METHOD FOR TOTAL CALCANEAL DEFECT REPLACEMENT IN GUNSHOT WOUNDS Russian patent published in 2025 - IPC A61B17/62 

FIELD: medical science.

SUBSTANCE: invention refers to medicine, namely to traumatology and orthopaedics, and can be used for total calcaneal defect replacement in gunshot wounds. After resection of the remaining dead fragments of the calcaneal bone, excision of non-viable soft tissues and closure of the skin wound defect by secondary healing or application of free and non-free plastic surgery, ankle fusion and fixation with an Ilizarov's apparatus are performed. After achieving ankylosis of the ankle joint, a U-shaped osteotomy of the distal epiphysis of the tibia is performed, during which performing the osteotomy of the lateral and medial edge of the distal epiphysis of the tibia with a width corresponding to the block of the ankle bone, and in the proximal direction by a length necessary to replace the calcaneal defect, then connecting longitudinal saw cuts by performing osteotomy of tibia in transverse direction. Vertical osteotomy of ankle neck is performed, and fragments are fixed with Ilizarov’s apparatus. In 7 days, the calcaneal defect is replaced by graduated displacement of the osteotomised fragment of the distal tibial epiphysis and ankle block at a distraction rate of 1 mm a day. After the extremity segment length is restored, the shin and foot are fixed in the Ilizarov's apparatus until the formed bone regenerate portion is reshaped into the mature bone tissue.

EFFECT: method provides the restoration of the support ability of the lower extremity, as well as the viability of the displaced bone block ensured by the formed single circulation in the tibial and ankle system.
