Abstract
Objectives: In this study, we aimed to compare the clinical and radiological outcomes of patients undergoing arthrodesis and trapeziectomy with ligament reconstruction and tendon interposition (T + LRTI) for thumb carpometacarpal (CMC) osteoarthritis and to investigate whether patient-specific decision-making could offer advantages over LRTI or arthrodesis as a surgical approach.
Patients and methods: Between August 2014 and January 2025, a total of 40 patients who underwent surgical treatment for thumb CMC osteoarthritis were retrospectively analyzed. The patients were divided into two groups as the T + LRTI group (n = 22) and arthrodesis group (n = 18). Clinical outcomes were assessed using the Visual Analog Scale (VAS), Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH), grip strength (kg), and pinch strength (kg) measurements.
Results: Of the patients, 7 were male and 33 were female with a mean age of 62.9±6.5 years in T + LRTI group, 60.1±7.4 years in arthrodesis group (range, 40 to 75 years). Both groups demonstrated significant improvement in VAS and QuickDASH scores postoperatively (p < 0.001). The mean postoperative VAS scores were 2.7±2.0 in the T + LRTI group and 1.9±0.9 in the arthrodesis group (p = 0.267), while QuickDASH scores were 26.4±17.3 and 19.1±3.2, respectively (p = 0.085). No significant differences were observed in grip strength (p = 0.358), palmar pinch (p = 0.104) and key pinch strength (p = 0.097) between the groups. The overall complication rate was 12.5% in both groups, indicating no statistically significant difference (p = 0.642).
Conclusion: Our study results suggest that both T + LRTI and arthrodesis provide effective and comparable pain relief and functional outcomes in the surgical management of thumb CMC osteoarthritis and can be considered reliable surgical options.
