Part 2
| Question | Answer |
|---|---|
| The________ are AP Oblique Projections (Posterior Oblique Positions) of the hip | Judet Views |
| The Judet Views are mostly for looking at the? | Acetabulum |
| The Internal/Obturator Oblique is performed | Affected side up |
| External/Iliac Oblique is performed | Affected side down |
| Internal/Obturator Oblique Procedure | The affected side is elevated 45°, CR is perpendicular, entering 2 inches inferior to the ASIS of the elevated side |
| External/Iliac Oblique Procedure | The affected side is down, meaning the Unaffected side is elevated 45° CR is perpendicular, entering at the pubic symphysis |
| An Internal/Obturator Oblique image is identified by | • the rounded open obturator foramen. • The elevated hip will be oblique, making it look thinner with many lines going through the ala of the ilium. |
| An External/Iliac Oblique image is identified by | •the “squished” obturator foramen •the wide flat ala of the ilium |
| For a Hip X-Ray, use | 10 x 12 IR running parallel to body part • Table/wall bucky or free detector with grid • 40 inch SID |
| Hip X-Ray Breathing Instructions | Suspended respiration |
| AP Hip Patient Position | Supine, Medially rotate the lower limb 15 – 20° |
| AP Hip Image Criteria | • Femoral neck is demonstrated without foreshortening • Femoral head, penetrated and seen through the acetabulum |
| Which X-Ray shows the greater trochanter in profile laterally with the Lesser trochanter superimposed by the femoral neck? | AP Hip |
| Lateral Hip Patient Position | • Flex the hip and knee of the affected side and draw the foot up as much as possible. • Abduct the thigh laterally approximately 45 degrees |
| Lateral Hip Image Criteria | • Femoral neck partially foreshortened • Greater trochanter superimposed with femoral neck |
| Which X-Ray is the lesser trochanter in profile medially? | Lateral Hip |
| What Position replaces lateral hip when the patients hip cannot be abducted? | Axiolateral Hip: Danelius-Miller |
| Axiolateral Hip: Danelius-Miller Patient Position | Elevate the unaffected leg on a suitable support so that the thigh is vertical rotate the affected lower limb 15 – 20° medially |
| Axiolateral Hip: Danelius-Miller CR Placement | • Horizontal beam, angled medially until perpendicular to the femoral neck • Enters the groin area midway between the anterior and posterior surfaces of the upper thigh |
| What CR placement would you use when performing a hip X-Ray? | Perpendicular through femoral neck |
| Axiolateral Inferosuperior Clements-Nakayama Patient Position | • 10 x 12 IR, vertical and crosswise, placed along the iliac crest, parallel to the femoral neck • IR tilted away from patient about 15-20° • Patient supine |
| Axiolateral Inferosuperior Clements-Nakayama CR Placement | • Horizontal beam, angled medially until perpendicular to the femoral neck • Also angled posteriorly 15-20° (matching tilt of IR) • Enters the groin area midway between the anterior and posterior surfaces of the upper thigh |
| Axiolateral Inferosuperior Clements-Nakayama is used instead of a Axiolateral Hip: Danelius-Miller when? | when neither hip can be abducted |
| Axiolateral Hip Image Criteria | • Greater trochanter superimposed with femoral shaft • Lesser trochanter in profile medially • Ischial tuberosity medial to the femoral head & neck |
| Which X-Ray demonstrates Femoral neck without foreshortening? | Axiolateral Hip |
| Which X-Ray shows the Greater Trochanters in profile? | AP Pelvis |
| The Hip Joint is? | Synovial, Ball and Socket, Freely Moveable |
| The Pubic Symphysis Joint is? | Cartilaginous, Symphysis, Slightly Moveable |
| The Sacroiliac Joint is? | Synovial, Irregular Gliding, Slightly Moveable |
| The pelvic inlet and outlet are? | Oblique Planes |
| The SI Joint is formed by the? | Auricular surfaces of the sacrum and ilium |
| _______ is an ear-shaped, articulating surface on the sacrum and ilium | SI Joint |
