Early Intraprosthetic Dislocation of Dual- Mobility Total Hip Arthroplasty Implant Following Attempted Closed Reduction: A Case Report
Introduced in 1974 by Bousquet, the dual-mobility bearing for use in total hip arthroplasty (THA) confers increased jump distance and improved overall stability relative to conventional THA designs [1-3]. The dual-mobility bearing incorporates a relatively small (22-28mm) metal or ceramic femoral head press fit into a larger polyethylene liner which articulates with the acetabular component. Di...
متن کاملEarly Intraprosthetic Dislocation of A Dual Mobility Acetabular Construct
Dislocations represent one of the more common postoperative complications seen after total hip arthroplasty (THA) with estimates ranging from 0.2 to 7% in primary cases and as high as 25% in revision surgeries [1]. In the early 1970s, Giles Bousquet developed a dual mobility (DM) acetabular cup with the goal of reducing dislocation rates. The dual mobility (DM) design consists of two articulati...
متن کاملEarly Intraprosthetic Dislocation of a Dual Mobility Acetabular Construct after Total Hip Arthroplasty
INTRODUCTION The concept of a dual mobility (DM) cup has been in existence for more than 40 years and was initially popularized in Europe. Only recently has it started to garner attention in the United States. Its design, consisting of a small femoral head articulating within a larger polyethylene (PE) insert, which articulates with an outer shell, has found increasing use in patients that are ...
متن کاملEarly intraprosthetic dislocation in dual-mobility implants: a systematic review
BACKGROUND Dual mobility implants are subject to a specific implant-related complication, intraprosthetic dislocation (IPD), in which the polyethylene liner dissociates from the femoral head. For older generation designs, IPD was attributable to late polyethylene wear and subsequent failure of the head capture mechanism. However, early IPDs have been reportedly affecting contemporary designs. ...
متن کاملIntraprosthetic dislocation of a contemporary dual-mobility design used during conversion THA.
Although dual-mobility sockets have been in clinical use for decades in other parts of the world, they recently gained popularity in the United States as an option for primary and revision total hip arthroplasty (THA). Improvements in dual-mobility socket technology include articulation with a metal insert impacted into a metal shell and a femoral head made of highly cross-linked polyethylene. ...
