How do you XRAY your pelvis?
One to two pictures are usually taken of the pelvis, one with the legs straight from the front (anteroposterior or AP view) and one with the legs bent from the side (lateral view). The X-rays are taken while the patient is lying flat on his or her back.
Where is the pelvic inlet?
The pelvic inlet, or the upper pelvic narrow, is the anatomical limit between the true pelvis below and the false pelvis above. There are tangible, genetic, and hormonal differences between the male and female pelvis related to reproductive function.
How do I open my pelvic inlet?
The inlet of the pelvis can be opened with external rotation of the femurs, or wide knees, and a posterior pelvic tilt, or tucking the butt underneath. These tend to be the intuitive movement patterns I observe in laboring women whose babies have not yet engaged into the pelvis.
What is an outlet view?
The AP outlet view is a specialized view part of a pelvic series examining the iliac crest, sacrum, proximal femur, pubis, ischium and the great pelvic ring.
What is Clements Nakayama method?
The Clements-Nakayama view of the hip is a highly specialized lateral projection utilized on patients with bilateral femoral fractures, or patients unable to mobilize due to postoperative requirements.
Where is the center for an xray of the pelvis?
For correct centering of the pelvis (bilateral hips), palpate for the iliac crest and adjust the position of the cassette so that the upper border of the cassette is 1-1 ½ inches (2.5-3.8 cm) above the iliac crest. The center of the cassette should be midway between the ASIS and the pubic symphysis.
Is pelvic brim same as pelvic inlet?
The pelvic brim is the edge of the pelvic inlet. It is an approximately Mickey Mouse head-shaped line passing through the prominence of the sacrum, the arcuate and pectineal lines, and the upper margin of the pubic symphysis.
What are the boundaries of the pelvic inlet and outlet?
Anatomic boundaries of the pelvic outlet: Anterior: inferior margin of the pubic symphysis. Anteriolateral: inferior rami of the pubis and ischial tuberosities. Posterolateral: inferior margins of the sacrotuberous ligaments.
How is the pelvic inlet different in males vs females?
The distance between the ischium bones is small in males. This causes the sides of the male pelvis to converge from the inlet to the outlet, whereas the sides of the female pelvis are wider apart. This results in the female inlet being large and oval in shape, while the male inlet is more heart shaped.
How do you open the pelvic brim?
The inlet of the pelvis can be opened with external rotation of the femurs, or wide knees, and a posterior pelvic tilt, or tucking the butt underneath.
Where should the pelvic inlet be located at the pelvis?
Center of pelvic inlet should be at center of collimated field. Lateral margins of collimation field should extend equally on both sides to just lateral to the femoral heads and acetabula. Superior and inferior margins of field should include the ala and the symphysis pubis, respectively.
What is an outlet view of the pelvis?
The AP outlet view is a specialized view part of a pelvic series examining the iliac crest, sacrum, proximal femur, pubis, ischium and the great pelvic ring. The outlet view is of considerable importance in the management of severely injured patients presenting to emergency departments 1-5.
How should the pelvis be centered and angulated?
Proper centering and angulation are evidenced by demonstration of the superimposed anterior and posterior portions of the pelvic ring. Center of pelvic inlet should be at center of collimated field. Lateral margins of collimation field should extend equally on both sides to just lateral to the femoral heads and acetabula.
What is an AP Inlet View of the pelvic?
The AP inlet view is part of a pelvic series examining the iliac crest, sacrum, proximal femur, pubis, ischium and the great pelvic ring. It is of considerable importance in the management of severely injured patients presenting to emergency departments 1.
