“…This result is found to be in line with many authors reporting very low rates of infection using DMC. [34][35][36] In summary, none of the included aetiologies/risk factors showed statistical differences when DMC is used. However, the impact of having > 1 risk factor, such as those young patients with osteonecrosis, is unknown.…”

Primary total hip arthroplasty: mid-term outcomes of dual-mobility cups in patients at high risk of dislocation

et al. 2019

Introduction: Dual-mobility cups (DMC) are currently used in patients having risk factors of instability. Most of the studies report the use of DMC in patients having a single high-risk variable. The aim of the study was to analyse a continuous series of patients treated with primary total hip arthroplasty (THA) and DMC with different high risk for dislocation. Methods: This is a retrospective study analysing the outcomes of primary THA with DMC in patients at high-risk of dislocation. The sample consisted of 215 patients having 1 of 3 aetiologies or risk factors: (1) young subjects (<55 years); (2) osteonecrosis of the femoral head (ONFH); and (3) femoral neck fracture (FNF). Results: With a mean follow-up duration of 70 ± 24.7 months, the findings showed the following: 2 patients had dislocated their hip following motor vehicle accidents; 1 patient had a traumatic femoral peri-prosthetic fracture; and 1 patient had an acute infection. No intra-prosthetic dislocation or aseptic loosening were encountered. No radiolucent lines were observed on the acetabular side. The mean modified Hip Harris Score was 96.6 ± 7.4%. Out of 186 patients, 170 (90.1%) would label their operated hip as a “forgotten hip”. 78 out of the 84 patients (92.8%) who used to practice oriental sitting and/or ablution for prayers were able to return to their usual daily activities of extreme hip position and 74 out of the 84 patients (88%) described their operated hip as “a forgotten hip”. No correlation was found between any of the studied variables. Discussion: The findings of this series of patients at high risk of dislocation showed excellent clinical and radiological results with very few complications. The use of DMC seems to counteract the impact of some aetiologies/risk factors that could lead to higher instability. Most patients practising extreme hip positions resumed their usual practices.

“…The use of cemented dual mobility cups may be an option in case of severe osteoporosis, especially in elderly patients, in whom there is a potential concern regarding the quality of fixation. At intermediate follow-up, cemented implants have shown similar results to those of contemporary press-fit DMCs 27,28 . The wide use of dual mobility cups in the treatment of displaced femoral neck fractures has highlighted a low dislocation rate in many prospective studies, regardless of the variable experience of operators adopting this approach.…”

Background: Instability is a common complication following total hip arthroplasty (THA). The dual mobility cup (DMC) allows a reduction in the dislocation rate. The goal of this systematic review was to clarify the different uses and outcomes according to the indications of the cemented DMC (C-DMC). Methods: A systematic review was performed using the keywords “Cemented Dual Mobility Cup” or “Cemented Tripolar Cup” without a publication year limit. Of the 465 studies identified, only 56 were eligible for the study. Results: The overall number of C-DMC was 3452 in 3426 patients. The mean follow-up was 45.9 months (range 12–98.4). In most of the cases (74.5%) C-DMC was used in a revision setting. In 57.5% DMC was cemented directly into the bone, in 39.6% into an acetabular reinforcement and in 3.2% into a pre-existing cup. The overall dislocation rate was 2.9%. The most frequent postoperative complications were periprosthetic infections (2%); aseptic loosening (1.1%) and mechanical failure (0.5%). The overall revision rate was 4.4%. The average survival rate of C-DMC at the last follow-up was 93.5%. Conclusions: C-DMC represents an effective treatment option to limit the risk of dislocations and complications for both primary and revision surgery. C-DMC has good clinical outcomes and a low complication rate.
