One-week-old irreducible hallucal interphalangeal joint dorsomedial dislocation due to an incarcerated sesamoid: A case report and its review of literature

Abstract

Among the dislocations around the great toe, hallucal interphalangeal (IP) dislocation is a rare entity, with the most common being metatarsophalangeal dislocation due to its greater lever arm. We present the case of a young manual labourer with a missed hallucal IP joint dislocation with an incarcerated sesamoid, initially managed by an osteopath. After a failed attempt of closed reduction in the emergency department, we performed open reduction and reposition of sesamoid using dorsal incision and stabilized the joint with a K wire which was removed after 4 weeks. The patient was gradually mobilized and returned to his work of manual labor after 3 months without any residual pain or deformity.
