The tibia, also known as the shin bone, is a long bone located in the lower leg between the knee and the ankle. It is the larger of the two bones in the leg, with the other being the fibula. The tibia serves several important functions in the body, including bearing weight, providing stability, and allowing for movement of the leg.

Osteology is the study of the bones of the body, and the tibia is an important bone to consider when studying the osteology of the leg. The tibia is a long bone with a cylindrical shape and a pointed end at the top, known as the proximal end. The bottom end of the tibia, known as the distal end, is wider and flattened. The tibia is covered in a thin layer of articular cartilage, which helps to reduce friction and wear on the bone during movement.

The tibia has several bony protuberances, or prominences, that serve various functions. The medial malleolus is a bony prominence on the inner side of the ankle that forms the bony prominence of the ankle. The lateral malleolus is a similar bony prominence on the outer side of the ankle. These prominences provide stability and support for the ankle joint.

The tibia also has several important articulations, or joints, with other bones in the body. The proximal end of the tibia articulates with the femur, the bone of the upper leg, to form the knee joint. The distal end of the tibia articulates with the talus bone of the foot to form the ankle joint. These joints allow for movement of the leg, including flexion and extension of the knee and plantar and dorsiflexion of the ankle.

In addition to its role in movement and stability, the tibia also plays a role in the circulation of blood in the body. The tibia contains several blood vessels and nerves that supply blood and sensation to the lower leg and foot. The tibia is also home to the tibialis anterior muscle, which is responsible for moving the foot upward and outward.

Overall, the tibia is an important bone that plays a vital role in the movement and stability of the leg, as well as in the circulation of blood and sensation in the lower leg and foot. Understanding the osteology of the tibia is important for understanding the overall anatomy and function of the leg.

High Tibial Osteotomy Knee Surgery and Realignment

Find a Because these benefits typically fade after 8 to 10 years, this type of osteotomy is generally considered to be a way to prolong the time before a knee replacement is necessary. Viewed from the ventral aspect, the patella is shaped like a clam, with a distally pointed apex and a rounded base. Here, the tibial condyles articulate with the femoral condyles within the knee joint. The malleolar groove is dorsal. Siding the Tibia For proximal tibiae, the asymmetries between the condyles discussed above are useful for distinguishing medial from lateral. Synonyms: Tibial bone The tibia shin bone is a long bone of the Like other long bones, there are three parts of the tibia: proximal, shaft, and distal. From this view it can be seen that the apex is nonarticular.

The periosteum of the diaphysis receives nerve twigs from the overlying muscles attaching to the tibia. The medial margin extends to the lateral intercondylar tubercle. The femur articulates proximally with the acetabulum of the os coxa to form the hip joint. The diaphyseal ossification center appears at the seventh week antenatally. These muscles are ankle dorsiflexors. The broader lateral condyle is separated from the narrower, more curved in distal view , medial condyle by a broad depression known as the intercondylar fossa. But in certain patients, a high tibial osteotomy canrealign the knee to take pressure off the damaged side by wedging open the upper portion of the tibia to reconfigure the knee joint.

Sex Determination using the Femur The size of the femur, especially the diameter of the femoral head, is tightly correlated with body mass. It is subcutaneous, meaning that there is only a little fat between the bone and the lateral surface is bound by the anterior and interosseous margins and is covered by the muscles of the anterior leg compartment. Of the three borders, the anterior border is the most prominent. The articular surface of the femoral head is disrupted by the fovea capitis, an excavated depression in the otherwise smooth surface. The flat shaft surface between the medial margin and the anterior margin is not covered by any muscles in the living person and is easily palpated. The apices of this triangle correspond with the medial margin, interosseous margin, and the anterior margin of the tibia.

The medially located interosseous margin is more rounded than the anterior margin. Â The articular surfaces are separated by two small prominences, the medial and lateral intercondylar tubercles. The greater trochanter projects superiorly from the dorsal surface of the proximal tibia. The medial malleolus is merely an extension from the distal epiphysis and ossifies at seventh year of life. The fibula is the long, thin, lateral bone of the lower leg.

For more anatomical details about the tibia, take a look at the study unit provided below: Two major joint in which the tibia takes part are the knee joint and the The knee joint is certainly something that deserves special attention. Tibial fractures will typically heal within four to six months after treatment, whether it is by immobilization of the affected limb or by surgery. The head bears a proximal fibular articular surface which faces medially, towards its articulation with the corresponding articular facet on the tibia. The proximal tibia is a broad plateau which bears a medial condyle and a lateral condyle which correspond with their respective femoral condyles. The patella rides along the patellar surface on the ventral surface of the distal femur during knee extension and flexion. Distally, the femur articulates with the tibial condyles to form the knee joint.

An osteotomy may also be performed in conjunction with other joint preservation procedures in order to allow for cartilage repair tissue to grow without being subjected to excessive pressure. The lateral groove is separated by a sharp ridge from an outer area, which is for the lateral malleolus. The distal ossification center appears at the first year of life and joins the shaft at the fifteenth year in females, and the seventeenth year in males. The posterior surface is bound by the interosseous and medial margins and features the soleal line crossing this surface diagonally. The medial is smaller and fused with the distal extremity of the tibia. About eForensics provides interactive environment using real cold cases as examples for forensic anthropology techniques.

The shaft is thinnest at the junction of middle and distal thirds. These tubercles form the intercondylar eminence, which is bordered by the anterior and posterior intercondylar areas. The shaft surface between the interosseos margin and the anterior margin is also flat and relatively featureless. The latter completes the lateral groove. The linea aspera is a double ridge, with medial and lateral margins running the full length of the femoral shaft. The malleoli are bony prominences on the outer marigins of the sagittal grooves.

It is imbedded in the tendon of the biceps femoris muscle. The shaft tapers from proximal to distal. Tibia is only one of the many bones making up the human body. It is a sheet of fibrous tissue that joins the tibia and fibula in the tibiofibular syndesmosis. Severe cases can undergo surgical treatment in which intramedullary titanium nails a metal nail that is put into the medullary cavity of the bone are used for putting the parts of the broken bone back in position. Fractures are easily seen on an X-ray of the affected leg. The distal end of the tibia bears a large and expanded articular surface for the talus.

The fibula does not articulate with the femur, so it bears very little weight. The gluteus medius and gluteus minimus muscles take origin here and serve as critical hip stabilizers during walking. In addition, there is also a portion showing major motions and joint involvements as well as some clinical correlations affecting the tibia. The proximal tibia is a broad plateau upon which the femoral condyles rest, forming the knee joint. The dorsal aspect of the femur bears the linea aspera, which is the insertion point for several hip adductors and a major origin site for several knee extensors. The lateral surface exhibits a triangular notch which attaches to the fibula.

This lobe is on the ventral side. Siding the Fibula For proximal fibulae, the articular surface for the tibia faces ventral-medially. The posterior margin runs the length of the dorsal shaft surface. It articulates proximally and distally with the tibia and forms the lateral bony prominence that is palpable at the ankle, where it articulates with the talus. The proximal fibular articular facet is perched just below the lateral condyle on the dorsal aspect of the proximal tibia. The very sharp and pronounced anterior margin traverses the ventral surface of the shaft. The lateral epicondyle is separated from the lateral condyle by the popliteal groove.
