title: Spontaneous ejection of a ring sequestrum in a 10-year-old: a case report.
abstract: A case of a 10-year-old patient with a femur fracture treated with an external fixator who subsequently went on to develop a free-floating ring sequestrum is presented. The patient was largely asymptomatic throughout his course of treatment until seen emergently at 2 years postinjury with local and systemic signs of infection. He was successfully treated with intravenous and oral antibiotics as well as thorough irrigation and debridement. Ring sequestrum is the end point for pin tract infection that is left untreated. When it occurs, a course of antibiotics and thorough irrigation and debridement can lead to a successful outcome.
