Symptomatic Fracture of the Subhallucal Interphalangeal Sesamoid Bone: A Case Report.

The hallucal interphalangeal sesamoid bone can often be misdiagnosed when fractured and show presenting symptoms of forefoot pain. Primary presentation is asymptomatic but can become symptomatic in cases of trauma, overuse, or pressure to the area. However, even when symptomatic, misdiagnosis can often occur and lead to improper management that can exacerbate or prolong symptoms. This case is unique in revealing a rare anatomical variation and shows the proper approach to treatment and management from a prior misdiagnosis of right big toe pain without indication of a fracture.
