About the Ankle

The ankle is the joint that connects the bones in the lower leg to the foot bones. It can be divided into two parts: the upper and lower ankle.

The upper ankle allows us to move our feet upwards, downwards, and a little to the side. It is made up of three bones:

The lower ankle connects the anklebone to the bones in the tarsus (the midfoot and hindfoot) and the heel bone. It does not move as much as the upper ankle. The lower ankle allows the foot to tilt to the side a bit and also turn inwards and outwards. Turning your foot outwards is known as pronation, and turning it inwards is called supination...

Terms to know

Ankle Fracture (Broken Ankle)
An ankle fracture is a break of the ankle bones.
Calcaneal Tendon (Achilles Tendon)
The tendon that connects the heel bone to the calf muscles at the back of the lower leg.
Chronic Ankle Instability
Returning to activity before sprained ligaments have fully healed may cause them to heal in a stretched position, resulting in less stability at the ankle joint. This can lead to a condition known as Chronic Ankle Instability (CAI), and an increased risk of ankle sprains.
Fibula (Calf Bone)
The fibula or calf bone is a leg bone located on the side of the tibia, with which it is connected above and below. It is the smaller of the two bones, and, in proportion to its length, the slenderest of all the long bones.
Joints
In medicine, the place where two or more bones are connected. Examples include the shoulder, elbow, knee, and jaw.
Ligaments
Band of fibrous tissue connecting bone to bone or cartilage to bone thereby supporting or strengthening a joint.
Sprained Ankle
A common medical condition where one or more of the ligaments of the ankle is torn or partially torn.
Talus (Ankle Bone)
The bone of the foot that connects with the tibia and fibula to form the ankle joint.
Tarsal Bones (Tarsus)
Any one of the seven bones forming the instep of the foot.
Tibia (Shin Bone)
The larger of two bones between the knee and ankle. Also called shinbone.
