Fractures of sesamoids

Sesamoid fractures occur as a result of trauma to a previous unipartite sesamoid bone. They mostly occur in relation to the sesamoids of the foot - i.e. Hallux sesamoid or hand sesamoids.

Radiographic features

On some occasions, an acute fracture of the unipartite sesamoid can be differentiated from a congenital bipartite sesamoid using a bone scan or MRI ¹. The separated bony margins may be sharper on a radiograph.
