title: Irreducible dislocation of the great toe interphalangeal joint secondary to an incarcerated sesamoid.
abstract: Irreducible dorsal dislocation of the interphalangeal (IP) joint of the great toe is rare. We report a case of a 29-year-old gentleman who presented to the Orthopaedic Surgery Specialist Outpatient Clinic with an irreducible IP joint of the great toe that had been untreated for 4 weeks. The mechanism of injury is believed to be a combination of axial loading with a hyperdorsiflexion force when the patient fell foot first into a drain. As the patient did not report severe symptoms and a true lateral radiograph was not ordered, the dislocation was missed initially at the emergency department. The patient had continued to run and play field hockey prior to visiting us. Incarceration of the sesamoid became a block to manipulation and reduction at the specialist outpatient clinic 3 weeks later. The patient was treated with open surgical exploration, resection of the interposed sesamoid, and Kirschner-wire fixation of the IP joint followed by occupational therapy for mobilization exercises. The operative course was uneventful. At 6 months after surgery, the patient could walk, run, and return to sports.
