Abstract
The bending of the tibiae of dogs and rabbitsin vivo was studied. A new physical method (margin of errors less than 1%) which gives readily reproducible values of bone stability is reported. The results of bending stiffness, measuredin vivo andin vitro, were nearly identical only if the extremities were slim. If thick, soft parts in the measuring area were present, different loading values followed the same bending. A formula to correct the influence of the soft parts (skin, muscles and tendons) was proposed. The true bending stiffness was determined with the aid of thein vivo values without having to measure the exposed bone afterwards. Comparisons of measurements showed that the values found with the formula reflected the true bending stiffness in a range of errors between 0.3 and 10.5%. A load of 4700±710 g gave a true bending stiffness of 0.1 mm and of a bone area of 1.0 cm2.
