A clinical investigation has been carried out into the effect of small electrical currents on the healing of mandibular fractures. Electrical stimulation of fracture healing was carried out in 40 patients with a direct current of 10 or 20 microamperes delivered through a platinum electrode. An equal number of patients with similar fractures were selected as controls. Rate of repair was assessed by measuring the mobility of the fracture. Serum phosphatase and calcium were regularly measured at intervals in both groups after reduction and suggested that alkaline phosphatase activity increased in the stimulated group. The repair process was enhanced in the electrically stimulated fractures compared to the controls in the first 10-14 days after reduction.
已对小电流对下颌骨骨折愈合的影响进行了一项临床研究。通过铂电极对40例患者施加10或20微安的直流电，以电刺激骨折愈合。选择同等数量的类似骨折患者作为对照。通过测量骨折的活动度来评估修复率。复位后定期对两组患者的血清磷酸酶和钙进行测量，结果显示刺激组碱性磷酸酶活性增加。与对照组相比，复位后的前10 - 14天，电刺激骨折的修复过程得到了增强。
