Early Application of Pulsed Electromagnetic Field in the Treatment of Postoperative Delayed Union

Phase 4 Study of Early Applied Pulsed Electromagnetic Field in the Treatment of Postoperative Delayed Union of Long-bone Fractures

The investigators hypothesized that early applied pulsed electromagnetic field treatment on delayed union might lead to increased rate of fracture union and shortened period of treatment.

Inclusion Criteria:

• The failure of healing after at least 16 weeks and not more than 9 months following surgical reduction and fixation of the fracture.

Exclusion Criteria:

• Implant loosening or failure, infection, established nonunion, fracture gap greater than 5 mm, presence of implant within the fracture gap, metabolic disorders or received medication affecting fracture healing
