In most cases of nonunions, healing occurs with rigid fixation of the fragments alone and without any electric stimulation. Most non-unions are programmed by nature to unite. In the majority of cases, the bone ends are well vascularized, much more so than in fresh fractures. Therefore, grafting after rigid fixation is generally unnecessary. Autologous cancellous bone transplant, however, is essential in avascular and infected nonunions. Rigid fixation not only has a very high rate of union, but also the advantage that malalignment and shortening can be corrected and that functional after treatment is possible. Nonsurgical treatments, including electrical stimulation, may also produce union but cannot correct concomitant deformity or other disabling lesions of the limb.
在大多数骨不连病例中，仅通过对骨折碎片进行坚强固定即可实现愈合，无需任何电刺激。大多数骨不连从本质上来说都有愈合的趋势。在大多数情况下，骨端血运良好，比新鲜骨折时的血运状况要好得多。因此，坚强固定后通常无需植骨。然而，自体松质骨移植对于缺血性和感染性骨不连至关重要。坚强固定不仅愈合率很高，而且还具有能够纠正畸形和缩短、治疗后肢体功能良好的优点。包括电刺激在内的非手术治疗也可能实现愈合，但无法纠正肢体的伴发畸形或其他致残性病变。
