Overview

The outlet view projects the sacrum and pubic rami to evaluate vertical displacement of the pelvic ring. The beam is angled cephalad to visualize the sacral foramina and pubic symphysis. This projection is useful in trauma to assess vertical shear injuries.

Technique

Angle the tube cephalad typically 40 degrees and center to the pubic symphysis. Keep the patient supine and immobilized to avoid motion. Use appropriate exposure to penetrate pelvic structures.

Clinical Indications

Outlet views are indicated for suspected vertical pelvic displacement and sacral fractures. They complement inlet and AP views for comprehensive pelvic trauma evaluation. CT provides detailed assessment for surgical planning.

Image Assessment

Evaluate sacral alignment pubic symphysis height and vertical displacement of hemipelvis. Inspect for sacral fractures and sacroiliac widening. Document measurements and recommend advanced imaging when indicated.
