| Question | Answer |
|---|---|
| Greater trochanter is on the same plane as the...? | Synthesis pubis |
| pubis forms what? | the inferior AND interior aspect of pelvic girdle |
| What bones are fused to form the acetabulum? | ilium, pubis, ischium |
| female pelvis vs. male pelvis | female - pubic arch is an obtuse angle (greater than 90 degrees) male - pubic arch is an acute angle (less than 90 degrees) |
| if the angle is between 19-24 cm, what degree angle is it? | 0 degrees |
| femur | - longest and strongest bone - patella 1/2" above joint - 5-7 degree angle between distal medial and lateral condyles |
| hip bones are innominate bones because...? | they're fused together during development |
| hip bones can also be referred to as | ossa coxae |
| blow the hip, the bones... | naturally align straight forward in anatomic position |
| if the toes are straight, the hip is ______________ if the toes are turned in, the hip is _____________ | wrong, right |
| the femoral neck naturally angles... | forward and inward |
| if the patient is anatomic position, the hip is ____________, the femoral neck is ______________, that means it's _________________. | still rotated, foreshortened, not a true AP hip |
| Modified Cleaves method - AP bilateral Frog-Leg Pelvis | - abduct thighs approximately 45 degrees from the vertical plane to place the long axes of the femoral necks parallel with the plane of the IR |
| Taylor Method | angled 40 degrees caudad |
| Judet Method - AP Oblique acetabulum | - uses two 45 degree posterior oblique positions for diagnosing fractures of the acetabulum |
| (re: Jude Method AP oblique acetabulum), affected side elevated demonstrates _________________, affected side down demonstrates _____________________. | posterior rim and anterior column, anterior rim and posterior column |
| PA Axial oblique acetabulum | - 12 degree caudad angle, evaluation of acetabular rim fractures |
| AP unilateral hip | evaluation of hip joint |
| Danelius-Miller Method, Inferosuperior Axiolateral | unaffected leg flexed and elevated to clear anatomy |
| unilateral modified cleaves method | affected knee flexed, thigh abducted |
| clements-nakayama method | CR directed to femoral neck at 30-40 degrees mediolateral and 15-20 posteriorly from horizontal |
| In an AP pelvis, should the lesser trochanters be visualized? | No. |
| What lateral hip projection cannot be perofrmed on a trauma patient with a lateral hip fracture? | modified cleaves method |
| on a properly positioned AP hip radiograph, the nexk of the femur should be _____________ to the IR, as evidenced by the ______________ visualized in profile | parallel, greater trochanter |
| in order to place the femoral neck in profile for an AP hip radiograph, the patient should be positioned with | their leg internally rotated 15-20 degrees |
| The AP axial projection (frog leg) of the femoral neck places the patient in a supine position with the affected thigh | abducted 40 degrees from horizontal |
| AP weight-bearing knees (bilateral) | evaluation of joint space narrowing, assessment of osteoarthritis and weight bearing alignment |
| Rosenburg method - PA Axial weight-bearing knees (bilateral) | knees flexed 45 degrees, 10 caudad angle centered at knee joints, beam enters posteriorly - best demonstrates interconylar fossa - sensitive for early degenerative joint disease - shows joint space narrowing under physiologic load |
| Camp coventry (PA axial knee-intercondylar fossa) | - intercondylar fossa - tibial spines -posterior aspects of femoral condyles |
