When a bone is broken because of an overload of force or a force applied in a non-physiological direction, usually in a sudden manner, a fracture occurs.

The fracture usually heals within a few months through various stages that lead gradually to the formation of repair tissue (callus) and its consolidation, up until the regeneration of the entire bone. The final phase of remodelling, which usually starts six weeks after the fracture, can take weeks or months.

The consolidation of a fracture depends primarily on three variables: the type of fracture, the type of bone concerned and the age of the patient, but in some cases also on certain diseases such as diabetes, renal insufficiency, osteoporosis or bone infections. If the fracture is slow to heal, in other words, if the healing process is not complete within 3 months of the traumatic event or surgery, it is considered a delayed union. In this case the healing process is slower and imprecise. Healing can only be stimulated using adequate measures.

TMR® technology is used today for the treatment of fractures aiming to accelerate the processes of bone repair. It is in fact based on pulsed electromagnetic fields that appear to be able to influence the activity of osteoblasts, cells responsible for the formation of bone matrix. Precisely for this reason, TMR® is of great assistance in curtailing the time of healing and recovery from a delay in bone consolidation.
