Bipartite medial (tibial) sesamoid at the head of the 1st metatarsal.
Case Discussion
Bipartite hallux sesamoid is a normal variant that can be seen in approximately 33% of hallux sesamoids. The essential differential diagnosis of bipartite hallux sesamoid is a fractured bone that can be challenging to differentiate. The features that support a bipartite over a fractured sesamoid include:
- transverse lucency
- smooth, well-corticated margins
