Traumatic Bifocal Luxatio Erecta Femoris and Ipsilateral Posterior Knee Dislocation

Abstract

Update This article was updated on July 7, 2023, because of a previous error. The title was incorrect. The correct title is “Traumatic Bifocal Luxatio Erecta Femoris and Ipsilateral Posterior Knee Dislocation: A Case Report.” An erratum (JBJS Case Connect. 2023;13[3]:e22.00408ER) has been published for this article. Case: A 19-year-old man sustained combined, ipsilateral inferior hip and posterior knee fracture-dislocations secondary to a motor vehicle collision. He underwent immediate closed reduction of the knee and delayed open reduction internal fixation but required emergent open hip reduction for an irreducible femoral head incarcerated on a pubic root fracture. At the 1-year follow-up, he demonstrated excellent functional outcome with painless and full hip and knee range of motion. Conclusion: Irreducible inferior femoral head dislocation in combination with a knee dislocation requires thoughtful staging and treatment but can result in satisfactory outcomes.
