摘要：
FIELD: medicine.SUBSTANCE: invention relates to medicine, namely to orthopedics, and is intended for use in treatment of varus or valgus gonarthrosis. At varus gonarthrosis, the operation is performed from medial access in the proximal part of the tibia, with valgus gonarthrosis from lateral access. Osteotomy zone passes 2.5–3.0 cm distal to the articular surface of the knee joint, while the opposite cortex of the tibia does not intersect. After performing osteotomy and expanding the edges of the fragments with an impactor, a wedge-shaped device with a variable height with an angle of 8 degrees is implanted into the osteotomy zone, with dimensions of 32 to 18 mm and a height of 7 mm and 9 mm, or 11 mm and 13 mm. Surfaces of the device come into contact with the osteotomized cortical layers of the tibia, intraoperatively change the dimensions of the device from 7 mm and 9 mm to 10 mm and 12 mm, or from 11 mm and 13 mm to 13 mm and 15 mm, fixing in the intermediate value upon correction. Thus, it is possible to correct the axis of the lower limb by changing the base of the wedge from 9 to 15 mm. Correction control is performed intraoperatively by an electron-optical transducer and clinically. Then fragments of the tibia are fixed with a plate with 4 screws.EFFECT: method allows for rapid correction of the required deformation angle, as well as simultaneous correction of flexural deformation in the knee joint.1 cl, 2 exИзобретение относится к медицине, а именно к ортопедии, и предназначено для использования при лечении варусного или вальгусного гонартроза. При варусном гонартрозе операцию выполняют из медиального доступа в проксимальном отделе голени, при вальгусном гонартрозе - из латерального доступа. Зона остеотомии проходит на 2,5-3,0 см дистальнее суставной поверхности коленного сустава, при этом противоположный кортикальный слой большеберцовой кости не пересекают. После выполнения остеотомии и раздвижения краев отломков импактором в зону остеотомии имплантируют
