Magnetic rod is a fixing osteosynthesis device used to cure fractures featuring oriented magnetic properties. The device is distinguished for hollow fixation screw filled with freely moving SmCo or NdFeB permanent magnets. Their magnetic moments are oppositely oriented providing separate location of the magnets inside the rod. The magnetic field lines provide an impact on the Ca ions in the direction perpendicular to the fracture line intensifying thereby the regenerative processes. Rods made of a nonmagnetic material eliminate the possibility of screening the magnetic field. Free movement of magnets inside the rod caused by natural movements of the patient provides the effect of "moving magnetic field", which is used in a number of magnetotherapy devices.
