Ongoing pain and deformity after an excision of the accessory navicular

Although a painful accessory navicula and a pes planus often coexist, they are not necessarily causally related, and each condition should be assessed and treated individually. A child or adolescent will notice the rubbing of an accessory navicula against footwear as the foot and boney swelling grows. The cause of persistent local pain such as inadequate bony resection, scar pain, irritation of the tibialis posterior tendon, and so forth should be sought and addressed; management will depend on the specific presentation and previous procedure performed. The cause of the ongoing pain should be investigated.
