Moseley's Straight Line Graph (M-SLG), which is based on growth data obtained in the 1940s and 1950s, is helpful for the timing of physiodesis. We investigated whether current growth data could improve this graph. We estimated growth curves based on recent data on 182 Dutch children, collected between 1979 and 1994, using repeated measure analysis of variance. In both boys and girls, the mean femur and tibia length had increased, when compared to the data collected by Anderson et al. (1964). Based on our growth data, a new straight line graph (Rotterdam Straight Line Graph; R-SLG) was created. Its value was assessed by comparing the difference between the predicted length of the short (i.e., not operated) limb at maturity with the final limb length. In a group of 34 children who underwent physiodesis up to 10 years ago, the R-SLG gave better prediction of limb length at maturity than the M-SLG did in 22 of 34 cases and equal results were obtained in 5 cases. We conclude that our updated SLG can improve the prediction of final limb length and thus also the timing of physiodesis.
莫斯利直线图（M-SLG）基于20世纪40年代和50年代获得的生长数据，有助于确定骨骺阻滞术的时机。我们研究了当前的生长数据是否能改进该图表。我们使用重复测量方差分析，基于1979年至1994年间收集的182名荷兰儿童的近期数据估计生长曲线。与安德森等人（1964年）收集的数据相比，男孩和女孩的股骨和胫骨平均长度均有所增加。基于我们的生长数据，创建了一个新的直线图（鹿特丹直线图；R-SLG）。通过比较成熟时短肢（即未手术的肢体）的预测长度与最终肢体长度之间的差异来评估其价值。在一组10年前接受过骨骺阻滞术的34名儿童中，在成熟时肢体长度的预测方面，R-SLG在34例中的22例中比M-SLG给出了更好的预测，5例中得到了相同的结果。我们得出结论，我们更新后的直线图可以改进对最终肢体长度的预测，从而也能改进骨骺阻滞术的时机。
