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)
Subtalar (talocalcaneal): what mobilizations assist what movements
Medial gap: eversion
Lateral gap: inversion
Distraction
Medial glide
Lateral glide
What comprises the midtarsal joint?
Calcaneocuboid and talonavicular
Talocalcanealnavicular joint: classification
Type: synovial
Subtype: gliding
Axis: none
Function: diarthrotic
Talocalcanealnavicular joint: resting position
10º plantarflexion, neutral in/eversion
Talocalcanealnavicular joint: closed pack
full supination
Talocalcanealnavicular joint: capsular pattern
supination > pronation
Talocalcanealnavicular: ROM
Inversion 20º
Eversion 10º
Talocrural ROM
Plantarflexion 50°
Dorsiflexion 20°
What muscles attach to the talus
