Pelvic Girdle: Radiographic Anatomy - Video Lesson

Hey, everybody. Welcome to today's lesson on radiographic anatomy, demonstrated on routine projections of the pelvis. In a previous lesson, we discussed the anatomy of the pelvic girdle and which radiographic projections are routinely performed. So let's tie that information to the radiographs themselves. As a reminder, the routine radiographic projection of the pelvis is the AP. We will also be discussing two special projections, the AP axial inlet and AP axial outlet projections. Let's start with the routine AP projection of the pelvis. Is it a quality radiograph? How do we know? Let's find out. We can tell this is a diagnostic quality AP projection of the pelvis because the pelvic girdle, fifth lumbar vertebrae or l five, sacrum, coccyx, and heads, necks, and greater trochanters of the femurs are all visible. We can tell there has been proper internal rotation of the legs because the lesser trochanters are not visible. It is a true AP.
