Where is the pelvic outlet?

The pelvic outlet is located at the end of the lesser pelvis, and the beginning of the pelvic wall. Its borders are: Posterior: The tip of the coccyx. Lateral: The ischial tuberosities and the inferior margin of the sacrotuberous ligament.

What is the best projection to demonstrate pelvic outlet?

– caudad projection, also called inlet view, best demonstrates ring configuration of pelvis, & narrowing or widening of diameter of ring is immediately apparent.

What forms the pelvic outlet?

The pelvic outlet is formed by the ischiopubic rami, ischial spines, inferior symphysis pubis, sacrospinous ligaments, and coccyx. Axial oblique T2WI MR at the same level shows the coccygeus muscle. It arises from the tip of the ischial spine, and the fibers fan out and insert into the lateral side of the coccyx.

What is the true pelvis?

The true pelvis contains the pelvic colon, rectum, bladder, and some of the reproductive organs. The rectum is at the back, in the curve of the sacrum and coccyx; the bladder is in front, behind the pubic symphysis.

What is the true and false pelvis?

The true pelvis contains the pelvic colon, rectum, bladder, and some of the reproductive organs. The false pelvis supports the intestines (specifically, the ileum and sigmoid colon) and transmits part of their weight to the anterior wall of the abdomen.

Are male and female pelvis different?

The female pelvis is larger and broader than the male pelvis, which is taller (owing to a higher iliac crest), narrower, and more compact. The distance between the ischium bones is small in males.

What are the landmarks of the pelvic outlet?

3 The pelvic outlet. The pelvic outlet is formed by the lower border of the pubic bones at the front, and the lower border of the sacrum at the back. The ischial spines point into this space on both sides.

How do you do a mortise view?

Patient position

  1. the patient may be supine or sitting upright with the leg straightened on the table.
  2. the leg must be rotated internally 15° to 20°, thus aligning the intermalleolar line parallel to the detector.
  3. internal rotation must be from the hip; isolated rotation of the ankle will result in a non-diagnostic image.
