Where does the proximal tibia articulate?
The superior/proximal tibiofibular joint is where the proximal end of tibia articulates with the head of the fibula. The articulation site on the tibia is found on the lateral side of its proximal part, while the fibula participates with the medial surface of its head.
What is the name of the distal articulating surface of the tibia?
The articular surfaces of the distal tibia (trochlea surface and medial malleolus) and distal fibula (lateral malleolus) form a mortise on the talus, which restricts side-to-side movement of the talus in the ankle joint.
Is the tibia distal or proximal?
While the epiphyses are the two rounded extremities of the bone; an upper (also known as superior or proximal) closest to the thigh and a lower (also known as inferior or distal) closest to the foot. The tibia is most contracted in the lower third and the distal extremity is smaller than the proximal.
What type of articulation joins the tibia and fibula?
(3) A syndesmosis is a joint in which a ligament connects two bones, allowing for a little movement (amphiarthroses). The distal joint between the tibia and fibula is an example of a syndesmosis.
What are the articulations of the tibia?
Articulations. 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.
Where is the distal tibia?
The distal tibia bears medial and posterior prominences known as the medial malleolus and posterior tibial process, respectively. The medial malleolus is longer than the lateral tibial surface and articulates with the medial surface of the talus to form the medial gutter of the ankle joint.
What are the proximal articulations of the tibia?
Which term refers to the proximal expansion of the tibia?
tibial tuberosity. What term refers to the proximal expansion of the tibia? tibial plateau.
What is tibia?
Tibia and fibula are the two long bones located in the lower leg. 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.
What type of joint is the proximal tibiofibular?
synovial joint
The proximal tibiofibular joint is a synovial joint that functions in dissipating lower leg torsional stresses and lateral tibial bending moments and in transmitting axial loads in weight-bearing [1]. Numerous disorders of the proximal tibiofibular joint can present as lateral knee pain.
What is the type of joint the proximal tibiofibular joint and distal tibiofibular joint?
The superior tibiofibular joint is a plane synovial joint, while the inferior one is a syndesmosis (fibrous joint). These joints allow no active movements.
Where does the tibia articulate with the knee?
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.
Is the tibia a distal or proximal bone?
Distal. It articulates with the tarsal bones to form part of the ankle joint. On the posterior surface of the tibia, there is a groove through which the tendon of tibialis posterior passes. Laterally is the fibular notch, where the fibula is bound to the tibia – forming the tibiofibular joint.
Where are the condyles located in the proximal tibia?
Proximal. The proximal tibia is widened by the medial and lateral condyles, which aid in weight-bearing. The condyles form a flat surface, known as the tibial plateau. This structure articulates with the femoral condyles to form the key articulation of the knee joint. Located between the condyles is a region called the intercondylar eminence –…
Which is part of the tibia forms the fibular notch?
Lateral Malleolus. The lateral aspect of the distal tibia forms the fibular notch, creating an articulation between the distal tibia and fibula, the distal tibiofibular joint. The medial malleolus is the medial surface of the distal portion of the tibia. It is prolonged downward to form a strong pyramidal process and flattened from without, inward.
