Rearfoot: Valgus Intrinsic

Valgus intrinsic of frame rearfoot post

Function:
Stabilizes inverting rearfoot
Eversion of heel at heel strike
Increases orthotic reaction force lateral to STJ

Clinical Indication:
Oversupination of subtalar joint
Dress and low volume shoe gear

ABOUT
A valgus intrinsic rearfoot posting is a leveled, flat surface on the inferior heel cup area of a device’s frame. This modification increases the contact area of the device. An angulation can also be ground into the inferior frame’s rearfoot to achieve a valgus rearfoot posting. The distal lateral edge of the orthotic frame will elevate matching the angulation of the rearfoot posting angle.

*CLINICAL PEARL
The angle of the weight-bearing achilles insertion bisection line relative to the normal force vector line can be used as an indication to determine the adequate degree of rearfoot posting to achieve equilibrium around the adjacent lower extremity structures during ambulation.
