Ilisarov's idea that electrical phenomena could contribute to the efficacy of the ring fixation apparatus prompted us to carry out this preliminary investigation. Patients with lower leg fractures and a four-ring fixation apparatus were selected; the electrical potentials were measured over non-fractured and fractured bones. Patients who could not be studied in the Faraday box were subjected to great disturbances, caused by mains voltage and a neighbouring transmitter; in these cases no objective results could be obtained. Only measurements in the Faraday box yielded reproducible results. The results demonstrate that there is generally a difference in electrical potential among the four rings in patients fitted with an Ilisarov apparatus. Furthermore, weight-bearing on the fixator-bone system causes changes in the electrical potential among the rings.
伊里扎罗夫关于电现象可能有助于环形固定装置疗效的观点促使我们进行了这项初步研究。我们选择了小腿骨折且使用四环固定装置的患者；在未骨折和骨折的骨头上测量电位。那些无法在法拉第箱中进行研究的患者受到市电电压和附近发射机造成的极大干扰；在这些情况下无法获得客观结果。只有在法拉第箱中的测量产生了可重复的结果。结果表明，安装伊里扎罗夫装置的患者中，四个环之间的电位通常存在差异。此外，固定器 - 骨系统上的负重会导致环之间的电位发生变化。
