Background: The purpose of this study was to analyze the clinical efficacy of allogeneic tendon ball tamponade with the proximal joint surface of trapezium preservation for the treatment of patients with first carpometacarpal arthritis in patients in Eaton stage Ⅱ and Ⅲ.Methods: Data of 16 patients with first carpometacarpal arthritis who were treated with allogeneic tendon ball tamponade with the proximal joint surface of trapezium preservation from April 2016 to June 2021 were retrospectively analyzed. The subsidence rate of the first carpometacarpal joint was evaluated based on the height of the joint space and its index according to three-dimensional computed tomography (3D-CT). Visual analogue scale (VAS) score, disabilities of the arm, shoulder, and hand (DASH) score, grip strength and pinch force pre- and post-operatively were analyzed. The data were analyzed by t-test or one-way analysis of variance (ANOVA) followed by Tukey’s post hoc test for multiple comparisons. Results: All participants were followed up for at least 8 months. After the surgery, the VAS and DASH scores were significantly lower than those before surgery. The pinch strength and grip strength significantly increased. No significant difference was found in the carpometacarpal height index at the final follow-up, indicating that the first metacarpal had no obvious collapse after surgery. Conclusion: Allogeneic tendon tamponade with the proximal joint surface of trapezium preservation is effective for the first carpometacarpal joint arthritis in patients with Eaton stages Ⅱ and Ⅲ. The therapeutic effect of this modified operation was satisfactory for alleviating pain and reducing the collapse rate of the first metacarpal. |
