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.

Raynaud’s syndrome (RS), also referred to as Raynaud’s phenomenon, is a vasospastic disorder causing episodic color changes in extremities upon exposure to cold or stress. These manifestations, either primary Raynaud’s phenomenon (PRP) or associated with connective tissue diseases like systemic sclerosis (SSc) as secondary Raynaud’s phenomenon (SRP), affect the quality of life. Current treatments range from calcium channel blockers to innovative surgical interventions, with evolving efficacy and safety profiles. In this retrospective study, patients diagnosed with RS were selected based on complete medical records, ensuring homogeneity between groups. Surgeries involved microscopic excision of sympathetic nerve fibers and stripping of the digital artery’s adventitia. Postoperative care included antibiotics, analgesia, oral nifedipine, and heat therapies. Evaluation metrics such as the VAS pain score and RCS score were collected bi-weekly. Data analysis was conducted using SPSS 26.0, with significance set at p < 0.05. In total, 15 patients formed the experimental group, with five presenting fingertip soft tissue necrosis and ten showing RS symptoms. Comparative analysis of demographic data between experimental and control groups, both containing 15 participants, demonstrated no significant age and gender difference. However, the “Mean Duration of RP attack” in the experimental group was notably shorter (9.47 min ± 0.31) than the control group (19.33 min ± 1.79). The RS Severity Score also indicated milder severity for the experimental cohort (score: 8.55) compared to the control (score: 11.23). Postoperative assessments at 2, 4, and 6 weeks revealed improved VAS pain scores, RCS scores, and other measures for the experimental group, showing significant differences (p < 0.05). One distinctive case showcased a variation in the common digital nerve and artery course in an RS patient. Our retrospective analysis on RS patients indicates that microsurgical techniques are safe and effective in the short term. As surgical practices lean towards minimally invasive methods, our data supports this shift. However, extensive, prospective studies are essential for conclusive insights.

桡骨远端骨折定义通常是指桡骨远端2.0～3.0 cm以内发生的骨折,多为闭合性骨折,该类型骨折在临床上较普遍.桡骨远端骨折(Distal radial fracture,DRF)约占成人所有骨折的15％.骨折的治疗与并发症相关,并发症发生率高达31％[1-2].根据骨折分类、患者的需求、功能需求,治疗方法会有所不同,包括非手术治疗如石膏固定和手术治疗如切开复位内固定[3].在过去的二十年里,关于腕关节损伤手术中关节镜辅助的文献有所增加.文献涉及腕关节镜的有两个方面:累及关节面的DRF术中关节面复位和急性腕关节韧带损伤的治疗[4].关节镜辅助治疗腕关节韧带损伤的益处似乎得到了积极的共识[5].未能成功复位DRF导致的关节内骨折可导致持续疼痛、关节活动受限或创伤性关节炎[6].

目的 比较Nice结辅助复位技术(Nice结固定)与传统复位技术(螺钉固定)在移位粉碎性外踝骨折中的疗效.方法 回顾性分析105例成人外踝粉碎性骨折(Danis-Weber分型C型)患者资料,根据不同治疗方式分为Nice结组(Nice结辅助复位技术,n=53)与传统组(传统复位技术,n=52).记录并比较2组患者手术时间、术中失血量、骨折愈合时间、术后第2天视觉模拟评分法(VAS)评分、末次随访时踝关节美国足踝骨科学会(AOFAS)评分和术后并发症(内固定失效、感染、骨块移位和骨不连).结果 105例患者均顺利完成手术,随访时间为6～15个月,平均(10.7±3.5)个月.Nice结组手术时间、骨折愈合时间短于传统组,术中出血量少于传统组,差异有统计学意义(P＜0.05);2组术后第2天VAS评分和末次随访踝关节AOFAS评分比较,差异无统计学意义(P＞0.05).Nice结组无术后并发症发生,传统组发生3例骨折块移位.结论Nice结辅助复位技术治疗移位粉碎性外踝骨折的效果优于传统螺钉复位技术,其操作简便,手术时间短,术中出血量少,术后效果较好.
