Abstract

Introduction: Intraprosthetic dislocation is a rare and exclusive complication of hip prostheses with dual-mobility components, where the prosthetic femoral head separates from the polyethylene liner.

Materials and Methods: Descriptive study of a series of cases, from the period 2019 to 2023, with a diagnosis of intraprosthetic dislocation.

Results: Three clinical cases with intraprosthetic dislocation from our institution are described. All required open reduction and revision total hip arthroplasty. One of them, operated on six months after the event, showed signs of metallosis and wear; the polyethylene liner was not found during the intraoperative period.

Conclusion: In a hip prosthetic dislocation with dual-mobility components, intraprosthetic dislocation should be considered. The reduction is generally open
