Thirty ununited tibial fractures with a median time since injury of 18+/-9 months were treated by electrical stimulation using pulsing electromagnetic field therapy. Union was achieved in 25 cases (83.3%) in a median interval of 8.6+/-3.2 months. Patient age and gender, the presence of surgical hardware, length of disability, and the number of surgical procedures did not affect the outcome. Ununited fractures that appeared to be hypertrophic or sclerotic type radiographically, indicating a good blood supply to the bone ends, all healed. Treatment failures occurred only among lesions with a poor blood supply, and in necrotic or defective radiopraphic types. Pulsing electromagnetic field therapy is an effective treatment for ununited tibial fractures with good blood supply to the bone ends.
30例胫骨骨折不愈合患者，自受伤至治疗的中位时间为18±9个月，采用脉冲电磁场疗法进行电刺激治疗。25例（83.3%）患者实现骨折愈合，中位愈合时间为8.6±3.2个月。患者的年龄、性别、是否存在外科植入物、残疾时间长短以及手术次数均不影响治疗结果。影像学显示为肥大性或硬化性类型的骨折不愈合，提示骨端血供良好，均实现了愈合。治疗失败仅发生在血供差的病变以及坏死或影像学表现不佳的类型中。脉冲电磁场疗法是治疗骨端血供良好的胫骨骨折不愈合的有效方法。
