Reading Tibia & Fibula X-rays
Shaft pattern, plateau, and the ankle that comes with it.

At a glance
Tibia-fibula films are joint-to-joint. A shaft fracture that does not include the knee and ankle is how people miss a plateau, a pilon, or a Maisonneuve. Soft-tissue swelling and open-wound clues belong in the same read as the pattern.
Technique pointers
Series
- AP and lateral of the entire tibia and fibula
- Dedicated knee and ankle when the shaft is broken
- Look at fibular length and syndesmosis if the ankle is in play
Pattern
- Location and morphology (transverse / spiral / segmental)
- Comminution; butterfly = compression side
- Open vs closed is exam plus film (dressings, gas, spikes)
Decision-making
Spiral distal tibia wants a look at the ankle. Proximal shaft wants the plateau. Compartment risk is clinical, but a high-energy pattern on the film should make you say the word out loud in the handoff.
High-yield / exam
- Knee and ankle on the study
- Maisonneuve / syndesmosis when the fibula is high
- Open-fracture language from exam, not from hope
- Segmental and comminuted patterns change staging
