Outcome of fusion of a painful accessory navicular to the primary navicular.

Background: An accessory navicular bone may cause pain due to continuous irritation at its interface with the navicular. The authors performed the fusion of the accessory navicular and navicular with screw(s) to relieve the symptoms while preserving the continuity of the posterior tibial tendon.

Materials And Methods: We analyzed the clinical and radiological outcomes of 31 consecutive patients (34 feet) with a painful type II accessory navicular.
