a patient has a pelvic injury but can not roll over for a lateral. what projection can be used
Danelius-Miller “Shoot-Through” Lateral.

a patient has a pelvic injury with a fracture around the pubic syn what projection can be used.

a patient has a pelvic injury with acetabular fracture what projection can be used.
judets view.
pelvic inlet view projection
supine, 40 degrees caudad angulation, CR = level at ASIS,
exposure
kvp = 80
mas = 50
pelvic outlet view projection
supine, 35 degrees cephalad, CR = 5cm inferior to the superior aspect of the symphysis pubis
exposure
kvp = 80
mas = 50
who does the pubic syn look in an inlet and out let view
The Inlet projects the symphysis pubis inferiorly
The Outlet projects the symphysis pubis superiorly
