A tibia–fibula two‑view is a plain X‑ray exam obtaining two standard radiographs—anteroposterior (AP) and lateral—of the tibia and fibula. It evaluates fractures, bone alignment, joint involvement (knee and ankle), growth‑plate injury in children, and soft‑tissue swelling. Views should include adjacent joints to detect injury extension and to guide urgent management or further imaging.

AP (anteroposterior) view means the X‑ray beam passes from the front (anterior) to the back (posterior) of the body—often used when patients are supine or cannot stand. Lateral view is taken from the side, with the beam passing left‑to‑right or right‑to‑left, providing depth and separation of structures. Together they localize fractures, assess alignment, and clarify chest or joint pathology.

Place the patient supine with the leg extended for an AP tibia-fibul

MRI of the tibia and fibula is a magnetic-resonance scan of the lower leg that visualizes bones, bone marrow, ligaments, tendons, muscles and surrounding soft tissues. It detects fractures including stress fractures, infections, bone tumors, ligament or tendon injuries, muscle tears and marrow edema. The test uses magnetic fields and radio waves (no ionizing radiation), may use contrast, and is contraindicated with some metal implants.

The name "tibia" comes from Latin, where tibia meant both a shinbone and a small pipe or flute. Ancient anatomists used that word because the long, slender shape of the shinbone resembled a pipe, and such bones were sometimes fashioned into flutes. Over time the Latin term became the standard anatomical name for the larger lower-leg bone.

The tibia and fibula are the two long bones of the lower leg. The tibia, or shinbone, is the larger, medial weight-bearing bone connecting knee to ankle and forming the knee joint with the femur. The fibula is the thinner, lateral bone that stabilizes the ankle, provides muscle and ligament attachment, and supports balance but bears little weight.
