The complex motion of the subtalar joint occurs in three planes and produces subtalar inversion and eversion. Along with the transverse tarsal joint (i.e. talonavicular and calcaneocuboid joint), the subtalar joint transforms tibial rotation into forefoot supination and pronation. The axis of rotation in the joint is directed upward 42 degrees ...
The joint allows inversion and eversion of the foot, but plays minimal role in dorsiflexion or plantarflexion of the foot. [5] The centre of rotation of the subtalar joint is thought to be in the region of the middle facet. [3] It is considered a plane synovial joint, also commonly referred to as a gliding joint. [6]
Pronation is a natural movement of the foot that occurs during foot landing while running or walking. Composed of three cardinal plane components: subtalar eversion, ankle dorsiflexion, and forefoot abduction, [1] [2] these three distinct motions of the foot occur simultaneously during the pronation phase.

Anatomical terms of bone [ edit on Wikidata ] The talus ( / ˈ t eɪ l ə s / ; Latin for ankle [ 1 ] or ankle bone; [ 2 ] pl. : tali ), talus bone , astragalus ( / ə ˈ s t r æ ɡ ə l ə s / ), or ankle bone is one of the group of foot bones known as the tarsus .
This is a list of roots, suffixes, and prefixes used in medical terminology, their meanings, and their etymologies. Most of them are combining forms in Neo-Latin and hence international scientific vocabulary. There are a few general rules about how they combine.
In common usage, the term ankle refers exclusively to the ankle region. In medical terminology, "ankle" (without qualifiers) can refer broadly to the region or specifically to the talocrural joint. [1] [6] The main bones of the ankle region are the talus (in the foot), the tibia, and fibula (both in the leg).
Anatomical terms of bone [ edit on Wikidata ] In humans and many other primates, the calcaneus ( / k æ l ˈ k eɪ n i ə s / ; from the Latin calcaneus or calcaneum , meaning heel; [ 1 ] pl. : calcanei or calcanea ) or heel bone is a bone of the tarsus of the foot which constitutes the heel .
The foot (pl.: feet) is an anatomical structure found in many vertebrates.It is the terminal portion of a limb which bears weight and allows locomotion.In many animals with feet, the foot is a separate [clarification needed] organ at the terminal part of the leg made up of one or more segments or bones, generally including claws and/or nails.
