Abstract
Background: Distal scaphoid resection (DSR) with suspensionplasty using the Mini-TightRope™ has not previously been reported for isolated scaphotrapeziotrapezoid (STT) osteoarthritis. The aim of this study is to report outcomes of DSR using the Mini-TightRope™ for STT arthritis. Methods: We retrospectively evaluated four female patients (four wrists; mean age: 71 years) who underwent this procedure between 2018 and 2020, with a mean follow-up of 72 months. Clinical and radiographic outcomes, including pain (visual analogue scale [VAS]), grip strength, DASH-JSSH scores, trapezial subsidence and dorsal intercalated segment instability (DISI), were assessed. Results: The mean VAS improved from 6.0 to 1.0 and the DASH-JSSH score from 59.0 to 19.5. Grip strength was 13.9 kg (97% of the contralateral side), and the trapezial height was well maintained with minimal subsidence. DISI developed in all patients (mean radiolunate angle: 9.3°-32.7°) but remained asymptomatic, and no complications or revisions occurred. Conclusions: This simple, tissue-preserving technique provided satisfactory outcomes for isolated STT osteoarthritis. Level of Evidence: Level IV (Therapeutic).
