Anatomy Of The Tibia And Fibula

The tibia os tibia and fibula os fibula are the bones that support the leg. It also separates muscles on the anterior and posterior parts of the leg.

The fibula provides lateral stability for the lower leg and acts as a tie rod to increase the range of motion for the ankle especially lateral and medial rotation of the foot.

Anatomy of the tibia and fibula. It bears very little body weight. The fibula is the slender long bone that is attached next to and a little below the tibia shinbone. The larger tibia or shinbone is located medial to the fibula and bears most of the weight.

When you feel your shinbone this is what youre feeling. 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.

The larger tibia or shinbone is located medial to the fibula and bears most of the weight. Compared to the tibia the fibula is about the same length but is considerably thinner. This image shows the anatomy of the fibula and tibia bones the bones of the leg in relation to each other displaying the different features and parts of them fibula on the left and the tibia on the right showing.

Laterally is the fibular notch where the fibula is bound to the tibia forming the tibiofibular joint. This membrane keeps the tibia and fibula together and provides strength and stability for them. It runs parallel to the tibia or shin bone and plays a significant role in stabilizing the ankle and supporting the muscles of the lower leg.

Now lets look at the tibia bone which is the larger of the two leg bones located medially. The fibula is the long thin and lateral bone of the lower leg.
