Outcomes of dual mobility arthroplasty in thumb basal joint arthritis: a clinical and radiographic study of one hundred and fifty prostheses with four-years follow-up.
This study evaluated the outcomes of double mobility trapeziometacarpal prostheses for treating osteoarthritis (OA) of the trapeziometacarpal (TMC) joint. A prospective observational analysis was conducted on 150 implants with a maximum follow-up of four years, including a clinical and radiographic assessment and an evaluation of complications. The results indicate a prosthesis survival rate of 97.9% after the first two years post-surgery, calculated using the Kaplan-Meier method. Significant improvements were observed in pain reduction (mean VAS at 3 months post-surgery 2,9 and 1.5 after 6 months), hand grip strength (25.93 kg at 6 months post-surgery), and range of motion (Kapandji score from 8.8 to 9.2, comparing the preoperative mean with the mean after the first postoperative month). The complication rate was low, with only two cases of cup migration and one case of trapezium resorption. Patient satisfaction was high due to the rapid functional recovery and reduced invasiveness compared to traditional techniques. Double-mobility prostheses offer a highly effective treatment for stage II and III TMC OA according to the Eaton-Littler classification, with minimal need for revision surgeries.
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.
