Surgical treatment of the accessory navicular

Surgical management of the accessory navicular or navicular beak using the Kidner procedure was indicated in 29 feet. Pain was present in all feet; difficulty with shoe fit and flat feet were other complaints. The patients were followed up for two to ten years (mean, 4.5 years) after operation. Eleven results were excellent, 15 good, and 3 poor, all in boys with a navicular beak. Only one complication occurred. Excision of the accessory navicular or navicular beak, together with suturing the fibers of the posterior tibial tendon (inserting on the accessory navicular or navicular beak) to the inferior surface of the navicular, is effective treatment.
