Abstract

Background: Modular dual mobility (MDM) cups are constituted by a cobalt-chromium (CoCr) liner inserted into a standard acetabular shell, allowing for intra-operative decision and supplementary screw fixation of the acetabular component. MDM could face mechanical issues and biological issues, with the associated risk of elevated blood metal ions levels and adverse local tissue reactions (ALTRs).

Materials and methods: A systematic review of the literature on minimum five years outcomes of modular dual mobility in primary total hip arthroplasty (THA) was performed on PubMed, Cochrane, and Google Scholar databases, in adherence with PRISMA guidelines. Risk of bias in each study was assessed through the JBI checklist for case series.

Results: A total of 381 primary THAs with MDM acetabular cup were performed. At minimum five years follow-up, mean revision rate was 2.3% and implant survivorship was 98.2%. No MDM acetabular construct was revised specifically due to liner mechanical failure, neck-rim impingement, or ALTRs. No intraprosthetic dislocation or iliopsoas tendinitis was observed. No cases of THA dislocation were reported. Mean serum metal ion levels were observed to be within laboratory reference ranges. Greater-than-normal values of serum Co were observed in 9.4% of cases, while greater-than-normal values of serum Cr were observed in 1.6% of patients.

Conclusions: The main finding of this systematic review is that modular dual mobility acetabular construct appears to be a safe and effective option for primary THA at minimum five years follow-up. Longer follow-up time is needed in order to investigate modular dual mobility long-term survivorship, revision and complication rates, clinical and radiological outcomes.

期刊介绍： International Orthopaedics, the Official Journal of the Société Internationale de Chirurgie Orthopédique et de Traumatologie (SICOT) , publishes original papers from all over the world. The articles deal with clinical orthopaedic surgery or basic research directly connected with orthopaedic surgery. International Orthopaedics will also link all the members of SICOT by means of an insert that will be concerned with SICOT matters. Finally, it is expected that news and information regarding all aspects of orthopaedic surgery, including meetings, panels, instructional courses, etc. will be brought to the attention of the readers. Manuscripts submitted for publication must contain a statement to the effect that all human studies have been approved by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted. Reports of animal experiments must state that the "Principles of laboratory animal care" (NIH publication No. 85-23, revised 1985) were followed, as well as specific national laws (e.g. the current version of the German Law on the Protection of Animals) where applicable. The editors reserve the right to reject manuscripts that do not comply with the above-mentioned requirements. The author will be held responsible for false statements or for failure to fulfil the above-mentioned requirements.
