Using surgically implanted metal markers, serial radiographs of 17 immature femurs were evaluated for growth of the entire femur and of the distal femoral physis in rabbits 20 to 100 days of age. From these data the rate of longitudinal growth was plotted. The most rapid growth during the study period was from 20 to 40 days. Growth rates reached a plateau at 100 days of age. The increases in length for unit of time were compared for the entire femur and the distal physis. The distal physis was responsible for approximately 65-70% of the femoral growth for the study period. As an internal control of reproducibility of measurement, two means of determining distal femoral growth rates were compared. Their best fit curves proved to be almost identical. The model of evaluation of femoral growth is reproducible and can serve as a control against which variables in growth can be compared.
使用手术植入的金属标记物，对17只20至100日龄幼兔的未成熟股骨进行系列X线片检查，以评估整个股骨和股骨远端骨骺的生长情况。根据这些数据绘制纵向生长速率图。研究期间生长最迅速的阶段是20至40天。生长速率在100日龄时达到平稳状态。对整个股骨和远端骨骺的单位时间长度增加量进行了比较。在研究期间，远端骨骺约占股骨生长的65%-70%。作为测量重复性的内部对照，比较了两种确定股骨远端生长速率的方法。它们的最佳拟合曲线证明几乎相同。股骨生长评估模型具有可重复性，可作为对照，用以比较生长中的变量。
