Fifty-three ununited fractures with a median time since injury of 28 months were treated by electrical stimulation using pulsing electromagnetic fields. Union was achieved in 38 cases (71.7 per cent) in a median time of six months. For ununited fractures of the tibia the success rate was higher at 86.7 per cent. Previous or active sepsis, the presence of plates or nails, the age of the patient or the time since the injury did not affect the results. Analysis of the failures suggests that inadequate immobilisation, a fracture gap of more than five millimetres or the presence of a screw in the fracture gap was responsible. In four patients no cause of failure could be determined.
53例骨折不愈合患者，自受伤至治疗的中位时间为28个月，采用脉冲电磁场进行电刺激治疗。38例（71.7%）患者实现了骨折愈合，中位愈合时间为6个月。胫骨骨折不愈合的成功率更高，为86.7%。既往或活动性感染、钢板或钢钉的存在、患者年龄或受伤时间均不影响治疗结果。对治疗失败病例的分析表明，固定不充分、骨折间隙超过5毫米或骨折间隙中有螺钉是导致治疗失败的原因。4例患者未能确定治疗失败的原因。
