INDIVIDUAL RESECTIONAL BLOCK FOR THE EXECUTION OF OSTEOTOMY OF THE MEDIAL EXOSTUS OF THE HEAD OF THE FIRST PLAINE BONE

摘要

The invention relates to medical technology and can be used to perform osteotomy of the medial exostosis of the head of the first metatarsal bone.;A device for performing foot osteotomy is proposed, characterized in that it has a body made in the form of a rectangular cell with a linear vertical slot, provided with a support platform containing holes made with the possibility of fixing the template to the bone with the spokes, and the lower part of the support platform follows the outline of the outer the surface of the bone on which it is applied, and the location of the linear slot and through holes made in the body, corresponds to the result of 3D modeling, based on data from computed tomography of the foot. In the case can be additionally performed the excavation of a cubic form for the installation of the tool "Osteoguides".;The location of the linear slit and through holes made in the plastic frame is made on the basis of the results of 3D modeling based on data from computed tomography of the foot. The block, as a rule, is performed by printing on a 3D printer.;The use of the claimed device greatly simplifies the technique of performing osteotomy of the medial exostosis of the head of the first metatarsal bone, increasing the accuracy of execution by eliminating the probability of an oscillating saw blade shifting when performing osteotomy, thereby reducing time and reducing trauma. Its use made it possible to eliminate the need to perform X-rays during surgical treatment and to reduce the duration of surgical treatment by 30 minutes.
