The anteroposterior 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. Indications. The outlet view is of considerable importance in the management of severely injured patients presenting to emergency departments 1-5.
The slight differences in their structures creates a greater pelvic outlet, adapted to aid the process of childbirth. When comparing the two, the gynaecoid pelvis has: A wider and broader structure yet it is lighter in weight; An oval-shaped inlet compared with the heart-shaped android pelvis.
The pelvic inlet transmits several structures between the abdomen and the pelvic cavity, including elements of the reproductive, urinary, and lower digestive systems, as well as neurovasculature. Additionally, in females, it is adapted to allow the passage of a newborn's head during childbirth.
- caudad projection, also called inlet view, best demonstrates ring configuration of pelvis, & narrowing or widening of diameter of ring is immediately apparent. - evaluates for posterior displacement of pelvic ring or opening of pubic symphysis;
The true pelvis is the area between the pelvic inlet, and the pelvic outlet. In this video we go for a little tour around this area, clearly marking the boun...
The pelvic cavity (the true pelvis) predominantly contains the urinary bladder, the colon, and the internal reproductive organs. This space is enclosed between the pelvic inlet and the pelvic outlet. The pelvic outlet is the inferior opening of the pelvis that is bounded by coccyx, the ischial tuberosities, and the pubis symphysis.
The pelvic cavity opens superiorly to, and is continuous with, the abdominal cavity through the pelvic inlet. Whilst the pelvic outlet is enclosed by the pelvic floor, made of the pelvic diaphragm. There are two parts of the pelvis; greater (false) pelvis and lesser (true) pelvis.
The inlet to the pelvic canal is at the level of the sacral promontory and superior aspect of the pubic bones. The outlet is formed by the pubic arch, ischial spines, sacrotuberous ligaments, and the coccyx.
The pelvic inlet involves three of the four elements of the bony pelvis. The pelvic brim has contributions from the first sacral segment, the ilium, and the pubis, but not the ischium. The pelvic inlet is delineated by a bony crest that defines its limit (the pelvic brim).
Pelvic inlet, mid pelvis, and pelvic outlet. Plane of the pelvic inlet - between the greater and lesser pelvis, it marks is the superior aperture of the pelvis.
