Study Notes
Overview of Leg Bones and Functionality
- The tibia is the second strongest and longest bone in the body, following the femur.
- The fibula's main function is to provide stability to the ankle and support muscles of the lower leg.
- The fibula does not directly transmit body weight; weight is primarily borne by the tibia.
Anatomical Features of the Ankle and Leg
- The bony knob on the inside of the ankle is referred to as the medial malleolus.
- The fibula articulates with the tibia at the head of the fibula.
- The flattened area on the tibia for the iliotibial band insertion is known as the lateral condyle.
Functional Anatomy in the Leg
- The interosseous membrane connects the tibia and fibula, allowing for stability and serving as a site for muscle attachment.
- The semimembranosus muscle attaches to the groove for semimembranosus located on the posterior side of the tibia.
- The fibula is not part of the knee joint.
Joint Dynamics and Ligaments
- The proximal tibiofibular joint allows a small amount of rotation of the fibula's shaft.
- The posterior (inferior) tibiofibular ligament includes a separate band known as the posterior tibiofibular ligament.
- The joint formed by the articulation of the tibia and fibula with the talus is called the ankle joint.
Ligament-related Terminology
- Tearing of the distal tibiofibular ligaments is termed a distal tibiofibular ligament tear.
- The anterior superior tibiofibular ligament is a thickened structure of the joint capsule surrounding the proximal tibiofibular joint.
- The exterior part of the joint capsule of the proximal tibiofibular joint is reinforced by the fibrous ligaments.
Additional Anatomical Considerations
- A rough area on the medial surface of the lateral malleolus serves as a site for muscle and ligament attachment.
- The fibrous joint connecting the shafts of the tibia and fibula is called the syndesmosis.
- The area where the interosseous tibiofibular ligament attaches is known as the interosseous border of the tibia and fibula.
