PA view demonstrated mild soft tissue swelling over the first metatarsophalangeal joint. No acute fracture. Bipartite tibial sesamoid (abductor hallucis tendon sesamoid) bone incidentally noted. Oblique view showed acute transverse fracture through tibial sesamoid bone (abductor hallucis tendon sesamoid) which was interpreted as a bipartite sesamoid bone on AP view.
