Outcomes of dual-mobility trapeziometacarpal arthroplasties: a systematic review

This systematic review reports the clinical, patient-reported, radiographic outcomes, complications and survivorship of dual-mobility trapeziometacarpal (TMC) joint arthroplasties including the MAÏA®, Moovis® and Touch® prostheses. Thirteen studies were included and outcomes reported for 1421 such arthroplasties. Overall, improvements in strength, range of motion, pain, function and satisfaction were demonstrated with a complication incidence of 13%. The risk of dislocation was 0.6%. The follow-up period was not long enough to draw conclusions about the long-term survival of the implants. Also, due to the low quality of the evidence, it was not possible to conclude that dual-mobility TMC arthroplasty was superior to trapeziectomy. This review highlights the need for Level I evidence with adequate long-term follow-up for TMC joint arthroplasty.
