  • Title: Dislocations after use of dual-mobility cups in cementless primary total hip arthroplasty: prospective multicentre series.
    Author: Hwang JH, Kim SM, Oh KJ, Kim Y.
    Journal: Int Orthop; 2018 Apr; 42(4):761-767. PubMed ID: 28986663.
    Abstract:
    BACKGROUND: The purpose of this study was to investigate the incidence of dislocation and specific complications of the dual-mobility cup. METHODS: The arthroplasties involved 167 hips in 165 patients; 51 hips (30.5%) were in men and 116 (69.4%) were in women. The active articulation E1® dual-mobility cup (Biomet, Warsaw, IN, USA) was used, and the surgical approach was posterolateral in 120 hips and anterolateral in 47 hips. RESULTS: Four (2.3%) dislocations were observed. Mean time of dislocation was 30.5 days post-operatively. Three incomplete reductions occurred during closed reduction. When comparing parameters between dislocation and no-dislocation groups, there were no differences in patient and surgical parameters. However, all dislocations occurred in patients with femoral neck fractures and in the posterolateral approach group. CONCLUSION: The incidence of dislocation in total hip arthroplasty (THA) using a dual-mobility cup was acceptable, and cup diameter of the dislocation group was substantially larger than that of no-dislocation group. Based on clinical outcomes of our study, we conclude that the dual-mobility cup is a reliable option in THA, and further studies are necessary.
