Valgus Posts

A valgus post on an orthotic is a useful tool when you are trying to get weight off of the lateral and onto the medial column of the foot. It works best with people that have adequate range of motion in the first ray complex (they can get the head of the big toe to the ground) because if you don’t have adequate range of motion, you will only force the knee to the midline which sometimes can cause patellofemoral problems.

A valgus post as a post which begins wider laterally and narrows medially. It usually begins near the tubercle of the fifth metatarsal and can extend as far up as the end of the fifth toe. The idea is as you walk across the post, it forces the foot from lateral to medial helping to sink the first ray down to the ground. It functions similar to a first ray cut out (A notch cut out of the orthotic at the head of the first metatarsal) however is generally more gradual and sometimes better tolerated.

This type of posting is often used in people with internal tibial torsion who often having a difficult time getting weight onto the first right and keeping the knee in the sagittal plane.

In this video we briefly describe how the posting works.
