TIBIA / FIBULA
TIBIA FIBULA PROJECTION
AP Projection
- The patient lies supine on the table with the long axis of the tibia and fibula in line with the long axis of the table.
- If the leg is positioned in true anatomical normal position with neither the knee or ankle joint will be projected in the "normal " AP position, therefore it is probably best to position the joint nearest the suspected anomaly in correct AP position, i.e. when the knee is in true AP position the ankle will be internally rotated more than normal.

Lateral Projection
- Patient supine
- Patient's leg fully extended on the table
- Place IR under tibia / fibula of the affected leg diagonally
- Turn the patient toward the affected side and externally rotate the leg from the hip
- Adjust rotation of the body to put the patella perpendicular to IR and the ankle in a lateral position
- Centre to the midpoint of the tibia / fibula
Technical Factors
- Entire tibia / fibula, knee joint proximally and ankle joint distally
- Midpoint of tibia / fibula perpendicular to IR
- Collimate on sides to the soft tissue borders of the tibia / fibula
- Lower margin to include ankle joint, Upper margin to include knee joint
