由OsteoProbe测量的骨材料强度指数(BMSi)与常规材料上的维氏硬度和洛氏(RW)硬度测量显著相关。Vickers和RW测量是根据美国测试和材料协会的标准测试方法进行的，而OsteoProbe测量则遵循已公布的标准化测试方法。BMSi与RW硬度之间的相关系数r=0.93，BMSi与维氏硬度之间的相关系数r=0.94，与RW与维氏硬度之间的相关系数r=0.87相当。在p<；0.01处，BMSi与RW之间的相关性显著，在p<；0.01处，BMSi与维氏硬度之间的相关性显著。这些结果表明，OsteoProbe进行的压痕测量可以被认为是一种可与广泛使用的传统方法相媲美的硬度测量类型，其便携式和窄的设计针对特定的应用。
The bone material strength index (BMSi), as measured by the OsteoProbe, is significantly correlated with Vickers hardness and Rockwell (RW) hardness measurements on conventional materials. The Vickers and RW measurements were carried out according to American Society for Testing and Materials standard test methods, and OsteoProbe measurements followed published standardized testing methods. The correlations between the BMSi and RW hardness, r = 0.93, and between the BMSi and Vickers hardness, r = 0.94, are comparable with the correlation between RW and Vickers hardness, r = 0.87. The correlation between the BMSi and RW is significant at p < 0.01, and the correlation between the BMSi and Vickers hardness is significant at p < 0.01. These results show that the indentation measurement performed by the OsteoProbe may be considered as a type of hardness measurement comparable to widely used conventional methods, with specific applications targeted by its portable and narrow design.
