The upper extremity or head of the fibula is of an irregular quadrate form, presenting above a flattened articular surface, directed upward, forward, and medialward, for articulation with a corresponding surface on the lateral condyle of the tibia.

The head of fibula is the irregularly shaped, expanded, proximal end of the bone. It is the superior continuation of its neck and contains an apex and articular facet. The head of fibula provides origin sites for the fibularis longus and soleus muscles, an insertion site for the biceps femoris muscle, and an attachment site for the fibular ...

2023年8月10日 · The fibula is a slender, cylindrical leg bone that is located on the posterior portion of the limb. It is found next to another long bone known as the tibia. A long bone is defined as one whose body is longer than it is wide. Like other long bones, the fibula has a proximal end (with a head and neck), a shaft, and a distal end.

2019年8月18日 · The fibula is a bone located within the lateral aspect of the leg. Its main function is to act as an attachment for muscles, and not as a weight-bearer. It has three main articulations: Proximal tibiofibular joint – articulates with the lateral condyle of the tibia. Distal tibiofibular joint – articulates with the fibular notch of the tibia.

2022年5月23日 · What does the fibula look like? The fibula has a wedge-shaped end where it meets the tibia just below your knee, a long middle shaft and a notch at the bottom where it forms your ankle. Even though it’s one long bone, your fibula is made up of several parts. These include: Fibula head (proximal aspect)

The head of fibula provides attachment points for the biceps femoris tendon and the fibular collateral ligament. Additionally, several muscles originating from the fibula’s shaft extend upward to reach the fibula’s head, including the extensor digitorum, peroneus longus, and soleus muscles.

2020年12月13日 · The head of the fibula is an expansion of the fibula at the proximal end, and is flattened superiorly and medially forming a surface for articulation with the lateral condyle of the tibia. The head of the fibula provides the point of attachment for several muscles and ligaments, including the biceps femoris and the lateral collateral ligament ...

2024年5月7日 · The fibular head plays an important role in maintaining knee and ankle stability while anchoring key muscles and ligaments that enable smooth movement. Understanding the anatomy, common injuries, imaging and treatment methods enables proper …

2023年5月23日 · 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.

2025年2月11日 · 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. From the proximal tibiofibular joint, the fibula extends slightly medially and anteriorly in a straight line toward the ...
