Examination of the microstructure of human bone is useful in estimating age at death in forensic science cases. This technique has been tested and is well accepted, however samples of burned bone may complicate analysis because of possible changes in the microstructure occurring during the burning process. In a comparison of fresh and burned ground thin sections taken from midshaft femorae of eight dissecting-room cadavers of known age and sex, this study finds significant shrinkage of microstructural elements through the burning process. These results are compared to previous work on the subject, which found the microstructural elements to increase through the burning process.
在法医案件中，对人骨微观结构的检查有助于估计死亡年龄。这项技术已经经过测试且被广泛接受，然而，由于在燃烧过程中微观结构可能发生变化，烧焦的骨头样本可能会使分析变得复杂。在对八具已知年龄和性别的解剖室尸体的股骨干中段获取的新鲜和烧焦磨片薄切片进行比较时，本研究发现，在燃烧过程中微观结构元素显著收缩。这些结果与之前关于该主题的研究进行了比较，之前的研究发现微观结构元素在燃烧过程中会增加。
