Your fibula.
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 bottom of the tibia. That particular part of the tibia is called the medial malleolus.
The leg bone
An ankle bony protuberance refers to a noticeable bony prominence around the ankle joint, commonly associated with the lateral malleolus (the outer ankle bone) or the medial malleolus (the inner ankle bone). These protuberances serve as attachment points for ligaments and tendons and play a crucial role in ankle stability and movement. While they are normal anatomical features, excessive protrusion may sometimes indicate conditions such as bone spurs or other underlying issues.
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.

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.
