Exam II Lecture II Flashcards
Hindfoot consists of
Talus
Calcaneus
Midfoot
Navicular
Cuboid
Cuneiforms
Forefoot
Metatarsals
Phalanges
Talotibial joint fact/type/movements
Most congruent joint in body
Synovial hinge joint
Dorsiflexion/plantarflexion
Pathological torsion of talotibial joint
External/internal tibial torsion
Medial collateral (Deltoid) ligament components
Tibionavicular
Tibiocalcaneal
Anterior tibiotalar
Posterior tibiotalar
Lateral collateral ligament components
Anterior/posterior talofibular
Calcaneofibular
What is the weakest collateral ligament of the ankle
Lateral collateral ligament
Tarsal tunnel is located where and contains
Located in talocalcaneal (subtalar) joint
Talocalcaneal ligament
Talocalcaneal (subtalar) joint movements
Inversion
-adduction, supination, plantarflexion
Eversion
-abduction, pronation, dorsiflexion
Ligaments of talocalcaneal joint
Interosseous talocalcaneal
Posterior/lateral talocalcaneal
Talocalcaneonavicular joint made of/movements
Composite joint made up of
-Talocalcaneal + talonavicular joints
Inversion/eversion
Talocalcaneonavicular joint ligament
Calcaneonavicular (spring) ligament
Helps to maintain medial longitudinal arch
Calcaneonavicular ligament route
From sustentaculum tali to inferior navicular
Continues medially with deltoid ligament
Continues laterally with bifurcate ligament
Transverse tarsal joint made up of
Talonavicular + calcaneocuboid joints
Transverse tarsal joint function
Link between hindfoot and forefoot
Adds to inversion/eversion range of foot
Compensates forefoot for hindfoot eversion
Superior/inferior extensor retinaculum is thickening of what, binds down tendons of
Thickening of anterior crural fascia Binds down anterior compartment muscles Tibialis anterior Extensor hallicus longus Extensor digitorum longus Peroneus tertius
Superior/inferior extensor retinaculum covers
Deep peroneal nerve
Anterior tibial artery
Flexor retinaculum is thickening of what, binds down tendons of
Thickening of medial crural fascia Binds down tendons of: -Flexor hallicus longus -Flexor digitorum longus -Tibialis posterior
Flexor retinaculum covers
Tibial nerve
Posterior tibial artery
Peroneal retinaculum is thickening of/binds down what
Thickening of lateral deep fascia
Binds down tendons of:
Peroneus longus
Peroneus brevis
Longitudinal plantar arches and pathologies
Medial - pes cavus
Lateral - pes planus
Plantar calcaneonavicular (spring ligament) function
Primary support for longitudinal arch
Long plantar ligament function
Primary support for lateral longitudinal arch
