Ankle & Leg Anatomy Flashcards
Lateral ankle ligaments
anterior talofibular ligament (ATF)
calcaneofibular ligament (CF)
posterior talofibular ligament (PTF)
Medial ankle ligaments
Deltoid Ligament Anterior TIBIOTALAR ligament (ATT) Tibiocalcaneal ligament (TC) Posterior tibiotalar ligament (PTT) Tibionavicular ligament (TN)
Syndesmosis joint
relatively immobile joint in which two bones are bound together by ligaments
Distal tibiofibular syndesmosis
maintained by?
INFERIOR Anterior and Posterior tibiofibular ligaments (Tib-fib) & EXTENSION OF INTEROSSEOUS membrane crural interosseous (CI) ligament
Distal tibiofibular syndesmosis
what movements?
Rotation and slight spreading of mortise while still maintaining joint stability and allowing the fibula to glide inferiorly during weight bearing.
Ankle Mortise
Junction of tibia, fibula, and talus
Anterior Compartment Muscles
Tibialis anterior
Extensor hallucis longus
Extensor digitorum longus
Peroneal tertius
= dorsiflexors of the ankle
Lateral Compartment Muscles
Peroneus Longus
Peroneus Brevis
= plantarflexion & eversion
Triceps surae muscle group
Gastrocnemius
Soleus
= plantar flexion
Anterior Compartment Nerves & Arteries
Common Peroneal Nerve
Deep Peroneal Nerve
Anterior tibial artery
Dorsalis Pedis Artery
Lateral Compartment Structures
Peroneus Longus Peroneus Brevis Superior Peroneal Retinaculum Inferior Peroneal Retinaculum Os Peroneum Peroneus Quartus Superficial Peroneal Nerve Posterior Tibial Artery
Superficial Posterior Compartment Structures
Ticep surae muscle group
Plantaris
Tibial Nerve
Posterior Tibial Artery
Deep Posterior Compartment Structures
Tibialis Posterior (only muscle that does no act on toes)
Flexor Digitorum Longus
Flexor Hallucis Longus
= last two muscles flex toes, plantar flex, and invert ankle
Subtendinous Calcaneal Bursa
Found between Achilles tendon & calcaneous
Subcutaneous calcaneal bursa
Found between posterior aspect of Achilles tendon & skin
