  1. Ankle/Lower Leg Anatomy .

  2. Bones • Name and locate the following bones: • Tarsals • Talus • Calcaneus • Cuboid • Cuneiforms (medial, middle, lateral) • Navicular • Metatarsals (5) • Tibia: Medial Malleolus • Fibula: Lateral Malleolus • Phalanges (14)

  3. Joints • Name the 8 joints of the ankles: • Distal Tibiofibular • Talofibular • Talocrural • Intertarsal • Tarsalmetatarsal • Metatarsalphalangeal • Proximal Interphalangeal • Distal Interphalangeal

  4. Ligaments • Name the ligaments of the ankle: • Lateral • Anterior Talofibular • Calcaneofibular • Posterior Talofibular • Medial • Deltoid • High • Anterior Tibiofibular

  5. Ligaments Medial Lateral

  6. Pulses • What are the two pulses in the foot and ankle: • 1. Dorsalispedis • 2. tibialis posterior

  7. Nerves • What nerves innervate the ankle and foot: • Medial plantar • Lateral plantar • Deep fibular • Superficial fibular

  8. Arches • Name the arches in the foot: • Longitudinal: • Medial • Lateral • Transverse

  9. Bony Landmarks • Name 10 bony landmarks of the foot and ankle: • PeronealTubercle • calcaneus • medial malleolus, • lateral malleolus • Talardome • navicular tubercle • head and base of 1stmetatarsal • head and base of the 5thmetatarsal • sinus tarsi • sesamoidbones (See Additional Bony Landmark Sheet for More)

  10. Terminology: Muscles • Origin • Where muscle originates and attaches to bone • Insertion • Where muscle attaches, usually distally, and where movement occurs • Plantarflexion • Ankle movement in which foot moves toward ground and toes are pointed • Dorsiflexion • Ankle movement in which toes/dorsum of foot moves upwards towards knee

  11. Movements of the Ankle • Toes: • 1.Flexion • 2. Extension • 3. Abduction/Adduction • Foot/Ankle: • 1. Inversion • 2. Eversion • 3. Plantarflexion • 4. Dorsiflexion

  12. Muscles/Tendons • Name the muscles of the lower leg and ankle: • Posterior: soleus, gastroc • Anterior: tibilas anterior, extensor hallicuslongus, extensor digitorumlongus • Medial: Tibialis posterior, flexor digitorumlongus, flexor hallicuslongus • Lateral: peroneus longus, peroneus brevis Tendons: achilles, peroneals
