Indicators of trabecular bone structure along with the apparent Young's modulus may be a predictor of the risk of bone fracture in the elderly. The use of mechanical treatment in the process of obtaining a sample of a structure to determine these indicators causes damage to its surface, leading to defects in the shape and position of the outline. The paper presents the results of studies leading to the demonstration of the influence of these defects on the values of the BV/TV and the apparent Young's modulus. These results justify the necessity to select the theoretical shape of a cylinder from the scanned images in order to define the geometrical shape of a representative sample. The paper presents a method for determining the parameters of this cylinder based on the best-fit cylinder algorithm.
