Info

There is a comminuted and predominantly sagittal oriented fracture line through the proximal body of the lateral sesamoid bone. The fracture line is irregular and it appears to have sclerotic margins suggesting subacute fracture.

Case Discussion

Sesamoid fractures are not common and can be mistaken with bipartite sesamoid on plain x-ray.
