Abstract: The invention relates to the treatment of different bone injuries, particularly fractures and fissure fractures. In order to reduce the time taken for bone tissue to regenerate at the site of damage, a method is used for regenerating bone tissue by fixing fragments of the damaged bone with a plaster cast or a bandage made of a polymer material and introducing into the fracture zone an aqueous solution containing 1-hydroxyethylidene diphosphonic acid in an amount of (1.80-2.06) g/l, anhydrous calcium chloride in an amount of (1.44-2.22) g/l, gadolinium (III) nitrate hexahydrate in an amount of (0.30-0.40) g/l and dysprosium (III) chloride hexahydrate in an amount of (0.038-0.076) g/l, with a pH of (7.3-7.8), wherein, prior to being introduced into the fracture zone, the above solution is brought to a temperature of (30-100°) C., is held at this temperature for (1-48) hours and is then cooled to room temperature.
