The femur series is comprised of an anteroposterior (AP), and lateral radiograph. The series is utilized to asses for abnormalities pertaining to the shaft of the femur (often requested when fringe abnormality is seen on hip or knee radiographs). It is not an effective series to assess for a neck of femur fractures or injuries of the tibial-femoral joint.
The femur radiographs are performed for a variety of indications including:
- obvious deformities
- suspected foreign body
- inability to weight bear
Due to the limitations of the image detector, these projections are often performed in two images per view to ensure inclusion of both knee and hip joints.
- demonstrates the lower limb in a natural anatomical position
- orthogonal projection to the AP view
Modified trauma projections

- modified horizontal beam lateral view
- performed in cases of bilateral femur fractures
