青少年异常学脊椎病 (AIS) 的Lenke分类在受控环境中显示出良好的可靠性,但在临床实践中有所不同. 诸如观察者经验和成像方法等因素会影响协议,特别是在角曲线上.
科学领域:
- 整形外科 整形外科 整形外科
- 脊柱外科手术 脊柱外科手术
- 放射学 放射学是一门学科.
背景情况:
- 伦克分类对于青少年异常学脊椎病 (AIS) 的手术规划至关重要.
- 之前的研究报告了高可重现性,但最近的证据表明可变性,特别是在腰部和腰部修饰器.
- 了解可靠性是优化AIS治疗策略的关键.
研究的目的:
- 系统地评估Lenke分类对AIS的观察者间和观察者内部可靠性.
- 确定影响伦克分类协议的方法因素.
- 为改善分类一致性提供基于证据的建议.
主要方法:
- 一个系统的审查和元分析,遵循PRISMA指南.
- 搜索了五个主要的数据库 (PubMed,Embase,Cochrane CENTRAL,Scopus,Web of Science) 截至2025年8月.
- 提取了观察者特征,成像,测量方法和可靠性指数 (κ,ICC) 的数据;使用QAREL评估了研究质量.
主要成果:
- 包括11项涉及528张X射线图的研究.
- 观察者之间的可靠性平均为 κ=0.76 (腰部 κ=0.75,腰部 κ=0.79);观察者内部的可靠性更高 (κ≈0.82).
- 通过预先测量的放射图,经验丰富的观察员,计算机辅助和更短的间隔来提高可靠性;腰部修饰器是强大的,而斜腰修饰器显示出较低的可重现性.
结论:
- 伦克分类在受控条件下显示出良好的可靠性,但在常规临床实践中不那么一致.
- 方法学因素显著影响协议,需要仔细解释报告的可靠性.
- 建议采用标准化协议,透明报告和数字工具,以提高Lenke分类的可复制性.

Null and Alternative Hypotheses
The null hypothesis, denoted by H0 is a statement of no difference between the variables—they are not related. This can often be considered the status quo. As a result if you cannot accept the null, it requires some action.
The alternative hypothesis, denoted by H1 or Ha, is a claim about the...
