This study analyzed the accuracy of Risser sign staging on posteroanterior radiographs.
To correlate the Risser sign on a posteroanterior radiograph with that on an anteroposterior radiograph.
On the posteroanterior view of the spine, the full length of iliac apophysis is difficult to interpret. No report has assessed the relation of these findings.
The staging of the Risser sign was examined in 89 girls. In 52 subjects, the stage of the Risser sign was identical on both views, whereas in 37 (42%) the interpretations were different.
On evaluation of the iliac apophysis using a skeletal specimen, the posteroanterior views produced a distorted image of the iliac apophysis, and the medial and lateral aspects of the apophysis were superimposed over the ilium.
As a result of these findings and the fact that the Risser staging was developed for the anteroposterior radiograph, the appearance of the iliac apophysis on the posteroanterior radiograph cannot be used as a reliable indicator of skeletal maturity.
本研究分析了后前位X线片上Risser征分期的准确性。
将后前位X线片上的Risser征与前后位X线片上的Risser征进行关联。
在脊柱的后前位视图上，髂骨骨骺的全长难以解读。尚无报告评估这些发现之间的关系。
对89名女孩的Risser征分期进行了检查。在52名受试者中，两种视图上的Risser征分期相同，而在37名（42%）受试者中，解读结果不同。
使用骨骼标本对髂骨骨骺进行评估时，后前位视图产生了髂骨骨骺的扭曲图像，骨骺的内侧和外侧部分叠加在髂骨上。
基于这些发现以及Risser分期是为前后位X线片而制定的这一事实，后前位X线片上髂骨骨骺的表现不能用作骨骼成熟度的可靠指标。
