Function:

  • Everts the forefoot
  • Twists the frame into valgus

Clinical Indication:

  • Supination
  • Cavus foot due to rigid first ray

Valgus extrinsic forefoot bar post

About:
A valgus extrinsic (bar) post is semi-rigid to very rigid (45-75 Shore A) EVA material added to the inferior distal frame. It begins approximately 2cm proximal from the distal edge on the lateral side and terminates at the distal frame. The extrinsic bar also decreases in height as it extends across the device to the medial side of the orthosis. The height and amount of material added is dependent on the desired angulation. A forefoot extrinsic bar post becomes a ‘tip’ post when it has an angulation between 0°-2° because the minimal amount of material used. A tip post doesn’t extend to the medial side.

Because 2°-6° posts raise the distal lateral frame, a “drop off” will be created. If higher valgus correction is desired, this modification can be paired with valgus intrinsic forefoot posting.

Note: Bar posts are recommended for frames calibrated to neutral or higher in thickness and not recommended for flexible or EVA frames.

*CLINICAL PEARL
0° valgus forefoot posts can also be applied to prevent orthotic frame ‘bite’ or cut in the shoe, which reduces the orthotic effectiveness and shortens shoe life.
