What is AP of hip?

The AP hip is part of a radiographic series examining the anatomy of the hip joint and proximal femur.

What Is hip projection?

The lateral hip view is a radiographic projection assessing the relationship of the femoral head to the acetabulum.

Where is the CR placed for an AP projection of the pelvis?

Technical factors and patient positioning are the same as for an AP pelvis (bilateral hips) exam. The CR is placed perpendicular to the femoral neck in question, approximately 2 ½ inches (6.4 cm) distal on a line drawn perpendicular to the mid point of a line between the ASIS and the pubic symphysis.

Where is the IR centered for an AP pelvis?

Center IR midway between ASIS and pubic symphysis. If pelvis is deep, palpate for iliac crest and adjust position of IR so that its upper border will project 1 to 1.2 inches (2.5to3. 8cm) above crest.

Where do you center for an AP hip?

AP unilateral hip projection The CR is placed perpendicular to the femoral neck in question, approximately 2 ½ inches (6.4 cm) distal on a line drawn perpendicular to the mid point of a line between the ASIS and the pubic symphysis. In other words, the CR is directed 1-2 inches (2.5-5 cm) distal to mid femoral neck.

What is the central ray angle for an AP projection of the hip?

Central ray Directed through acetabulum at an angle of 12 degrees cephalad.

What type of CR angle is required for the AP axial projection?

The central-ray angle for an AP axial projection of the clavicle when performed on a patient in the supine position is 15-30 degrees caudal. For an AP axial clavicle projection, the central ray is angled 15- 30 degrees caudal.

What Cr angle is required for the AP axial inlet projection?

– AP requires two projections. The first is done with tube in front of the patient with a CR angle of 15 degrees toward the tarsals.

What is the central ray angle for an AP projection of the femur?

When should a hip be Xrayed?

Falling on the hip, or even falling hard on the knee so that it drives the thigh bone (femur) into the pelvis, usually requires an x-ray to rule out a fracture. If there is excessive pain at the joint or if the injured person cannot stand up or put any weight on the injured leg, then a hip x-ray may be necessary.

Where does AP projection of the hip take place?

Hip AP Purpose and Structures Shown Femoral head, neck and proximal 1/3 of body of femur, regions of ilium and pubic bones adjoining pubic symphysis, hip joint, and greater trochanter profile. For initial examination of hip lesion, AP projection is often obtained using an image receptor large enough to include entire pelvic girdle and upper femur.

Which is the correct radiographic view of the hip?

In addition to the AP and axial view of the hip, additional projections exist which are performed to answer specific questions, e.g., the false profile to evaluate the anterior acetabular coverage. Basic radiographic evaluation of the hip is performed with an AP pelvis view (Table 1 ).

How is the femur aligned for an AP knee?

Align femur to CR and to midline of table or IR. Rotate leg internally about 5 degree for a true AP, as for an AP knee. ( for proximal femur, 15 to 20 degree intenal leg rotation is required, as for an AP hip.) Ensure that knee joint is included on IR, considering the divergence of the x-ray beam.

When to use a horizontal beam hip radiograph?

The horizontal beam lateral hip radiograph or shoot through hip is in the purest terms the orthogonal view of the neck of the femur to the AP projection 1. The projection is used to assess the neck of the femur in profile during the investigation of a suspected neck of femur fracture 2.
