Can a Bone Stimulator Aid in Repairing Bones?

AI Thread Summary
The discussion centers on the potential for bone repair stimulation through electromagnetic (EM) fields. Initially, there was a belief that EM fields from electric blankets could harm bones, leading to design changes in these products. However, some claims now suggest that EM fields might actually be beneficial for bone healing. While bone growth stimulators are recognized in medicine for promoting healing through electrical current, the conversation explores the concept of using time-variant magnetic fields to induce currents in materials like copper wire, hypothetically placed within bones. Concerns are raised about the practicality and safety of such methods, particularly regarding the implications for MRI scans. The effectiveness of devices prescribed for post-surgery recovery is also mentioned, with references to anecdotal evidence from medical professionals at UCSF. Overall, the discussion highlights the ongoing debate about the credibility and application of EM fields in bone repair.

Is there such a thing as bone repair stimulation through EM fields?

Years ago, the belief was that electric blankets were harmful for bones because of the EM fields created (and then electric blanket designs were changed to use paired wire configurations to cancel out the EM fields), now these guys are claiming it's beneficial. :rolleyes: I'm not sure if EITHER claim was/is credible.
 
I know that bone growth stimulators are used in medicine, but that relies on the flow of electrical current, not EM.
 
Ahh, but you see, if you had made a loop of say copper wire or something inside the bone, then applied a time-variant magnetic field, you'd get current in the wire!

Oh, yeah, umm... I wouldn't get an MRI after that point, though.

Yes, induced currents do come to mind, but one would expect the currents to be far too small since most people don't have a copper wire inside their bones.
 
Here is some info from the University of Oregon. Ivan's mom had back surgery at UCSF over a year ago and her doctor prescribed one for her to help speed the repair caused by numerous back surgeries. Not the most comfortable of devices, but the neuro guys at UCSF say they help...
