Ankle Study

AP Projection

1. Patient in supine;
2. Lower limb extended;
3. Dorsiflexion of the foot at 90º;
4. Medial rotation at 15º.

Central ray perpendicular to the ankle joint at middle at the malleoli.

Evaluation Criteria:

• Visualization of the tibiotalar joint space;
• Talus slightly overlapped to the distal fibula;
• Visualization of the both malleolis;
• Appropriate exposure values (visualization of the all bony trabeculation and soft tissue).

Lateral Projection

1. Patient in supine and then turn toward to the affected side until it is in lateral position;
2. Dorsiflexion of the foot at 90º.

Central ray perpendicular to the medial malleolus.

Evaluation Criteria:

• Visualization of the both malleolus superimposed;
• Fibula overlapped to the posterior half of the tibia;
• Appropriate exposure values (visualization of the all bony trabeculation and soft tissue).
