Case contributed by Craig Hacking


Painful forefoot, swollen painful 1st MTP joint.

Patient Data

Age: 25 years
Gender: Female

Alignment is normal. There is a bipartite medial hallux sesamoid bone which represents a normal variant. The adjacent lateral sesamoid demonstrates an oblique linear lucency that may represent a fracture, alternatively it may represent a bipartite sesamoid.

Case Discussion

The patient reported increase in running activity recently. On further examination pain was exacerbated by hallux MTP joint hyperextension.

The large medial sesamoid in more commonly injuried than the lateral sesamoid, related to greater weight bearing.
