[Formulation on the growth of the human tibia based on Gindhart's data (1976)]

Length data for the tibia as gained at the Fels Research Institute for the Study of Human Development and published by Gindhart (1976) are used for mathematical formulation following the method set up by the author for the representation of human length growth and recently applied to the radius development. The data for the tibia leave smaller room for the validity of the short term power function characteristic for younger age. Difficulties were encountered but overcome for the growth function proper (Sager 1981 a), whilst some uncertainties remain for the growth spurt of the female due to irregularities in the basic material.
