Abstract

Introduction Trapeziectomy and suture-button suspensionplasty (SBS) are a novel option to treat end-stage trapeziometacarpal (TMC) osteoarthritis. Our purpose is to evaluate our outcomes with this technique and in this setting, with a minimum of 18 months of follow-up.

Materials and Methods Twenty-eight patients were included, operated between 2016 and 2018. We recorded demographic data, preoperative Eaton stage, follow-up and operative times. The patients completed the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) questionnaire and tip pinch, key pinch, and grip strength were measured. First metacarpal subsidence was calculated, and postoperative complications were documented.

Results The average follow-up was 34 months. The mean QuickDASH was 32 at the final follow-up. The average strength results were 20 kg for grip, 3.6 kg for tip pinch, and 4.2 kg for key pinch. The rate of first ray subsidence was 10.7%. We encountered three complications: a hardware intolerance, a second metacarpal fracture, and a suture rupture. There was one reoperation to remove an implant.

Conclusion Trapeziectomy and SBS functional results are similar to other techniques, with less subsidence of the first ray and allowing for early mobilization and fast recovery. This procedure is a safe and promising option in the treatment of TMC osteoarthritis, with good medium-term outcomes.
