Abstract

Objective: To evaluate classification use based on the assessment of agreement in trochanteric fractures between different observers through a simple proposal of bimodal classification.

Methodology: A total of 50 radiographic images of femur trochanteric fractures were selected and classified by 22 evaluators, 10 traumatologists and 12 residents, as STABLE or UNSTABLE. The assessment of reproducibility was done using the kappa statistical index. After the evaluation, the groups were isolated and submitted to the ANOVA test with Bonferroni correction to evaluate the statistical differences between them.

Results: When evaluated by the kappa index, the results of the 50 fractures assessed by the 22 evaluators were k = 0.272. The reproducibility of the classification proposal was considered statistically weak.

Conclusion: Based on this study, it is recommended that the classifications be extensively tested and reach a minimum level of interobserver reproducibility (kappa > 0.8). It is suggested that classifications that do not achieve this result be improved or abandoned. Level of evidence II, Prospective study.

转子骨折：分类可靠吗？

目的：通过简单提出的双峰分型，评价不同观察者对粗隆骨折的一致性，评价分型的应用。方法：选取50张股骨粗隆骨折的x线图像，由22名评估者、10名创伤学家和12名住院医师对其进行稳定或不稳定的分类。用kappa统计指数评价重现性。评价结束后，对各组进行隔离，采用Bonferroni校正的方差分析（ANOVA）检验，评价各组间的统计学差异。结果：用kappa指数评价50例骨折，22名评价者评价的结果k = 0.272。分类建议的可重复性被认为在统计上很弱。结论：基于本研究，建议对分类进行广泛的检验，并达到最低水平的观察者间可重复性（kappa > 0.8）。建议对不能达到这一结果的分类进行改进或放弃。证据等级II，前瞻性研究。
