Femur series

Andrew Murphy et al.

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.

Indications

The femur radiographs are performed for a variety of indications including:

  • trauma
  • obvious deformities
  • suspected foreign body 
  • inability to weight bear
  • osteomyelitis 

Projections

Standard projections
  • AP
    • demonstrates the lower limb in the natural anatomical position
    • often will be performed in two x-rays due to the limitations of the image intensifier 
  • lateral
    • projection 90° to the AP  view
    • must include both the knee and hip joint
    • often will be performed in two x-rays due to the limitations of the image intensifier 
Additional projections

In the case of bilateral fractured femurs, a modified horizontal beam lateral can be performed similarly to that of the clements-nakayama
