Subtalar Joint Anatomy, Pronation, Supination and Neutral Position on Real Foot Skeleton The subtalar joint (STJ) is made up of two bones, the superiorly-located talus, and the inferiorly-located calcaneus. During range of motion of the STJ, the talus and calcaneus glide on one another on their three articular facets, the posterior, middle and anterior facets. During STJ supination, the posterior facet of the talus glides posteriorly and superiorly along the posterior facet of the calcaneus unti

Subtalar Joint Axis Spatial Location Changes with Subtalar Joint Rotational Motions The subtalar joint (STJ), is a triplanar joint made up of the articulations between the talus and calcaneus. One of the main functions of the STJ is to allow transverse plane rotations of the leg to be converted into frontal plane rotations of the foot. With STJ pronation, the calcaneus dorsiflexes, abducts, everts and posteriorly translates relative to the talus. With STJ supination, the calcaneus plantarflexes,

🔹 LearnMuscles.com 🔹 Excellence-in-education ✨ SUBTALAR JOINT -The subtalar joint is located under the talus, hence its name subtalar joint. -The subtalar joint is formed by the articulation of the talus with the calcaneus, therefore it is also known as the talocalcaneal joint. -The subtalar joint is a synovial, diarthrotic, uniaxial joint. It allows: -Pronation and Supination, which are oblique plane motions composed of: Pronation: eversion (frontal plane), abduction (transverse plane), and d

Subtalar Joint Axis Rotational and Translational Motions During Closed Kinetic Chain Pronation and Supination - Sagittal Plane Motion In this three dimensional animation of the medial view of the weightbearing foot skeleton during closed kinetic chain subtalar joint (STJ) pronation and supination, the STJ axis is noted to undergo plantarflexion during pronation and dorsiflexion during supination. As the talus plantarflexes during STJ pronation, note how the STJ axis plantarflexes along with the

Subtalar Joint Axis Rotational and Translational Motions During Closed Kinetic Chain Pronation and Supination In this three dimensional animation of the posterior, medial and dorsal view of the weightbearing foot skeleton during closed kinetic chain subtalar joint (STJ) pronation and supination, the STJ axis is noted to undergo significant internal rotation, plantarflexion and medial translation during during pronation. In addition, during STJ supination, the STJ axis undergoes external rotation
