ABSTRACT
Objective: This study aims to compare the clinical efficacy of two surgical methods, miniaturized anchor nail repair and transosseous tunnel repair, in treating type IB triangular fibrocartilage complex (TFCC) injuries, highlighting the importance of this comparison in optimizing surgical approaches. Methods: We retrospectively analyzed 91 patients with type IB TFCC injuries, treated from June 2020 to January 2022. Group A (43 patients) underwent miniaturized anchor nail repair, and Group B (48 patients) underwent transosseous tunnel repair, both under wrist arthroscopy. Follow-up for 12 months post-surgery included assessments of efficacy, Mayo wrist function score, range of motion, VAS score for ulnar wrist pain, grip strength, DASH score, PRWE, and postoperative complications, along with flow cytometry and lymphocyte immune subset assays. Results: Both groups showed significant improvements in wrist function, grip strength, and range of motion post-surgery, with reduced pain and disability scores. No significant differences in outcomes were observed between the groups. Conclusion: Both miniaturized anchor nail and transosseous tunnel repairs under wrist arthroscopy are effective in improving wrist function and alleviating symptoms in type IB TFCC injuries, with comparable clinical efficacy. These findings could significantly influence surgical practices and future research in TFCC injury management.
