The Moovis® implant for trapeziometacarpal osteoarthritis: results after 2 to 6 years

Abstract

In this retrospective study we reviewed the outcomes of 46 trapeziometacarpal joint replacements with the Moovis® prosthesis in 46 patients with painful osteoarthritis. The dual mobility design of this prosthesis aims to reduce prosthetic dislocation and subsidence. At follow-up 2 to 6 years (mean 5 years) after operation, pain was reduced from 6 to 0 on a visual analogue scale from 0 to 10. The scores of the Quick Disabilities of the Arm, Shoulder and Hand questionnaire improved significantly. Thumb motion and grip and pinch strength did not differ significantly from the contralateral hand. There were no radiographical signs of implant subsidence or loosening. No implant required revision. Forty-five patients rated the result as excellent or good. We conclude the Moovis® is a reliable and effective implant at short- to mid-term follow-up. Level of evidence: IV

Thumb CMCJ prosthetic total joint replacement: a systematic review

“…Strength measurement was reported in 36 studies. 4 , 6 , 7 , 9 , 10 , 12 , 14 , 16 , 19 – 27 , 29 , 32 – 34 , 36 – 38 , 40 – 42 , 44 , 46 , 48 – 50 , 53 – 56 Comparable pre and post-operative values were reported in 16 studies. 7 , 9 , 10 , 14 , 20 , 23 , 27 , 29 , 33 , 40 , 41 , 44 , 48 , 49 , 53 , 56 Strength measurements of grip, key pinch and tip pinch were included.…”

“…Quantifiable range of motion measurements/scores were reported in 38 studies. 4 , 5 , 9 , 10 , 12 – 17 , 19 , 21 , 23 – 27 , 30 , 32 – 34 , 36 – 40 , 42 – 53 Comparable pre and post-operative values were reported in 13 studies. 10 , 13 , 19 , 23 , 24 , 27 , 33 , 34 , 36 , 39 , 48 , 50 , 53 Objective range of motion assessment included the Kapandji Opposition score, degrees of thumb abduction (either radial or palmar), and the Buck-Gramcko score, which is a measure of various movements.…”

“… 5 – 38 Comparable pre and post-operative values were reported in 12 studies. 7 , 9 , 10 , 13 , 16 , 17 , 19 , 23 , 27 , 29 , 32 , 33 The most commonly used patient-reported outcome measures (PROMs) were the Disabilities of the Arm Shoulder and Hand measure (DASH) or quick DASH which are general upper extremity scoring systems. Other measures included the Michigan Hand Questionnaire (MHQ) which is more specific to hand complaints, the Nelson score, which is specific to thumb outcomes, the Patient Related Wrist Evaluation (PRWE) score which is a wrist-specific measure, and the Sollerman score which is a measure of hand function.…”

“… 4 – 7 , 9 – 11 , 13 , 15 – 17 , 19 – 24 , 26 , 27 , 29 – 35 , 38 – 41 Comparable pre and post-operative values were reported in two studies for satisfaction, 16 , 39 and 16 studies for pain. 7 , 9 , 10 , 13 , 16 , 17 , 19 , 20 , 23 , 27 , 29 , 32 – 34 , 39 , 41 Subjective satisfaction and pain scores using the visual analogue scale (VAS) system were collected to provide a comparative outcome measure. A number of studies reported pain and satisfaction as a percentage of patients ‘satisfied’ or ‘pain free’, but these measures were not felt to be reliable and useful for comparative analysis.…”

The mechanical fixation of a cementless conical cup in cortical versus cancellous trapezial bone: an experimental study

“…High revision rates have been described for many trapeziometacarpal (TMC) implants during the last decades (Hansen, 2021). Cup failure has frequently been the problem, but introduction of newer cementless cup designs has improved the clinical outcomes as well as medium- to long-term implant survival (Dremstrup et al., 2021; Martins et al., 2020; Tchurukdichian et al., 2020).…”
