Ankle & Foot Flashcards
What joints comprise the ankle?
Talocrural
Subtalar
Talocrural: classification
Type: synovial
Subtype: hinge
Axis: uniaxial
Function: diarthrotic
Talocrural: articular surfaces
Tibia (concave)
Fibula (concave)
Trochlea of the talus (convex)
Talocrural: resting position
10º plantar flexion
neutral in/eversion
Talocrural: closed pack
full dorsiflexion
Talocrural: capsular pattern
plantarflexion > dorsiflexion
What talocrural mobilizations help what movements?
Posterior glide: dorsiflexion
Anterior glide: plantarflexion
Distraction
What joints comprise the subtalar joint?
Talocalcaneal and (depending on who you ask) talocalcanealnavicular
Articular surfaces of the subtalar (talocalcaneal) joint?
Posterior facet of the calcaneus
Posterior facet of the talus
Classification of the subtalar (talocalcaneal) joint?
Type: synovial
Subtype: planar
Axis: non
Function: diarthrotic
What comprises the mortise?
Internal surfaces of the malleoli, inferior surface of the distal tibia.
Articulates with talus
Subtalar (talocalcaneal) resting position:
10º plantar flexion
neutral in/eversion
Subtalar (talocalcaneal) closed pack
Full inversion
Subtalar (talocalcaneal): Capsular pattern
inversion > eversion
Tarsal sinus
Space between talus and calcaneus on lateral aspect, distal and anterior to lateral malleolus.
Has second highest number of proprioceptors (only C-spine has more)
