A type 2 accessory navicular is associated with a planovalgus deformity in over one third of cases. Surgical treatment for symptomatic patients who have failed nonoperative care involves resection of the os, with or without takedown and reattachment of the tibialis posterior tendon. This does not address the planovalgus deformity that may lead to long-term dysfunction. Combining subtalar arthroereisis to correct the planovalgus deformity with a modified Kidner procedure leads to improvement of pain and function and correction of the deformity. In this article, we describe our technique for the combined procedure and address concerns with proper placement of the arthroereisis implant.
