Based on the assumption that bone breaks where it is weakest, so that the fracture surface represents the weakest area locally, a fractographic study was made of a series of accidental and experimental fractures of human long bones. The architecture of the fracture surfaces as a whole, and of the local morphology of the fractured microstructure, was examined. This led to a classification of the fractographic features observed. Several quantitative characteristics of the experimental fracture surfaces were explored, including the number (no), volume fraction (po), and average cross-sectional area (Ao) of the osteons. These parameters were compared with the same data for cross-sections of the bone beneath the fracture surfaces. The results show a short-range fluctuation in the microstructural constitution of the diaphysis close to the fracture surface, with lower values of no, po and Ao at the fracture surface.
基于骨头会在最薄弱处断裂这一假设，即骨折面代表局部最薄弱区域，对一系列人类长骨的意外骨折和实验性骨折进行了断口金相研究。检查了骨折面的整体结构以及骨折微观结构的局部形态。这导致了对所观察到的断口金相特征进行分类。探讨了实验骨折面的几个定量特征，包括骨单位的数量（no）、体积分数（po）和平均横截面积（Ao）。将这些参数与骨折面下方骨横截面的相同数据进行了比较。结果表明，靠近骨折面的骨干微观结构存在短程波动，骨折面处的no、po和Ao值较低。
