There are several bones in the Ankle. However, the one most commonly referred to as the "Ankle Bone" (the knob-like bone that protrudes out from where the ankle rotates) is called the Medial Malleolus.
The lateral malleolus is the bone marking that can be palpated at the distal end of the fibula. This structure is the bump at the outside of your ankle.
The structure of the ankle is comprised of many bones, ligaments, and muscles ranging from above the calcaneous(Heel bone) and the top of the footdown to the toes. The "Ankle bone" (bone that protrudes out) is called the malleolus. Most people commonly confuse this for the ankle bone. when it is really one of many.
A malleolus is found on the ankle bone. There are two malleoli; the lateral malleolus on the outer side of the ankle and the medial malleolus on the inner side. Together, they help stabilize the ankle joint.
The bone that forms the bony knob on the inside of the ankle is the talus bone. This knob is called the medial malleolus, which is a prominent landmark on the inner side of the ankle joint.
The leg bone
The ankle is formed by three bones: the tibia, fibula, and talus.
When the fractured bone protrudes from the skin, this is known as a compound fracture.
Ankle bone
I think they are inner and outer ankle The Medial malleolus if found on the Tibia and the Lateral malleolus is found on the Fibula. The ankle connect to the Medial and Lateral malleolus.
