Femur: Radiographic Anatomy - Video Lesson

Hey, everybody. Welcome to today's lesson on radiographic anatomy demonstrated on routine projections of the femur. In a previous lesson, we discussed the anatomy of the femur and which radiographic projections are routinely performed. So let's tie that information to the radiographs themselves. As a reminder, the routine radiographic projections of the femur are proximal AP and lateral and distal AP and lateral. This is because most femurs are too long to fit on one image receptor. Take a look at this radiograph. What projection is being demonstrated? How do you know? Let's find out the answers to these questions. If you said this radiograph is an AP projection of the proximal femur, you're correct. We can tell this is an AP because the proximal one third of the femur is visualized along with the acetabulum and adjacent parts of the pubis, ischium, and ilium. It is a true AP because the greater trochanter and femoral head and neck are seen in full profile.
