The invention relates to the treatment of different bone injuries, particularly fractures and fissure fractures, and can be used in medical and veterinary therapy and surgery. In order to reduce the time taken for bone tissue to regenerate at the site of damage or a defect and to reduce the time taken for the normal physiological functioning of an injured bone to be restored, 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)°С, is held at this temperature for (1-48) hours and is then cooled to room temperature. As a result, there is a significant (20-25%) reduction in the time taken for bone tissue to regenerate at the injury site, irrespective of the type of animal which has sustained the injury. The above-mentioned solution for injection has low toxicity and good storage properties and can be kept for an extended period of time without loss of activity.L'invention concerne le domaine du traitement de différentes lésions de l'os, notamment des fractures et des fissures, et peut s'utiliser en thérapie ou en chirurgie médicale ou vétérinaire. Afin de réduire le temps nécessaire pour la régénération du tissu osseux sur le site de la lésion ou de l'anomalie et pour réduire le temps nécessaire au rétablissement de la fonction physiologique normale d'un os endommagé, une méthode est utilisée pour la régénération du tissu osseux par la fixation de fragments de l'os endommagé avec un bandage en plât
