From 5 to 10% of long bone fractures leads to delayed union. Non-unions can be radiographically classified into hypertrophic or atrophic.

Despite the lack of physical sensations of the magnetic field influence it affects the human organism This impact is defined as a biological effect.

Summary of study results concerning the impact of magnetotherapy in the treatment of ankylosing spondylitis (AS) also known as Bechterew's disease.

Osteoporosis is a disease leading to increased risk of bone fractures. The reason for the bone fractures is the loss of bone volume and mass, as well as pathological changes in the bone microarchitecture. For over thirty years, studies have been conducted on the application of variable magnetic field in treatments of cardiovascular disorders. Encouraging results convinced the U.S. Food and Drug Administration (FDA) agency to accept the therapy with the use of alternating magnetic field as a safe and effective method for the treatment of osteoporosis.

The magnetic field is a kind of invisible and imperceptible impact. The magnetic field occurs naturally in nature, eg in the form of the Earth's magnetic field. The evidence for its existence is a well-known compass, or more precisely the fact of placing a magnetized and longitudinal object in a particular privileged position, mounted in a way that eliminates friction.
