Case contributed by Dr Henry Knipe


High-speed MVA. Incidental finding.

Patient Data

Age: 25
Gender: Male

No fracture or malalignment. Incidental finding of bipartite lateral hallux sesamoid and bone island in third middle phalanx. 

Case Discussion

The key differential for this cause is a fracture of the hallux sesamoid. A bipartite hallux sesamoid, as in this case, has the following features:

  • transverse lucency
  • smooth, well-corticated margins
  • two bony fragments are greater in size than the other hallux sesamoid
