What are the parts of the fibula?
The structure of the fibula can be broken down into the head, neck, shaft, and distal end of the fibula. As the head becomes narrow distally, the fibular neck is formed. The fibular shaft lies distal to the neck and has three surfaces, lateral, medial, and posterior.
What is the fibular in anatomy?
fibula, outer of two bones of the lower leg or hind limb, presumably so named (fibula is Latin for “brooch”) because the inner bone, the tibia, and the fibula together resemble an ancient brooch, or pin. In humans the head of the fibula is joined to the head of the tibia by ligaments and does not form part of the knee.
What is the head of fibula called?
Fibula
| Proximal end | Apex – styloid process Head of the fibula – with facet to articulate with the lateral tibial condyle Short neck – with common fibular nerve behind it |
|---|---|
| Distal end | Lateral malleolus Point of ligamentous attachment |
What muscles attach to fibula?
The fibula acts as an proximal attachment for the following muscles:
- Extensor digitorum longus: Superior 3/4 of medial border.
- Extensor hallucis longus: Middle of anterior surface.
- Fibularis tertius: Inferior 1/3 of anterior surface.
- Fibularis longus: Fibular head and superior 2/3 of lateral surface.
What are the parts of the tibia?
Like other long bones, there are three parts of the tibia: proximal, shaft, and distal. The proximal part participates in the knee joint, whereas the distal part contributes to the ankle joint. The tibial shaft on the other hand offers many sites for leg muscle attachment.
What is the proximal end of the fibula called?
At the fibula’s proximal end, just below the knee, is a slightly rounded enlargement known as the head of the fibula. The head of the fibula forms the proximal (superior) tibiofibular joint with the lateral edge of the tibia.
Which bone is the fibular?
The fibula is your calf bone. It’s the smaller of the two bones in your lower leg. It gives your calf its structure and forms the top of your ankle. Your fibula also supports lots of important muscles, tendons, nerves and ligaments.
What causes fibula pain?
If the ligaments that hold the fibula to the tibia are loose or damaged, this causes too much motion or fibular head instability. The joint here between the two bones can become arthritic or swollen, which can cause pain. These ligaments include the tibiofibular and lateral collateral.
What is shin bone called?
The tibia is the shinbone, the larger of the two bones in the lower leg. The top of the tibia connects to the knee joint and the bottom connects to the ankle joint. Although this bone carries the majority of the body’s weight, it still needs the support of the fibula.
What is the distal end of the tibia called?
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.
Is fibula part of knee joint?
The knee is composed of 4 bones: the femur, tibia, fibula and patella. All these bones are functional in the knee joint, except for the fibula.
Where is the fibula?
lower leg
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 is the tarsus bone?
tarsal, any of several short, angular bones that in humans make up the ankle and that—in animals that walk on their toes (e.g., dogs, cats) or on hoofs—are contained in the hock, lifted off the ground. The tarsals correspond to the carpal bones of the upper limb.
What is the calcaneus?
The calcaneus is the large bone at the heel of the foot. It is usually fractured after a fall from a great height or in a motor vehicle accident.
How do you fix fibula pain?
Ice is used to relieve the pain and reduce swelling. If no surgery is needed, crutches are used for mobility and a brace, cast, or walking boot is recommended while healing takes place. Once the area has healed, individuals can stretch and strengthen weakened joints with the help of a physical therapist.
Can you walk on a broken fibula?
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.
