What is unique about the fibula?
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.
How do you describe a fibula?
The fibula or calf bone is a leg bone on the lateral side of the tibia, to which it is connected above and below. It is the smaller of the two bones and, in proportion to its length, the most slender of all the long bones.
What is the shape of the fibula?
The fibula is slim and roughly four-sided, and its shape varies with the strength of the attached muscles. In many mammals, such as the horse and the rabbit, the fibula is fused for part of its length with the tibia.
Can you walk without a fibula?
The fibula is a long, thin bone of the outer leg alongside the shinbone. It is sometimes used to harvest bone that can be used in certain reconstructive surgeries of bone. The fibula can be removed without impacting the individual’s ability to walk or bear weight.
Is fibula bigger than 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.
Is the fibula on the inside or outside?
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.
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.
Can a fibula be replaced?
It is sometimes used to harvest bone that can be used in certain reconstructive surgeries of bone. The fibula can be removed without impacting the individual’s ability to walk or bear weight. Conditions that cause bony defects where fibula bone can be used in repair: Cancer damage to the bone.
Does fibula grow back?
Fibula regenerate in a 7-year-old boy 2 months after fibula resection (10 cm) used for autogenous bone transplantation. Hypertrophic bone formation can be seen at the distal regeneration side with initial signs of early gap fusion.
What are the facial features of the Korean people?
The Koreans’ facial features. Korean people have more slanted eyes than Japanese. Their outer eye corners are higher than those of Japanese. Chinese and Japanese sometimes lift their outer eye corner up with their hands to mimic the faces of Korean people. But even Korean people can open up their eyes if they want to,…
What are the different types of fibula shapes?
There are three distinct types of fibula shapes when viewed as a cross-section along the shaft: triangular, quadrilateral, and irregular. Each fibula can contain more than one type of cross-section shape, and the combinations differ between males and females. The fibula is the most slender long bone in the body as a ratio of width to length.
What part of the knee does the fibula make up?
The fibula does not make up any part of the knee joint. The distal (bottom) end of the fibula articulates with the tibia in a depression called the fibular notch and that is called the distal tibiofibular joint.
What type of bone marrow is in the fibula?
Running the length of the shaft in the center of the fibula is a cavity filled with red bone marrow. There is also red bone marrow in the trabecular bone at both ends. Separating the trabecular and compact bone is an epiphyseal plate (growth plate).
