Exam 7: Femur and Pelvic Girdle

Which of the following pathologic conditions is a common type of aseptic or ischemic necrosis?

Which of the following projections requires that the IR be tilted 15° from the vertical plane?

Select the correct gender to correspond with the following pelvic characteristics.More oval or heart-shaped pelvic inlet:

What type of CR angle is required for the posterior axial oblique projection for the acetabulum (Teufel method)?

A patient comes to radiology with a request for a right hip study.He is from an extended care facility and is confused about the cause of the injury.The technologist takes an AP pelvis, and when the lateral frog-leg projection is attempted, the patient complains loudly about the pain in his affected hip.What should the technologist do to complete the study?

A nontrauma patient comes to radiology with a history of chronic pain of the right hip.The patient is ambulatory but has not had previous radiographs taken of that hip.Which of the following routines would be best suited for this patient?

Which of the following structures is not an aspect of the proximal femur?

The image receptor must be placed parallel to the femoral neck for the axiolateral (inferosuperior) projection of the hip.

Which of the following pathologic conditions often occurs in males older than the age of 45 years?

How much CR angle, from the horizontal, is required for the modified axiolateral (Clements-Nakayama) projection?

Why must the lower limb be rotated 15° to 20° internally for AP pelvis projection (nontrauma)?

Match the correct disease or condition with the corresponding pathologic description. (Use each choice only once.) -Malignancy spread to bone via the circulatory, lymphatic systems, or direct invasion

A PA axial oblique projection (Teufel method) is performed on a patient.The resultant radiograph demonstrates distortion of the acetabulum.The following positioning factors were used: 40° anterior oblique, 12° cephalad CR angle, and CR centered to the upside hip (acetabulum).What needs to be modified during the repeat exposure?

The sacroiliac joints are classified as ____ joints with ____ mobility.

Gonadal shielding of the male patient for the AP pelvis projection requires that the top of the shield is not extended above the level of:

A radiograph of a unilateral frog-leg (modified Cleaves method) projection reveals that the femoral neck is foreshortened and distorted.The radiologist is concerned about pathology involving the neck.What can the technologist do to improve the visibility of the femoral neck without foreshortening during the repeat exposure?

Generally, gonadal shielding for adult females cannot be used for an initial AP pelvis for pelvic trauma due to the possibility of covering pertinent anatomy.

How much rotation of the body is required for posterior axial oblique projection for acetabulum (Teufel method)?

The term pelvic girdle refers to the total pelvis including the sacrum and coccyx.

Which of the labeled structures is the superior ramus of pubis?
