Objectives/Interrogation: Thumb pain secondary to arthritis at the basal joint of the thumb is a common condition, especially in women, and can be quite disabling. The present study was the first to use and evaluate early outcomes of Moovis prosthesis for arthroplasty of the first CMC in patients with Eaton-Littler stage III osteoarthritis.

Methods: In total, 50 patients were randomised to either Moovis prosthesis (n=23) or Epping-plastic procedure (n=27) and examined between 2014 and 2017. Beside patient characteristics, clinical outcomes concerning functional abilities and pinch strength were obtained preoperatively and at 6 weeks, 3, 6 and 12 months Follow-Up. In addition DASH-Score, Visual analog scale and SF-36 were assessed at the same time points. The mean and standard deviation were analyzed and t-tests and Mann-Whitney U-Tests were conducted to determine significant differences.

Results and Conclusions: Clinical outcomes showed statistical significant differences with higher scores in radial abduction (62.2° vs. 53.3°; p=0.008) 6 weeks postoperatively and in retropulsion of kapandji (2.8 vs. 2.3; p=0.007) 12 months postoperatively among patients with prosthesis compared to those with epping-plastic procedure. Mean DASH-score (p=0.001; p=0.023) and pain (p=0.013; p=0.029) was lower in the prosthesis group 6 weeks and 3 months postoperatively. Regarding quality of life, significant differences were found at 6 weeks, 3 and 6 months postoperatively but diminish after 12 months of operation.

The new carpometacarpal prosthesis Moovis have reliable Outcomes and a low complication rate also compared to the standard procedure.
