is sitting on a swing? ischial tuberosity
Where in the pelvis is the body of the pubis located? it forms part of the acetabulum
Where should the IR be centered for the AP projection of the pelvis? Modway between the ASIS and the pubic symphsis
Where on the midline of the patient should the central ray enter for the AP projection of the pelvis? 2inches (5cm) above the pubis symphsis
Which positioning maneuver should be performed to place the femoral necks parallel with the IR for an AP projection of the pelvis? rotate the lower limbs medially 15 to 20 degrees
How should the central ray be directed for the AP oblique projection(modified Cleaves method) to demonstrate bilateral hips? Perpendiculary
For which projection of the lower limb or pelvis should the hips be flexed and the femurs be abducted from the midline of the patient? AP oblique projection(modified Cleaves method) for femoral necks
Where on the midline of the patient should be central ray be directed for the AP oblique projection(modified Cleaves method)? 1inch (2.5cm) above the pubis symphsis
All of the following projections can be used to image a patient with a suspended intertrochanteric fracture except? lateral projection (lauenstein method) of the hip
For the Ap oblique projection (modified Cleaves method) what is the purpose of abducting the femurs the required nuber of degrees? to position the femoral necks parallel with the IR
WHich structue should be centered to the midline of the table when the AP oblique projection(modified Cleaves method) is adapted to demonstrate only one hip? ASIS
for which projection of an individual hip should the unaffected hip be flexed and the thigh be raised out of the way of the central ray? Axiolateral projection(Danelius-Miller method)
For which projection of the hip should the central ray be directed horizontally into the medial aspect of the affected thigh? Axiolateral projection(Danelius-Miller method)
What demontrates suspected fractures of the acetabulum the best? AP oblique projection (Judet method)
What postions would be used to demonstrate the posterior rim of the left acetabulum? 45 degree RPO
what specific portion of the acetabulum is demonstarted by the AP oblique projection external oblique position (Judet method?) Anterior rim
what best describes the pubic and ischial rami without foreshortening? Ap axial "outlet" projection (taylor method)
What is the proper central ray orientation for the AP axial projection (Taylor method) for female patients? 30 to 45 degrees cephalad
