Description

The invention relates to medicine, in particular to traumatology and orthopedics, and can be used to stimulate osteogenesis during bone fusion, improve revascularization of bone regenerate.

There are many ways to stimulate and optimize reparative osteogenesis in the treatment of patients with impaired fusion of tubular bones. The basis of the general and local effects on the course of consolidation are chemical, physical and biological factors. However, despite significant successes in this direction, the treatment of non-united fractures and false joints of long tubular bones presents significant difficulties and often does not bring the desired results.

A known method of stimulating osteogenesis, based on extracorporeal laser-ultraviolet irradiation of autologous blood with slow bone fusion (A.Yu. Kanykin, N.V. Kornilov, V.P. Moskalev and others. Diagnosis and treatment of disorders of regenerative and reparative osteogenesis in case of tissue damage -motor system. - PE "Galenko." - SPb., 2002. - S.32-35).

The disadvantage of this method is only the general effect on the body without local bone irradiation, which, in our opinion, reduces the efficiency of stimulation of regeneration.

The prototype is a method of surgical stimulation of osteogenesis with Beck bone fusion, based on the implementation of drill channels passing through the fracture line in the proximal and distal fragments (G.S. Yumashev. Traumatology and orthopedics. - M., Medicine, 1990. - P. 94 ) Violation of the locking plates at the ends of the fragments contributes to a better formation of regenerate, vascular recanalization, and ultimately bone fusion.

The disadvantages of the method can be attributed to the invasiveness of the intervention and the possibility of infection of the wound, which saves the risk of postoperative complications.

The invention is aimed at increasing the efficiency of treatment of patients with delayed consolidation of fractures, false joints of bones due to local application of high-energy laser exposure to the ends of bone fragments. Laser tunneling of the ends of fragments contributes to the optimized formation of bone regenerate, is a minimally invasive technique, and sharply reduces the possibility of suppuration.

The method is performed according to the following procedure. The patient is in a horizontal position. Under local anesthesia in the fracture area at the points indicated by the results of X-ray studies, a Dufo needle at a 45 ° angle puncture soft tissues in the direction first from the proximal to the distal fragment.

Under the control of an ultrasound study, reaching the distal fragment, a YAG-N surgical laser with a wavelength of 1.06 μm is passed through the needle. After that, fan-shaped at a distance of 0.5-1.0 cm from each other, 10-12 perforation holes are formed by short-term pulse irradiation of the bone with laser light with a power density of 7-10 W and an exposure of 30 seconds per point. The diameter of the holes was 1-1.5 mm, and the depth was 2-3 cm. After this, a similar procedure was performed from distal to proximal fragment. Schematically, the method is shown in the drawing.
