Traumatic Lateral Dislocation of the Great Toe Fibular Sesamoid: Case Report

Abstract

Traumatic dislocation of the hallucal sesamoids is uncommon. This case involves a 17-year-old female driver involved in a head-on collision who sustained traumatic lateral dislocation of the fibular sesamoid associated with intersesamoidal ligament disruption, partial plantar plate avulsion, and impaction fracture of the metatarsal head. The diagnosis was delayed due to incorrect interpretation of initial radiographs. In addition, the severity of the soft-tissue injury was not appreciated, possibly further delaying the diagnosis. The patient was treated with open reduction of the fibular sesamoid and reconstruction of the intersesamoidal ligament. Eight months after surgery, she had mild persistent symptoms, decreased range of motion, and near full resumption of prior activities.
