Ankle Joint Flashcards
What type of joint is the ankle joint?
Hinge-type synovial joint
Which bones make up the ankle joint?
Tibia, fibula and talus
What movements are possible at the ankle joint?
Dorsiflexion and plantarflexion
What bones make up the subtalar joint?
Talus and calcaneus bones
What movements are possible at the subtalar joint?
Eversion and inversion
What bones make up the transverse talar joint?
Calcaneus and cuboid
Navicular and talus
Why is dorsiflexion more stable than plantarflexion?
In dorsiflexion the widest part of talus (anterior) moves between malleoli - ‘better grip’
What are the lateral ligaments of the ankle?
Anterior talofibular, posterior talofibular and calcaneofibular
What is the other name for the medial ligament?
Deltoid ligament
What makes up the medial/deltoid ligament?
Tibiocalcaneal, tibionavicular, anterior tibiotalar and posterior tibiotalar parts
Are most ankle sprains inversion or eversion injuries?
Inversion
What is hallux abducto valgus?
Bunion
Medial deviation of first metatarsal and lateral deviation of hallux
What are the arches of the foot called?
Medial longitudinal arch, lateral longitudinal arch and transverse arch
How are the arches in the foot supported passively?
