Actualization of the standard values for the maturation of the iliac bone apophysis by Risser.
The study analysed retrospectively 515 data from 154 patients of german descent with idiopathic scoliosis. The study group included 312 X-rays of 82 female and 203 X-rays of 72 male patients, born between 1970-1985 and within the age of 10 and 20 years at the time of the evaluation. The middle chronological age, the standard deviation, the difference between female and male patients as well as the t-value were calculated for each stage. In addition the intervals with the corresponding t-values were calculated.
The middle chronological age calculated for the stages of Risser shows significant differences. Because of acceleration the ossification begins earlier and finishes later. As assumed, the standard values were different for female and male patients.
The necessity of a new and complete investigation was given because of the acceleration of the maturation and the incomplete existing standard values.
This study contains current standard values for maturation of the iliac bone, which could be applied for analysing the skeletal maturation.
实现里塞尔（Risser）法评估髂骨骨骺成熟度的标准值。
本研究回顾性分析了154例德国裔特发性脊柱侧凸患者的515份数据。研究组包括82例女性患者的312份X线片和72例男性患者的203份X线片，这些患者出生于1970年至1985年之间，评估时年龄在10岁至20岁之间。计算每个阶段的中位年龄、标准差、女性和男性患者之间的差异以及t值。此外，还计算了相应t值的区间。
里塞尔各阶段计算出的中位年龄存在显著差异。由于发育加速，骨化开始得更早且结束得更晚。正如所假设的，女性和男性患者的标准值不同。
由于成熟加速和现有标准值不完整，有必要进行新的全面研究。
本研究包含了当前髂骨成熟度的标准值，可用于分析骨骼成熟情况。
