Hi,
I have successfully used pulsed magnetic field generators to improve delayed bone union post fracture or surgery. The cases I used the unit on were quite chronic non or delayed unions, and had not responded to various other medical options such as bone grafting, plastering, antibiotics etc
The theory is that the normal low level electrical charge that occurs when bone is under stress cannot occur if the fractured bone ends are too distracted, or there is a plug of insulating tissue such as infection etc. The normal callus formation does not occur without the electrical stimulation across bone ends, therefore no calcification of callus.
A pulsed magnetic field is required to ensure the artificial electrical stimulation generated by the collapsing field effect. Static magnets do not provide this stimulation.
I have not published my results, nor can I validate the findings, other than to state that healing had not occurred in these cases with any other intervention over 6 - 12 months, until the pulsed magnetic field was trialled. Improvement was noted on x-ray review within 6 weeks, with further improvement following later.
Once healing began, the usual treatments were recommenced.
Hope the above is of interest.
