How is the part positioned for a Lateral Hip (Lauentiein Method)
Abduct femur 90 degrees from vertical; femur parallel to the tabletop
What should be demonstrated on a Lateral Hip (Lauentiein Method) radiograph
Centered at the Hip Joint, Hip Joint acetabulum and femoral head clearly illustrated, femoral neck overlapped by the greater trochanter, and soft tissue and bony trabecular detail.
what should be demonstrated on an AP Pelvis radiograph
Entire pelvis and proximal femora. Lesser trochanters on the medial border of the femora. Femoral necks without superimposition. Greater trochanters in profile. Both ilia are equidistant to the edge of the image. Both greater trochanters are equidistant from the image edge. The lower vertebral column is in the center of the image. symmetric obturator foreman. Ischial spines are equally demonstrated. symmetric ilia alae. Sacrum and coccyx aligned with public symphysis.
How should the patients legs be positioned for an AP Pelvis radiograph
Limbs rotated 15-20 degrees internally with heals separated.(non-trauma exams)
Where should the CR be directed on an AP Pelvis radiograph
Lined up with MSP; mid-way between the ASIS and pubic symphysis (2" inferior to ASIS)
How do you find the midline of the femoral neck for the CR for an AP Radiograph?
Make a line from the ASIS to the Pubic symphysis, then at the midpoint of that line go distal 2.5". CR should be perp. to the femoral neck.
What should you do as a positioning maneuver for an AP Hip Radiograph to hide the lesser trochanter?
Medially rotate the affected limb 15-20 degrees
Where should the CR be directed for an AP Hip Radiograph?
Mid femoral neck
Where should the CR be directed for a Lateral Hip (Lauentiein Method) radiograph
Midway between the ASIS and pubic symphysis (Hip Joint)
What relation does the femoral neck have with the IR on an AP Hip radiograph?
Parallel to the IR
what should be demonstrated on an AP Oblique Femoral Necks (Mod. Cleaves Method) radiograph
Pelvis is free of rotation. The acetabulum, femoral head and neck, clearly shown. Lesser trochanter on the medial side of the demur. Greater trochanter does not superimpose the femoral neck. femoral axes at equal angles from the hips.
Patient position for AP Hip radiograph?
Supine
What should be demonstrated on an AP radiograph of the Hip?
The greater trochanter in profile, femoral head penetrated and seen through the acetabulum, parts of the ilium & pubic bones joining the pubic symphysis, entire Hip joint, and proximal 1/3 of the femur. You should also see the entirety of any medically implanted device.
What should you do to the unaffected leg on an Axiolateral Hip - Cross-Table (Danelius-Miller Method) radiograph
elevate the unaffected leg
Where should the CR be directed for an Axiolateral Hip - Cross-Table (Danelius-Miller Method) radiograph
femoral neck; IR parallel to long axis of femoral neck
How will you position the patient for an AP Oblique Femoral Necks (Mod. Cleaves Method) radiograph
place the patients heels together and knees flexed; abduct femora 45 degrees.
Patient position for a Lateral Hip (Lauentiein Method) radiograph
supine
what should be demonstrated on an Axiolateral Hip - Cross-Table (Danelius-Miller Method) radiograph
the femoral neck without overlap from the greater trochanter. small amount of the lesser trochanter on posterior surface. small amount of the greater trochanter on anterior and posterior surfaces of proximal femur. soft tissue shadow of unaffected thigh not seen in anatomy of interest. Hip joint with acetabulum. any ortho decice shown in entirety. and ischial tuberosity below the femoral head.
