Position the patient in lateral recumbent with the affected leg nearest the image receptor. Align tibia and fibula parallel to the receptor, include knee and ankle joints. Slightly flex the knee (about 10–20°) to superimpose femoral condyles; patella should be lateral (in profile). Center the central ray to the mid‑shaft of the tibia, collimate to include both joints, and place a side marker.

The lateral leg X‑ray is a side‑on view with the patient lying on the affected side (or standing) and the knee slightly flexed so the tibia and fibula lie in profile. The unaffected limb is moved out of the beam; the central ray is aimed at the midshaft. This projection demonstrates cortical alignment, anterior/posterior displacement, and fracture extent of the tibia–fibula.

The lateral side of the tibia is the outer surface of the shin bone that faces the fibula. Proximally it includes the lateral condyle with a fibular articular facet for the proximal tibiofibular joint; along the shaft it forms the interosseous border for attachment of the interosseous membrane. It provides muscle and ligament attachments and helps transmit weight to the ankle.

A tibia–fibula two‑view is a plain radiographic study that obtains two perpendicular X‑ray projections—anteroposterior (AP) and lateral—of the tibia and fibula, usually including adjacent knee and ankle joints. It assesses fractures, bone alignment, joint involvement, infection, or tumor, and helps guide treatment. Images can be taken weight‑bearing or non‑weight‑bearing depending on clinical need.

The fibula is the lateral bone of the lower leg; the tibia lies medially. The tibia is the larger, weight-bearing bone forming the shin and knee joint, while the thinner fibula provides lateral stability to the ankle and serves for muscle attachment. Clinically, tibial fractures more often affect weight-bearing and alignment, whereas fibular fractures commonly impact ankle stability.

Both AP (anteroposterior) and lateral radiographic views are needed because they provide orthogonal perspectives showing anatomy in two planes. The AP view shows frontal relationships; the lateral shows depth and anterior–posterior displacement. Together they reduce overlap, confirm fracture location, alignment and angulation, detect joint effusion or foreign bodies, and lower the risk of missed injuries by improving localization and assessment.
