What is a fun fact about the fibula?
An interesting fact about the fibula is that it can be harvested for tissue to graft onto other bones in the body. The fibula bears so little body weight that it typically has more bone mass than is needed to support the leg, making it a good tissue donor.
What do you know about tibia and fibula?
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.
How strong is the tibia?
Strength. The tibia has been modeled as taking an axial force during walking that is up to 4.7 bodyweight. Its bending moment in the sagittal plane in the late stance phase is up to 71.6 bodyweight times millimetre.
How thick is the fibula?
Structure of the Fibula The average fibula is about 390 millimeters (mm) long in adult men and about 360 mm long in adult women.
What muscles attach to the tibia?
Muscles that insert onto the tibia are the: sartorius, gracilis, quadriceps femoris, semimembranosus, semitendinosus, and popliteus muscles. Muscles that originate from the tibia are the: tibialis anterior, extensor digitorum longus, soleus, tibialis posterior, and flexor digitorum longus muscles.
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.
Can you break your fibula and still walk?
Because the fibula is not a weight-bearing bone, your doctor might allow you walk as the injury recovers. You also might be advised to use crutches, avoiding weight on the leg, until the bone heals because of the fibula’s role in ankle stability.
How big is the tibia bone?
Also Known as the Shin Bone The tibia is the main long bone of the lower leg. It is commonly known as the shin bone and is felt easily along the anterior (front) of the leg below the knee. The tibia is about 36 cm long on average.
How are tibia and fibula connected?
The tibia and fibula are the two bones of the lower leg. The tibia is located medially to the fibula and is much larger. Both are bound together with the interosseous membrane.
Why is the tibia important?
The primary function of the tibia is to accept and distribute weight across the knee and to the ankle. The tibia’s articulations with the relatively non-weight bearing fibula serve to maintain alignment of the tibia.
What are some functions of the tibia?
The tibia provides stability and bears weight for the lower leg . It provides leverage for the leg to propel a person through movement and facilitates walking, running, climbing, kicking, etc. There are many conditions that can affect the tibia. The most common injury associated with the tibia is a broken bone.
What is the joint between the talus and tibia and fibula?
Although it is typically referred to as a single joint, the ankle is actually two joints: The true ankle joint, which is composed of three bones: the talus, a small bone between the tibia and fibula and the calcaneus, or heel bone. The subtalar joint, which is composed of two bones: The ends of the bones are covered by articular cartilage.
Which tarsal bone articulates with the tibia and fibula?
Talus (L., talus, ankle) – large tarsal bone whose superior surface is smooth and rounded; – articulates with tibia and fibula above to form the ankle joint.
What is synovial joint between the talus and tibia fibula?
The talocrural joint is a synovial hinge joint that connects the distal ends of the tibia and fibula in the lower limb with the proximal end of the talus. The articulation between the tibia and the talus bears more weight than that between the smaller fibula and the talus.
