The invention relates to medicine, in particular to the treatment of scoliosis, spondolysis in the lumbar spine.

The purpose of the invention is to improve the local correction of scoliosis of the thoracic and lumbosacral regions while reducing the traumatic ™.

FIG. 1 shows the design of the proposed device; in fig. 2 and 3 - illustrates the operation of the device.

The device contains two half-sleeves 1, repeating the shape of the pectoral rib surface of the body with flared along the edges and interchangeable soft lining and provided with two front and two rear corrective straps 2, tightening the half-sleeves 1 between themselves and forming the breast fixing frame, two half-sleeves 3, covering the supra-pelvic surface of the body with the capture of the crests of the iliac bones, equipped with two front and two rear corrective belts 4, tightening the half-sleeves 3 between themselves and forming the laconic sacral framework a. Half-sleeves 1 and 3 are provided with supporting elements 5, in which rods 6, 7 with right and left screw threads along .kra m, screwed into sleeves, are fixed by means of movable joints.

The orthopedic apparatus is used as follows.

Half-sleeves 1 and 3 are placed on the side surfaces of the body and are pulled together with corrective belts 2 and 4. Due to the movable connection in the supporting elements 5 rods b, 7 half-sleeves have the ability to freely rotate, which contributes to the tight installation of half-sleeves on the patient's body in accordance with the shape chest and supratavial surface and their rigid fixation with the capture of the crests of the iliac bones. Depending on the type of scoliosis, the spine is slowly extended first for 5-10 minutes by simultaneously extending the rods by the same amount by rotating the rods in the screw connection, and then, depending on the pathology, the rods are extended by different values for 15-30 minutes.

In the case of scoliosis shown in the drawing, the rod 7 is lengthened by a large amount until the curvature is straightened and the curvature changes (within 2-5 j.

The half-sleeves 1 and 3, tightly fitting the body, and the rods 6, 7, in combination with the corrective belts 2.4, form a rigid structure that allows considerable effort to be made to stretch the spine with a corrective influence. Due to the tight girth of the half-tips 2 of a significant part of the costal surface, the corrective influence is distributed and does not cause local pressure on the individual ribs. The load is distributed evenly over all edges. The force is transmitted through the rib heads to the vertebrae. The anatomical axis of the spine is repaired. Poluigil0 for 3 tightly wraps the supra-pelvic surface, capturing the iliac bones.

Thus, the force is applied to the iliac crest and the chest, causing the lower thoracic region to become stretched.

5 and on the lumbar spine. The design allows considerable effort to stretch the spine. For 30-50 min., Until the clamped and displaced

0 vertebrae, thereby eliminating disc-radicular conflicts. Skeletal muscle relaxes — pain is relieved and stretching of the links that restore the displaced vertebrae to normal position is relieved.

5 Execution of each of the two half-shell frames allows free access to the spine, which allows for additional manual manipulation of the spine.

The device is installed under the supervision of a physician in the position of the patient standing or lying down.

The course of treatment is from 5 to 30 days. The wearing time of the apparatus is 2-4 hours, depending on the patient’s condition, with intervals between

5 wearing at least 1 hour. The procedure is repeated from 5 to 40 times. In the intervals between wearing the apparatus, a course of strengthening exercises is necessary.

FIG. 2, 3 shows an explanation of the distribution of forces in the case of scoliosis. Belts 2

0 are located symmetrically with respect to the apex of the scoliosis arc so that the half-shells 1 touch protruding parts of the rib surfaces in the region of the apex of the scoliosis arc and at the base of the arc on the other side of this region. The arrows 8, 9 show the forces acting on the ribs, and the arrows 10, 11 show the same forces transmitted through the rib heads to the vertebrae. As can be seen from the figures, the indicated forces correct

0 scoliotic arc.

In the lumbosacral region, the scoliotic displacement leads to a distortion of the pelvic bones and hip joints. With the location shown in the figure

5 belts 4 and given that the distractor 7 is moved apart by a larger amount than diets

Pa who p 6, the forces with which the half-tubes 3 act on the pelvic bones and hip joints are not the same from different sides. The force at points 12 exceeds the force at points 13, which leads to straightening the skew of the pelvic bones and straightening the spine.

Thus, by selecting the relative position of the belts 2 and 4 and the magnitude of the extension of the distractors b and 7, the direction and magnitude of the forces with which the half-sleeves 1 and 3 act on the skeletal-muscular system can be changed.

The proposed device makes it possible to correct not only the major arc of scoliosis, but also local displacements of the vertebrae in the region of the middle and lower thoracic part of the spine and along the lumbosacral region,
