Abstract

Background: The Arbeitsgemeinschaft für Osteosynthesefragen (AO) and the Orthopaedic Trauma Association (OTA) classification system for diaphyseal fracture has been recently revised to refine and enhance the accuracy of fracture categorization. This study aimed to investigate the interobserver reliability of the new AO/OTA classification and to compare it with the older version in femoral shaft fractures.

Methods: We retrospectively analyzed 139 patients (mean age, 43.8 ± 19.5 years; 92 men and 47 women) with femoral shaft fractures who were treated from 2003 to 2017. Four well-trained observers independently classified each fracture following the previous and revised AO/OTA classification system. We calculated the Fleiss kappa for the interobserver reliability.

Results: The previous classification showed the kappa value of 0.580 (95% confidence interval [CI], 0.547-0.613), and the revised version showed 0.528 (95% CI, 0.504-0.552). Both the old and the revised versions showed moderate reliability.

Conclusions: Our study highlights the moderate interobserver reliability of both the previous and new AO/OTA classification systems for diaphyseal femur fractures. These findings emphasize the importance of standardized systems in clinical decision-making and underscore the need for ongoing education and collaboration to enhance fracture classification.

2018年修订版AO/OTA股骨柄骨折分类的可靠性。

背景：最近，德国骨科协会（AO）和创伤骨科协会（OTA）对骨骺骨折分类系统进行了修订，以完善和提高骨折分类的准确性。本研究旨在调查新版 AO/OTA 分类法的观察者间可靠性，并将其与旧版股骨干骨折分类法进行比较：我们回顾性分析了 2003 年至 2017 年期间接受治疗的 139 例股骨柄骨折患者（平均年龄为 43.8 ± 19.5 岁；男性 92 例，女性 47 例）。四名训练有素的观察员按照之前和修订后的 AO/OTA 分类系统对每例骨折进行了独立分类。我们计算了观察者间可靠性的弗莱斯卡帕值：旧版分类法的卡帕值为 0.580（95% 置信区间 [CI]，0.547-0.613），修订版的卡帕值为 0.528（95% 置信区间 [CI]，0.504-0.552）。旧版本和修订版本均显示出中等程度的可靠性：我们的研究强调了旧版和新版AO/OTA股骨骺骨折分类系统在观察者之间的中等可信度。这些发现强调了标准化系统在临床决策中的重要性，并强调了持续教育和合作以加强骨折分类的必要性。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
