To evaluate the reproducibility of the AO/Asif classification for humeral shaft fractures.
Consecutive radiographs of the arm in both anteroposterior and lateral view from 60 patients with humeral shaft fractures were analyzed. Six observers who were familiar with the AO/Asif classification (three shoulder and elbow surgery specialists and three general orthopedists) were selected to make the analysis, which was done at three different times. The data were subjected to statistical analysis using the kappa coefficient.
The intra and interobserver concordance was statistically significant in all the analyses.
All the evaluators showed concordance between the three evaluations that was considered to be statistically significant. However, the highest values were found among the specialists.
评估AO/Asif肱骨干骨折分类的可重复性。
分析60例肱骨干骨折患者手臂前后位和侧位的连续X线片。选择6名熟悉AO/Asif分类的观察者（3名肩肘外科专家和3名普通骨科医生）进行分析，分析在三个不同时间进行。使用kappa系数对数据进行统计分析。
在所有分析中，观察者内和观察者间的一致性具有统计学意义。
所有评估者在三次评估之间均表现出具有统计学意义的一致性。然而，专家之间的一致性值最高。
