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.
