对整个骨样本以及标准化骨样本的电特性（电阻、电容、介电常数、介电损耗因数和耗散因数等）的现有数据进行审查表明，纵向阻抗最低，径向阻抗最高。这是骨的各向异性性质的进一步证据。完全水合的骨骼的电特性与干燥和部分湿润的骨骼的电特性显着不同，并且这些特性高度依赖于频率。还回顾了影响电性能的其他变量，例如水分含量、测量原理和方法、温度、浸没液体的pH值和电导率等。描述这些变量对于报告骨电特性的测试结果非常重要；只有这样才能比较不同作者报道的不同骨电特性的数据。未来的研究需要描述年龄、微观结构、矿物质含量和各种疾病过程对骨电特性的影响。这些信息可能会带来关于电特性在骨重塑中的作用的新见解。了解骨骼的电行为对于电刺激设备的设计及其正确使用以获得最大的成骨效果也很重要。
A review of the available data on the electrical properties (resistance, capacitance, dielectric constant, dielectric loss factor, and dissipation factor, etc.) of whole as well as standardized bone specimens suggest that impedance was lowest in the longitudinal direction and highest in the radial direction. This is further evidence of the anisotropic nature of bone. The electrical properties of fully hydrated bone were significantly different from those of dry and partially wet bone and these properties were highly frequency-dependent. Other variables that influence the electrical properties, such as moisture content, principles and methods of measurement, temperature, and pH and conductivity of the immersing fluid, etc., have also been reviewed. Delineation of these variables is important in reporting test results on the electrical properties of bone; only then can the data on different electrical properties of bone reported by various authors be compared. Future research is needed to characterize the effect of age, microstructure, mineral content, and various disease processes on the electrical properties of bone. Such information may lead to new insight on the role of electrical properties on bone remodeling. An understanding of the electrical behavior of bone is also important for the design of electrical stimulation devices and their proper use for maximum osteogenic effect.
