Which bone articulates with the tibia and fibula?

Which bone articulates with the tibia and fibula?

The articular surface for the ankle joint is a broad notch, formed by the curved undersurface of the tibia, and the inner surfaces of the medial malleolus, and the lateral malleolus. Now let’s look at the bone that articulates with the tibia and fibula to form the ankle joint – the talus.

What name is given to the distal ends of the tibia and fibula?

The talus is a cube-shaped bone that sits above the calcaneus and below the tibial plafond. The distal ends of the fibula and tibia that overlap the talus are known as the malleoli (“little hammers”). The lateral malleolus is the distal end of the fibula, whereas the medial and posterior malleoli are part of the tibia.

What is the distal end of the tibia called?

lateral malleolus
The fibular diaphysis is thin and gracile; it is slightly triangular in cross section, with a bulbous and pointed distal end known as the lateral malleolus. The anterior surface of the lateral malleolus lies partly within the ankle joint.

What bones does the tibia articulate with at its proximal and distal ends?

Proximally, the tibia articulates with the femur to form the tibial-femoral joint of the knee. Distally, the tibia articulates with the talus to form the talocrural joint of the ankle.

What is the main function of the tibia and fibula?

Structure and Function Unlike the tibia, the fibula is not a weight-bearing bone. Its main function is to combine with the tibia and provide stability to the ankle joint. The distal end of the fibula has several grooves for ligament attachments which then stabilize and provide leverage during the ankle movements.

Where the tibia and fibula meet is an example of?

A syndesmosis is similar to a suture, complete with the fibrous connective tissue, but it is more flexible. Such a joint is useful if the body needs to link two bones, but allow a little flexibility. A perfect example can be found between the tibia and the fibula.

How serious is a broken tibia and fibula?

A broken tibia-fibula is a fracture in the lower leg that happens when a fall or blow places more pressure on the bones than they can withstand. A tibia-fibula fracture is a serious injury that requires prompt immediate medical attention. With timely and proper treatment, a broken tibia-fibula can heal completely.

What is the function of tibia bone?

Structure and Function As the second-largest bone in the body, the tibia’s main function in the leg is to bear weight with the medial aspect of the tibia bearing the majority of the weight load.

How long does it take for a distal tibia fracture to heal?

Recovery from a tibia-fibula fracture typically takes about three to six months. Your child may be able to heal faster by resting and not putting too much weight on their leg until the bone has healed.

What is the bone between your legs called?

Overview. The lower leg is comprised of two bones, the tibia and the smaller fibula. The thigh bone, or femur, is the large upper leg bone that connects the lower leg bones (knee joint) to the pelvic bone (hip joint).

What is the role and function of the tibia?

How do the tibia and fibula work together?

The tibia is a larger bone on the inside, and the fibula is a smaller bone on the outside. The tibia is much thicker than the fibula. It is the main weight-bearing bone of the two. The fibula supports the tibia and helps stabilize the ankle and lower leg muscles.
