Leg and Ankle Flashcards
(26 cards)
Proximal Tibiofibular Joint
Synovial Joint- stabilized by anterior and posterior ligaments
Tibiofibular Joints
Proximal/Distal and Interosseous Membrane
Distal tibiofibular Joint
Syndesmosis- stabilized by ant and post tibiofibular ligaments
Interosseous Membrane
Provides stability to tibia and fibula
Talocrural Joint
Synovial joint (dorsiflexion and plantar flexion)
Subtalar Joint
Synovial Joint between talus and calcaneus (eversion and inversion)
Ligaments of Ankle
-Anterior talofibular
-Calcaneofibular
-Posterior talofibular
-Deltoid
Anterior Talofibular
Stabilize front of ankle (often sprained)
Calcaneofibular joint
Lateral stabilizer of ankle
Posterior talofibular ligament
stabilizes back of ankle
Deltoid Ligament
Medial Stabilizer with superficial and deep layers connecting the tibia to foot
Leg Compartments
Anterior, Lateral, Posterior
Anterior compartment
Dorsiflexion and toe extension (deep fibular nerve)
Lateral Compartment
Eversion of foot (superficial fibular nerve)
Posterior Compartment
Plantarflexion, inversion, and toe flexion (tibial nerve)
Posterior Compartment Muscles
Gastrocnemius
Soleus
Plantaris
Popliteus
Flexor dig long
Flexor Hall Long
Tibialis posterior
Lateral Compartment Muscles
Fibularis longus and brevis
Anterior Compartment Muscles
Tibialis anterior
Extensor DIg Long
Extensor hall long
Fib tertius
Tibial Nerve
Posterior Compartment, innervation to plantar surface of foot
Sural nerve
Lower leg and foot
Common Fibular Nerve
Superficial Fibular
Deep Fibular
Superficial Fibular
Lateral Compartment
Deep Fibular
Anterior Compartment
Flexor Retinaculum
Holds tendons in place behind medial malleolus- forms tarsal tunnel
