Medial column instability is a primary deforming force in the setting of pes planovalgus deformity. Consideration for medial column stabilization only after correction of the hindfoot deformity may result in creating a rigid hindfoot, compromising clinical outcomes. Careful analysis of the lateral radiograph to determine whether the deformity is secondary to the medial column or true peritalar subluxation may allow superior outcomes. Iatrogenic creation of an excessively rigid medial column may lead to significant instability of the remaining joints in the short term and arthrosis in the long term. Medial column arthrodesis should be used selectively to correct gross instability.
