DOI: 10.1007/s00264-017-3406-5
Abstract: PurposeThe linear penetration rate (LPR) has been used to estimate volumetric wear ever since metal-on-polyethylene bearings were first introduced. Annual volumetric wear and osteolysis are interrelated. The use of dual mobility cups has increased; however,… read more here.

DOI: 10.1007/s00264-018-3767-4
Abstract: PurposeTotal hip arthroplasty with a dual mobility cup (DMC) is a proposed alternative to the widely performed bipolar hemiarthroplasty (BHA) for treating displaced intracapsular femoral neck fractures (DFNF) in the elderly. However, the comparison between… read more here.

DOI: 10.1016/j.artd.2019.05.001
Abstract: Background The most common indications for revision total hip arthroplasty are instability/dislocation and mechanical loosening. Efforts to address this have included the use of dual mobility (DM) articulations. The aim of this study is to… read more here.

DOI: 10.1016/j.artd.2021.04.017
Abstract: Background The authors performed total hip arthroplasty (THA) using a novel hemispherical dual-mobility (DM) acetabular cup without a protrusive cylindro-spherical rim, intended to reduce risks of iliopsoas impingement without requiring changes to conventional intraoperative positioning… read more here.
