ligaments of the ankle + foot Flashcards
4 parts of the deltoid ligament
Tibionavicular, tibiocalcaneal + anterior & posterior tibiotalar parts
Where does the tibionavicular part of the deltoid ligament originate + insert?
Origin: anteromedial portion of the tibia
Insertion: tuberosity of navicular, next to margin of the plantar calcaneonavicular ligament
Structure of the calcaneus in which the tibiocalcaneal part of the deltoid ligament inserts
Sustentaculum tali
The anterior tibiotalar part of the deltoid lig. inserts into…
The medial portion of the neck of the talus
The posterior tibiotalar part of the deltoid ligament inserts into…
The medial surface + medial tubercle (in posterior process) of the talus
The subtalar joint allows for…
Inversion + eversion
The talocalcaneonavicular joint is made up of… (ligaments)
Posterior: interosseous talocalcaneal lig.
Superior: dorsal talonavicular lig.
Medial: plantar calcaneonavicular lig.
Lateral: calcaneonavicular lig. (Bifurcate lig.)
The bifurcate lig. is made up of
The calcaneonavicular + calcaneocuboid lig.
Both the talocalcaneonavicular + calcaneocuboid joint allow for…
Inversion + eversion
The talocalcaneonavicular joint also allows for…
Pronation + supination
The calcaneocuboid joint is…
Sellar
Ligaments of the calcaneocuboid joint
Calcaneocuboid (bifurcate), short plantar + long plantar ligs.
