The aims of the present study were to assess the reliability of clavicular tilt angle measurement using goniometric and photographic measurements and to test the validity of the measurement by comparing the results with radiographic findings (gold standard). Clavicular tilt angles were measured in 18 healthy subjects (36 clavicles) using goniometric, photographic, and radiographic measurement. Repeated measurements using goniometric and photographic measurements were made in two test sessions conducted on different days by two examiners to assess inter-rater and intra-rater reliability of the two methods. Radiographic measurement was taken once, and the correlation between the radiographic findings and those of the indirect methods was calculated to test the validity of the goniometric and photographic measurement of clavicular tilt angle. No significant difference in clavicular tilt angle measurement was found between test sessions. The reliability of goniometric measurement (inter-rater intraclass correlation coefficients (ICC) = 0.85 (95% CI = 0.72-0.92) - 0.87 (95% CI = 0.77-0.87); intra-rater ICC = 0.80 (95% CI = 0.64-0.89)) and photographic measurement (inter-rater ICC = 0.89 (95% CI = 0.80-0.94) - 0.95 (95% CI = 0.91-0.98); intra-rater ICC = 0.84 (95% CI = 0.71-0.92) - 0.84 (95% CI = 0.69-0.91)) were excellent. The goniometric and photographic measurements of clavicular tilt angle were highly correlated with the radiographic findings (r = 0.83, 0.78, respectively). Goniometric and photographic measurements of clavicular tilt angle obtained by raters in this study may be considered reliable, and data obtained using the goniometric and photographic measurements are representative of radiographic findings of clavicular tilt angle.
本研究的目的是评估使用测角法和摄影测量法测量锁骨倾斜角度的可靠性，并通过将结果与放射学检查结果（金标准）进行比较来检验测量的有效性。对18名健康受试者（36根锁骨）进行了锁骨倾斜角度的测量，采用测角法、摄影测量法和放射学测量法。由两名检查者在不同日期进行的两次测试中，使用测角法和摄影测量法进行重复测量，以评估两种方法的评分者间和评分者内可靠性。放射学测量仅进行一次，计算放射学检查结果与间接测量方法结果之间的相关性，以检验锁骨倾斜角度测角法和摄影测量法的有效性。两次测试之间锁骨倾斜角度测量无显著差异。测角法测量的可靠性（评分者间组内相关系数（ICC）=0.85（95%CI=0.72-0.92）-0.87（95%CI=0.77-0.87）；评分者内ICC=0.80（95%CI=0.64-0.89））和摄影测量法的可靠性（评分者间ICC=0.89（95%CI=0.80-0.94）-0.95（95%CI=0.91-0.98）；评分者内ICC=0.84（95%CI=0.71-0.92）-0.84（95%CI=0.69-0.91））都非常好。锁骨倾斜角度的测角法和摄影测量法与放射学检查结果高度相关（分别为r=0.83、0.78）。本研究中检查者获得的锁骨倾斜角度的测角法和摄影测量结果可认为是可靠的，并且使用测角法和摄影测量法获得的数据代表了锁骨倾斜角度的放射学检查结果。
