1. Ankle Joint Anatomy
The ankle joint is a hinge joint. It allows the foot to move up and down.
by Amol Pujari

2. Bones of the Ankle
The ankle joint is formed by 3 bones:
Tibia1.
Fibula2.
Talus3.

3. Ligaments of the Ankle
Deltoid Ligament
Strong, triangular ligament on
the inside of the ankle
Lateral Collateral
Ligaments
Three ligaments on the outside
of the ankle, including the
anterior talofibular,
calcaneofibular, and posterior
talofibular ligaments
Syndesmosis Ligaments
Connect the lower leg bones to
provide ankle stability

4. Tendons of the Ankle
Tendons connect muscles to bones.
Allow for ankle movement.

5. Joints of the Ankle
Talocrural joint
Between tibia, fibula, and talus.
Subtalar joint
Between talus and calcaneus.
Tibiofibular joint
Between tibia and fibula.

6. Movements of the Ankle
1
Dorsiflexion
Pointing toes
upwards
2
Plantarflexion
Pointing toes
downwards
3
Inversion
Turning sole of foot
inwards
4
Eversion
Turning sole of foot
outwards

7. Blood Supply to the Ankle
Ankle is supplied by the tibial artery.
Arterial blood flow is essential for healthy muscles and tendons.
Veins carry deoxygenated blood back to the heart.

8. Nerves of the Ankle
The nerves of the ankle are responsible for
providing sensation and motor control to the
foot and ankle.
The **sural nerve** provides sensation to the
outer ankle and the back of the foot.
The **deep peroneal nerve** controls the
muscles that dorsiflex the foot and toes.
The **tibial nerve** provides sensation to the
sole of the foot and controls the muscles that
plantarflex the foot and toes.

9. Common Ankle Injuries
Sprains, strains, fractures
Tendinitis, bursitis, arthritis
