Positioning HW7 test
| Question | Answer |
|---|---|
| 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 |
