Abstract

Accessory navicular is a congenital anomaly appearing in the secondary ossification center on the tuberosity of the navicular that may cause flatfoot. Bipartite medial cuneiform is another rare congenital anomaly occurring as two primary ossification centers in the medial cuneiform. The authors report a rare case of symptomatic bilateral accessory navicular with bipartite medial cuneiform and flatfoot deformity in a 19-year-old man with a review of the literature.

Figure

• 

  Figure 1. (A) Anteroposterior view of both feet shows bilateral multiple brachymetatarsia and accessory navicular. (B) Standing lateral view of the left foot shows flatfoot deformity.

• 

  Figure 2. Magnetic resonance images of the left foot show bipartite medial cuneiform. Bipartite bones have horizontal articulation and distal 1/5 of articular facets are composed with synchondrosis (circle).
