The aim of the paper is to draw attention to exponential viscoelastic creep measures for the description of viscoelastic deformation of the bone tissue. The proposed two-parametric exponential time function provides a real modelling of medium-time deformation processes and brings advantage in interpretation and generalisation of experimental results. This is documented by empirical data taken from literature. The two parameters of the creep measure characterize the capability of a bone tissue to react quickly and viscoelastically to the changes of load and the rate of viscoelastic deformation increment. The models enables a simple time-age superposition and medium-term or long-term predictions.
