Abstract
Dual-mobility bearing total hip arthroplasty offers several advantages over traditional prosthesis designs in the treatment of degenerative hip disease. Over decades of use, they have shown proven benefits in both durability and stability. However, despite their practical and theoretical advantages, they present a unique mode of failure not seen with other implants. In this report, the authors present two patients who sustained intraprosthetic dislocation of their dual-mobility total hip arthroplasty components during closed reduction of a hip dislocation.
