Abstract

Introduction Unlike arthrodesis, total wrist arthroplasty enables the preservation of a functional range of motion in patients operated on for osteoarthritis. The evolution of the implants made it possible to reach a higher success rate, reducing complications such as the loosening of components. The present study aims to demonstrate the functional results and complication rates in a series of cases operated on with the Motec (Swemac Orthopaedics AB, Linköping, Sweden) implant by a single surgeon.

Materials and Methods A retrospective study with 14 patients who underwent total wrist arthroplasty with the Motec system between 2017 and 2022, who were evaluated pre- and postoperatively using the Mayo Wrist Score and the Visual Analog Scale (VAS). The medical records were reviewed in June 2022, and the statistical analysis with the paired t-test considered values of p < 0.05 statistically significant.

Results In total, 13 men and 1 woman, with a mean age of 64.8 (standard deviation [SD] = 7.5) years, underwent surgery, and the mean follow-up was of 25.1 (SD = 10.9) months. The mean preoperative Mayo Wrist Score was of 23.2 (SD = 8.9) points, and postoperatively, it was of 82.8 (SD = 7) points, while the mean preoperative VAS score was of 7.6 (SD = 1.1) points, and, postoperatively, it was of 1 (SD = 1.2) point. The differences regarding the pre- and postoperative results of the Mayo Wrist Score and the VAS were statistically significant (p < 0.001).

Conclusion As demonstrated in the present series, the improvements in terms of function and pain were significant, there were no major complications in the period evaluated, and the prosthesis was successfully replaced failed partial arthrodesis. Patients should be followed up for longer periods, but with the certainty that, in case of failure, a total wrist arthrodesis can still be performed.
