Anatomy of the Foot & Ankle

The foot and ankle are complex structures made up of various tendons, ligaments, muscles, bones and more. These structures are what help make movements such as walking, running and jumping possible. An injury to one tendon, ligament, muscle or bone can cause the function of the entire structure to be compromised.

Main Tendons

Tendons are strong bands of tissue that attach muscle to bone.

  • Peroneal Tendons (Peroneus Longus & Peroneus Brevis)
  • Achilles Tendon (Calcaneal Tendon)
  • Extensor Digitorum Tendons
  • Extensor Hallucis Tendons
  • Tibialis Anterior Tendon
  • Posterior Tibial Tendon

Main Muscles

Muscle tissue is essential for movement.

  • Peroneal Muscles (Peroneus Longus & Peroneus Brevis)
  • Tibialis Anterior Muscle
  • Extensor Hallucis Longus Muscle
  • Extensor Digitorum Brevis Muscle

Main Bones

Bones provide a frame to hold up the other structures.

  • Calcaneus (Heel Bone)
  • Tibia (Shin Bone)
  • Fibula (Calf Bone)
  • Cuboid
  • Navicular
  • Talus
  • Cuneiform Bones
  • Metatarsal Bones

Main Ligaments

Ligaments are flexible bands of tissue that attach bone to bone.

  • Plantar Fascia
  • Deltoid Ligament
  • Anterior Talofibular Ligament
  • Posterior Talofibular Ligament
  • Calcaneofibular Ligament
  • Lisfranc Ligaments
