Irreducible Dislocation of Great Toe Interphalangeal Joint by an Accessory Sesamoid Bone: A Case Report and Review of Literature

Abstract

ABSTRACT Irreducible dislocation of interphalangeal joint is a rare condition with only a few case reports in literature. Here, we report a case with irreducible dislocation of interphalangeal joint due to sesamoid bone interposition, which required open reduction. A 45-year-old male had a fall from height with irreducible dislocation of interphalangeal joint of great toe. Intraoperatively, the interposition of sesamoid bone over the dorsal aspect of proximal phalanx was identified. Displaced volar plate with sesamoid bone was reduced into the position, and the joint was stabilized with k wire. On follow-up, we observed that the patient had no discomfort or pain for 6 months. The displacement of sesamoid bone with volar plate and intact collateral ligaments locks the joint in extension and obstructs the reduction of interphalangeal joint dislocation. One should have the suspicion of possibility of open reduction after observing the interposition of sesamoid bone over the dorsal aspect of the proximal phalanx. Dorsal approach is usually advocated; medial approach can be used if there is wound over the plantar aspect. How to cite this article Silvampatti S, Rajasekaran S.
