What is the distal end of the medial malleolus?
Each leg is supported by two bones, the tibia on the inner side (medial) of the leg and the fibula on the outer side (lateral) of the leg. The medial malleolus is the prominence on the inner side of the ankle, formed by the lower end of the tibia….

Where is the distal tip of the lateral malleolus?
Lower Leg, Ankle, and Foot The lateral malleolus is palpated at the distal extent of the fibula. It should be noted that the lateral malleolus extends further distally and lies more posterior than the medial malleolus.
Is the medial malleolus is the distal end of the fibula?
The expanded distal end of the fibula is the lateral malleolus. The posterior foot is formed by the seven tarsal bones. The talus articulates superiorly with the distal tibia, the medial malleolus of the tibia, and the lateral malleolus of the fibula to form the ankle joint.
What bone articulates with the lateral malleolus?
talus bone
The deep (medial) side of the lateral malleolus articulates with the talus bone of the foot as part of the ankle joint. The distal fibula also articulates with the fibular notch of the tibia.
What attaches to the lateral malleolus?
On the lateral side of the ankle are three ligaments running from the lateral malleolus of the fibula. Two of these – the anterior talofibular ligament, and the posterior talofibular ligament- attach to the talus. The third calcaneofibular ligament attaches to the calcaneus, or heel bone.
What is distal end fibula?
The distal end of the fibula forms the lateral malleolus which articulates with the lateral talus, creating part of the lateral ankle. The posterior and lateral tibia form the posterior and medial malleolus, respectively.
What is the function of the lateral malleolus?
Lateral Ligament The lateral ligaments stabilize the ankle, and serve as a guide to direct ankle motion by attaching the lateral malleolus to the bones below the ankle joint. They are responsible for resistance against inversion and internal rotation stress.
Where is distal end of fibula?
The distal end of the fibula forms the lateral malleolus of the lower limb. This is a bony projection noted on the lateral surface of the ankle, which is complementary to another bony projection on the medial aspect of the ankle called the medial malleolus (formed by the tibia).
What is medial and lateral malleolus?
The medial malleolus is formed by the lower part of your tibia and makes up the inner side of the ankle. The lateral malleolus is formed by the lower section of the fibula and makes up the outer side of the ankle.
What tarsal articulates with the lateral and medial malleolus?
the talus bone
Tarsal Bones Three areas of articulation form the ankle joint: The superomedial surface of the talus bone articulates with the medial malleolus of the tibia, the top of the talus articulates with the distal end of the tibia, and the lateral side of the talus articulates with the lateral malleolus of the fibula.
What is the lateral malleolus and what does it do?
The knob on the outside of the ankle, the lateral malleolus, is the end of the fibula, the smaller bone in the lower leg. When this part of the bone fractures, or breaks, it’s called a lateral malleolar fracture.
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. The anterior surface of the lateral malleolus lies partly within the ankle joint.
