Movement in the direction of eversion, abduction and dorsiflexion.
Movement toward inversion, adduction, and plantar flexion.
–Supinates (dominated most by plantar flexion with inversion and adduction)
Subtalar – Closed chain pronation (calcaneus everts, talus adducts and flexes)
– Closed chain supination (calcaneus inverts, talus adducts and dorsiflexes)
Subtalar pronation – Promotes mobility in MTJ
Subtalar supination – Promotes stability in MTJ and forefoot.
Depends on subtalar joint biomechanics
First ray hypermobility – Dorsal translation with soft endpoint.
Subtalar varus – Inverted twist within body of calcaneus.
Forefoot varus – Inversion deviation of forefoot relative to bisection of posterior calcaneus.
Forefoot valgus – Eversion deviation of forefoot relative to bisection of posterior calcaneus.
Examination of knee, hip, ankle, and spine is essential!
First degree – Complete rupture of ATFL
Second degree – Complete rupture of ATFL and CFL
Third degree – Dislocation in which ATFL, CFL, and PTFL are ruptured
