What is calcaneal eversion?

Calcaneal eversion occurs in the frontal plane. It is one component of the tri-plane motion of pronation of the subtalar joint (STJ). The calcaneal eversion results from the striking the lateral aspect of the heel when we walk. The ground reaction force (GRF) forces the calcaneus to evert.

How is calcaneal eversion measured?

Calcaneal eversion is measured as the angle between the bisector of the posterior surface of the calcaneus and a vertical line in the relaxed calcaneal stance position: preferred foot angle and stance base.

What causes calcaneal eversion?

Though, trunk rotation does not occur in accordance with pelvic rotation, rotation of the spine, which is a cause of calcaneal eversion, increases between the trunk and the pelvis.

Is supination an eversion?

In short, inversion/eversion are frontal plane motions of the ankle, whereas pronation/supination are triplanar motions of the foot/ankle complex. Inversion (i.e. – inversion ankle sprains) is often used interchangeably with supination, as is eversion with pronation, but they aren’t exactly the same.

Which is the correct description of the calcaneal eversion?

Calcaneal Eversion: The Switch. The motion in the frontal and transverse planes at the STJ complements the ankle joint motion, which occurs primarily in the sagittal plane, to allow the rearfoot to move in all three planes. The calcaneal eversion results from the striking the lateral aspect of the heel when we walk.

What is the axial view of the calcaneum?

Calcaneus (axial view) The calcaneus axial view is part of the two view calcaneus series assessing the talocalcaneal joint and plantar aspects of the calcaneus. As technology advances, computed tomography (CT) has widely been used 1 to better visualize and characterize calcaneum fragment displacements and fracture lines.

Which is the best view of the calcaneus?

Calcaneus axial view is part of the two view calcaneus series, this projection is best used to asses the talocalcaneal joint and plantar aspects of the calcaneus. The axial view has a diagnostic sensitivity of 87% for calcaneus fractures 1. Article:

Are there foot orthotics that help with calcaneal eversion?

Conclusions: Foot orthotics have a significant effect on calcaneal eversion and shoes also should be considered in conjunction with foot orthotic prescription. / Orthop Sports Phys
