Nine delayed unions and nonunion of the proximal fifth metatarsal were treated with pulsed electromagnetic fields (PEMF). All fractures healed in a mean time of 4 months (range 2-8 months). Those fractures treated with both pulsed electromagnetic fields and a nonweightbearing cast healed in a mean time of 3 months (range 2-4 months). The average duration of follow-up was 39 months (range 24-60 months). There were no refractures. When compared with reported healing times and morbidity for conventional casting, medullary curettage with inlay bone, and closed axial intramedullary screw fixation, pulsed electromagnetic fields provided an effective alternative for the treatment of delayed unions and nonunion of the proximal fifth metatarsal.
9例第五跖骨近端延迟愈合和骨不连患者接受了脉冲电磁场（PEMF）治疗。所有骨折平均在4个月（范围2 - 8个月）内愈合。那些接受脉冲电磁场和非负重石膏固定治疗的骨折平均在3个月（范围2 - 4个月）内愈合。平均随访时间为39个月（范围24 - 60个月）。无再次骨折发生。与传统石膏固定、髓腔刮除植骨及闭合轴向髓内螺钉固定所报道的愈合时间和发病率相比，脉冲电磁场为治疗第五跖骨近端延迟愈合和骨不连提供了一种有效的替代方法。
