Case:A 30-year-old man sustained an obturator dislocation of a left total hip prosthesis with a concomitant ipsilateral fracture of the greater trochanter following a high-energy motor-vehicle accident. With the patient under general anesthesia, the hip was successfully treated with closed reduction, as confirmed with intraoperative fluoroscopy and postoperative radiographs. Postreduction, the patient was able to mobilize with abduction restrictions and had no additional instability. Short-term follow-up showed evidence of healing of the greater trochanter.Conclusion:Obturator dislocation of a total hip prosthesis is an exceedingly rare injury. Closed reduction can be considered as a treatment option in the appropriate patient, with a satisfactory short-term outcome.
