Evidence-Based Treatment of Accessory Navicular Bone

Abstract

Accessory navicular bone is a normal variant which can cause symptoms. Various operative and non operative treatments are used to improve symptoms. There is lack of good quality published literature on either non-operative or operative management. It is generally agreed that non-operative management in the form of symptomatic control, orthoses and physiotherapy is the first line of treatment method. Surgical options include excision of the accessory navicular bone, excision with posterior tibialis tendon reconstruction, arthrodesis of the accessory to the anatomical navicular and percutaneous drilling. Flat foot deformity should be assessed because of its potential role in the development of symptoms and need to be managed together with the accessory navicular bone.
