The superiority of the open reduction and internal fixation (ORIF) and external fixation remains uncertain owing to the limited sample size involved in the literature. This retrospective cohort research was implemented for the comparison of the efficiency of ORIF and external fixation utilizing the locked volar plating in treating the intra-articular fractures of distal radius. We hypothesized that compared with the external fixation, ORIF can improve the functional scores and reduce complications.
We conducted a retrospective and single-center cohort trial that was approved by institutional review committee of Gansu Provincial Hospital. From June 2016 to July 2018, in our experiment, 178 patients with intra-articular fractures of the distal radius were recruited. Inclusion criteria in this cohort study were designed as follows: the age of patients is between 18 and 65 years, the patients with American Society of Anesthesiologists level I-III, and with the AO-type C3 or C2 fractures of distal radius confirmed by computed tomography scans, the patients with radiographic clinical follow-up for 1 year or >1 year. The patients participating in the trial would be divided into 2 groups: the patients treated via the external fixation and the patients treated by the ORIF utilizing volar plate. The main functional results were the grip strength and the range of motion of wrist. Radiographic measurement and complications were also evaluated in our study.
This study protocol will guide and clarify our assignments, and the final outcomes and conclusion will further enrich the clinical knowledge in the literature.

由于文献中涉及的样本量有限，切开复位内固定（ORIF）和外固定的优越性仍不确定。本回顾性队列研究旨在比较使用锁定掌侧钢板治疗桡骨远端关节内骨折时 ORIF 和外固定的效果。我们假设与外固定相比，ORIF 可以提高功能评分并减少并发症。
我们进行了一项回顾性的单中心队列研究，该研究得到了甘肃省医院机构审查委员会的批准。在我们的实验中，从 2016 年 6 月至 2018 年 7 月，共招募了 178 例桡骨远端关节内骨折患者。本队列研究的纳入标准设计如下：患者年龄在 18 至 65 岁之间，美国麻醉医师学会分级 I-III 级，CT 扫描证实为桡骨远端 AO 型 C3 或 C2 骨折，影像学临床随访 1 年或以上。参与试验的患者将分为两组：外固定治疗组和掌侧钢板内固定治疗组。主要的功能结果是握力和腕关节活动范围。我们还评估了影像学测量和并发症。
本研究方案将指导和阐明我们的任务，最终结果和结论将进一步丰富文献中的临床知识。
