摘要：
FIELD: medicine.SUBSTANCE: invention refers to medicine, namely to orthopedics, and can be used in treating deformation of locomotor system and structures providing strong fixation of bones. Dorsal approach is performed longitudinally above 4th metatarsophalangeal joint in the proximal direction to the level of the prospective osteotomy. Metatarsophalangeal joint is opened, metaepiphysis and diaphysis of metatarsal bone are recovered in place of osteotomy. Performing the transverse osteotomy, the saw blade is exposed parallel to the frontal plane of 4th metatarsal bone at distance of 1.5 cm from the articular cartilage line of the metatarsophalangeal joint from the rear to the sole of the foot, wherein the saw blade is placed at angle of 90 degrees to the horizontal plane of the metatarsal bone. Stage of transplant sampling from 5th metatarsal bone is performed. External surface along 5th metatarsophalangeal joint is projected in a projection of a prospective osteotomy, a metatarsophalangeal joint is opened. First osteotomy is performed at 1 cm from the boundary of the articular cartilage proximally； the saw blade is oriented perpendicular to the metatarsal bone from the outside to the inside； a line parallel to the metatarsal bone is applied, and it is retreated proximally to the distance required for the transplant. Second osteotomy parallel to the first one is performed so that a transplant of cylindrical shape is obtained, the obtained graft is placed into physiologic saline. Head of 5th metatarsal bone is aligned with diaphysis of 5th metatarsal bone, temporary fixation of osteotomy of 5 metatarsal bone by K-wire is performed, wire is passed through proximal fragment, point of needle input is located on external side of metatarsal bone, wire is oriented into medullary canal to distal end of head of metatarsal bone, cortical layer is reamed by cannulated drill to chondral layer of head of metatarsal bone. Fragments are recorded by conducting a cannulated self-dr
