Missed obturator hip dislocation in a 19-year-old man

Traumatic obturator hip dislocations are rare injuries that are typically diagnosed and managed acutely. We encountered a patient who presented with a painful hip 2 months after sustaining an undiagnosed traumatic obturator hip dislocation. After failed closed treatment, the hip was reduced with open reduction, utilizing a Kocher approach and a trochanteric osteotomy. At 15 months postoperatively, the patient maintained a functional range of motion without clinical or radiographic signs of posttraumatic arthritis or avascular necrosis.
