The investigation of the effect of direct current on the mechanical properties of experimental fractures was conducted by applying 7-10 microA of constant current to the osseous defect of the rabbits' fibulae. The fibulae were tested mechanically with the combined methods of nondestructive technique and breaking-strength measurement. The result was analyzed in relation to the volume of the newly formed callus, which was estimated by roentgenographic appearance and calculation. There is no accurate proof that an electrically stimulated callus is superior in mechanical strength. A more massive callus in a relatively earlier stage suggests that the stimulated callus may have some advantages over the nonstimulated callus.
通过对兔腓骨骨缺损施加7 - 10微安的恒定电流，开展了直流电对实验性骨折力学性能影响的研究。采用无损检测技术和断裂强度测量相结合的方法对腓骨进行力学测试。根据X线表现和计算估计的新形成骨痂体积对结果进行分析。尚无确切证据表明电刺激形成的骨痂在力学强度上更优。在相对较早阶段形成的更大量骨痂表明，受刺激形成的骨痂可能比未受刺激的骨痂具有一些优势。
