  • Title: The Canadian experience with pulsed magnetic fields in the treatment of ununited tibial fractures.
    Author: de Haas WG, Beaupré A, Cameron H, English E.
    Journal: Clin Orthop Relat Res; 1986 Jul; (208):55-8. PubMed ID: 3720140.
    Abstract:
    A clinical survey of 56 patients was conducted at four different centers in Canada to evaluate the effect of extremely low frequency pulsed magnetic fields (PMF) on ununited fractures of the tibia. All ten patients with delayed union and 84% of the 44 patients with nonunion healed. One case with a traumatic pseudarthrosis and one with a congenital pseudarthrosis failed to respond to treatment. These results compare favorably to those reported by others using a system with different pulse characteristics. Prolonged immobilization is necessary and poses problems of rehabilitation. Nonunions with a gap between the tibial fragments and pseudarthroses are better treated with bone grafting and internal fixation prior to electrical stimulation.
