Joint replacement should be staged if there is tibia vara. The tibial osteotomy can, however, be performed simultaneously with the ankle replacement. Bone quality. In other types of fractures, the injury moves the bone fragments out of alignment. If you fracture your tibia or fibula, you might need ORIF to bring your bones back.

The tibia (plural tibiae or tibias), also known as the shinbone or shankbone, is the larger, stronger, and anterior (frontal) of the two in the below the in (the other being the, behind and to the outside of the tibia), and it connects the knee with the. The tibia is found on the side of the leg next to the and closer to the or centre-line. The tibia is connected to the fibula by the, forming a type of called a with very little movement. The tibia is named for the flute.
It is the second largest bone in the next to the. The leg bones are the strongest as they support the rest of the body.
Contents.Structure In, the tibia is the second largest bone next to the. As in other vertebrates the tibia is one of two bones in the lower leg, the other being the fibula, and is a component of the knee and ankle joints.The or formation of the bone starts from three centers; one in the shaft and one in each extremity.The tibia is categorized as a and is as such composed of a and two. The diaphysis is the midsection of the tibia, also known as the or body. While the epiphyses are the two rounded extremities of the bone; an (also known as superior or proximal) closest to the and a (also known as inferior or distal) closest to the. The tibia is most contracted in the lower third and the distal extremity is smaller than the proximal.
KneeThe proximal or upper extremity of the tibia is expanded in the transverse plane with a and, which are both flattened in the horizontal plane. The medial condyle is the larger of the two and is better supported over the. The upper surfaces of the condyles with the femur to form the tibiofemoral joint, the weightbearing part of the kneejoint.The medial and lateral condyle are separated by the, where the and the attach. Here the and forms the. Together with the medial and lateral condyle the intercondylar region forms the, which both articulates with and is anchored to the. The intercondylar eminence divides the intercondylar area into an.
The anterolateral region of the anterior intercondylar area are perforated by numerous small openings for.The articular surfaces of both condyles are concave, particularly centrally. The flatter outer margins are in contact with the menisci. The medial condyles superior surface is oval in form and extends laterally onto the side of. The lateral condyles superior surface is more circular in form and its medial edge extends onto the side of the. The posterior surface of the medial condyle bears a horizontal groove for part of the attachment of the, whereas the lateral condyle has a circular facet for articulation with the.Beneath the condyles is the which serves for attachment of the, a continuation of the. Bones of the right leg. Anterior surfaceThe shaft or body of the tibia is triangular in cross-section and forms three borders: An anterior, medial and lateral or interosseous border.
These three borders form three surfaces; the medial, lateral and posterior.The forward flat part of the tibia is called the fibia, often confused with the fibula. Borders The anterior crest or border, the most prominent of the three, commences above at the, and ends below at the anterior margin of the. Lower extremity of tibia seen from the backThe distal end of the tibia is much smaller than the proximal end and presents five surfaces; it is prolonged downward on its medial side as a strong pyramidal process, the. The lower extremity of the tibia together with the fibula and forms the.Surfaces The inferior articular surface is quadrilateral, and smooth for articulation with the talus. It is concave from before backward, broader in front than behind, and traversed from before backward by a slight elevation, separating two depressions. Epiphysial lines of tibia and fibula in a young adult.
Anterior aspect.The tibia is from three; a for the (shaft) and a secondary center for each (extremity).
