ELECTROMAGNETIC RESPONSE IN BONE
Miles F. Buchman · 1971
Bones naturally generate electrical signals during healing, making them inherently sensitive to electromagnetic field interference.
Plain English Summary
This 1971 study by Buchman examined how electromagnetic fields interact with bone tissue, focusing on the natural electrical properties that help bones heal fractures. The research explored bone's piezoelectric characteristics, which generate electrical signals when mechanically stressed, and how external electromagnetic fields might influence these natural healing processes.
Why This Matters
This foundational research from 1971 represents some of the earliest scientific investigation into how electromagnetic fields interact with living bone tissue. What makes this particularly significant is that it predates our modern wireless world by decades, yet already scientists were recognizing that bones have inherent electrical properties that respond to electromagnetic stimulation. The piezoelectric nature of bone means it naturally generates electrical fields when compressed or stretched during normal movement and healing.
This work laid crucial groundwork for understanding how external electromagnetic fields might interfere with or enhance these natural bioelectric processes. Today, as we're surrounded by wireless devices operating at frequencies far beyond what Buchman studied, this early research reminds us that our bodies have always been electromagnetic systems. The question isn't whether EMFs affect us, but how the artificial electromagnetic environment we've created interacts with these natural biological processes that have evolved over millions of years.
Finding
The total electrical potential in bone can be broken down into two parts, the static potential and the dynamic potential. The dynamic potential is the constantly varying time dependent phenomenon discussed above as being induced by stress. It is thought to be responsible for bone maintenance and remodeling as evidenced in the effects described in Wolff's Law.

Study Details
To investigate the electromagnetic response in bone and the potential mechanisms underlying bone remodeling and fracture healing through electrical stimulation.
Experiments were conducted using rabbit tibias and human non-union fractures. Bone samples were test...
In rabbit studies, groups 3 and 5 showed higher degrees of fracture healing when the cathode was pla...
Electrical stimulation can induce fracture healing in both animal and human subjects. The process may involve a transducer mechanism that converts mechanical stress into electrical signals, potentially leading to new therapeutic approaches for bone diseases and fractures. The technique could reduce healing time and avoid the need for expensive surgical bone grafts.
