Background: To compare the clinical effects between wrist arthroscopy-assisted open reduction plus internal fixation, using the triangular fibrocartilage complex (TFCC) as an example, and simple open reduction plus internal fixation in the treatment of distal radius fractures (DRFs). The study aims to assess the efficacy of arthroscopic-assisted open reduction and internal fixation in treating distal radius fractures. Methods: The study utilized a retrospective cohort research approach, involving 60 patients treated at Binzhou Medical University Hospital between August 2021 and October 2022. These patients met the specified criteria and underwent two distinct surgical procedures for DRFs. Prior to surgery, thorough communication was established with the patients to elucidate the advantages, risks, and associated costs of wrist arthroscopy, and informed consent was obtained. Subsequent to the surgeries, postoperative follow-up was conducted to evaluate the variances between the two treatment modalities. Postoperative analysis and assessment encompassed the patients' Visual Analogue Scale (VAS) scores, Cooney wrist scores, grip strength of the affected limb (in comparison with the healthy side), wrist range of motion, and the frequency of intraoperative fluoroscopy usage. Results: No surgical complications were observed among all patients. They were followed up for an average duration of (12.1 ± 1.3) months postoperatively, during which all fractures healed successfully. Within the treatment group, arthroscopy detected 14 cases of TFCC tears during the operation, all of which were repaired under a microscope. Conversely, physical examination identified three cases of TFCC injury in the control group, which were treated via incision and suture. At the 3-month postoperative mark, the treatment group exhibited significantly superior comprehensive scores for wrist pain, grip strength, and wrist range of motion compared to the control group (p < 0.05). Cooney's comprehensive wrist joint scoring yielded the following results: treatment group — excellent in 21 cases, good in five cases, and moderate in four cases; control group — excellent in 16 cases, good in nine cases, and moderate in five cases. Conclusion: Wrist arthroscopy-assisted surgery facilitates precise reduction of the articular surface and alleviation of intraarticular congestion. Moreover, it enables evaluation and repair of concurrent intra-articular injuries such as TFCC tears and other tissue injuries, thereby reducing the likelihood of chronic wrist pain. Consequently, this technique should be deemed valuable in clinical practice owing to its outstanding clinical efficacy.
