Bones in the Ankle

By Bridget Bigale, PTA

What are the 7 Bones in the Ankle called?

The ankle joint is located above the foot where the lower leg and the top of the foot come together. Involving about 7 major bones, the bones in the ankle are made up of the bottom portions of the 2 lower leg bones called the Tibia and Fibula. These two bottom portions of the lower leg bones sit on top of the Talus which form the tibiotalar joint. Along the bottom aspect of the Talus, this bone sits on the top of the Calcaneus or heel of the foot. This region where the Talus and the Calcaneus come together creates the Subtalar joint.

Moving forward, towards the top and inside regions of the foot, the Talus joins together to form the Talonavicular joint at the Navicular bone. Similarly, the calcaneus joins the outer region of the foot at the Cuboid bone to form the Calcaneocuboid joint. The two bones, the Cuboid and Navicular bones then join 3 smaller bones of the Cuneiform (lateral, middle, and medial). The 2 cuneiform bones (lateral and middle) join the calcaneus to form the Calcaneocuboid joint.

Though there are many bones that come together to form the various joints of the ankle/foot complex, these articulating surfaces work together to allow for movement of the ankle/ foot which contribute to your ability to walk, push off, and/or pivot to change directions.

What Bones make up the Ankle?

  • Tibia.
  • Fibula.
  • Talus.
  • Calcaneus.
  • Navicular.
  • Cuboid.
  • Cuneiform (lateral, middle, medial).

What is the Bone that sticks out on the side of your Ankle?

When looking at an ankle, the bone that sticks out along the outside of the ankle is called the lateral malleolus. This bone is specifically the bottom, outside portion of the Fibula. The inside region of the ankle is called the medial malleolus. This is also referred to as the bottom/inside portion of the Tibia.

Bones in the Ankle Injuries

The ankle joint is one of the most commonly injured joints of the body. Along the outside regions of the ankle the supporting ligaments that can become stretched or torn, (partially or completely), resulting in instability of the ankle joint. A typical ankle sprain occurs when a patient steps onto an uneven surface and fall, causing injury to the supportive ligaments of the ankle. This fall stretches some of the ligaments located along the outside region of the ankle which usually results in increased pain, swelling, and tenderness.

Another injury that can occur to the ankle is called a fracture. A fracture usually occurs in severe circumstances where the bottom of the Fibula (outside region of the ankle) is separated or broken. This injury is typically occurs when the foot is fixed against an object and is thrown into the inverted position. This causes the ligaments of the outside regions of the ankle to be stressed or torn again resulting in increased pain, swelling, and/or tenderness.

If an event or injury has occurred that limits your ability to walk or stand for prolonged periods of time and/ or you are experiencing pain, tenderness, or swelling of the ankle please contact one of our specialist at JOI-2000 to schedule a consultation to begin treatment.
