Tibia and fibula series

The tibia/fibula is comprised of an anteroposterior (AP), and lateral radiograph. The series is often used in emergency departments to evaluate the entirety of the tibia and fibula after trauma.

  • trauma
  • obvious deformity following major midshaft impaction 
  • suspected foreign body 
  • inability to weight bear
  • osteomyelitis
