FIELD: medicine. ^ SUBSTANCE: body of C2-C3 disk is approached. Through a base of C2 vertebra, pins are introduced into a fragment of dens. Screws with a through axial channel are inserted on the pins to be removed thereafter. After approach to the C2-C3 body, an apparatus under cl.2 with its pointed flange of a base body is introduced into the C2 vertebral body from the C2-C3 disk. The opposite end of the base body together with an attached pair of oblong bodies is displaced downwards with raising and displacing anteriad the C2 vertebral body. At displacing downwards and keeping the pointed flange and the C2 vertebra in contact, the lower part of the pointed flange is shifted inside of the C3 vertebra until the axes of longitudinal through apertures of the oblong bodies are in the plane with the axis of dens and the fragment. The required direction is fixed to introduce a pair of pins through the apparatus under cl.2 into dens further. The apparatus for introducing the pins to tread the screws with the through axial aperture therethrough, herewith fixing C2 vertebral dens fracture comprises a base body supplied with at least a pair of the oblong bodies attachable to the base body. The oblong body is provided with the longitudinal through aperture formed for said pint, and a pointed end. Axes of the longitudinal through apertures from the pointed ends are at an acute angle to each other. The base body has a pointed flange concerning a plane passing through the axes of the longitudinal through apertures of the oblong bodies, and symmetrised between the pair of the oblong bodies. ^ EFFECT: inventions provide precise one-stage introduction of two spokes in dens, reduced surgery time and complexity. ^ 5 cl, 1 ex, 19 dwg |
