METHOD OF INTRAMEDULLARY FIXATION OF BONE AND GUIDE TOOL FOR PRECISION ALIGNMENT OF AXES OF SYMMETRY OF INSTRUMENT GUIDES WITH AXES OF SYMMETRY OF INTRAMEDULLARY ROD HOLES Russian patent published in 2019 - IPC A61B17/58 

FIELD: medicine.

SUBSTANCE: group of inventions relates to traumatology and orthopaedics, and can be used for intramedullary fixation of bone with bone-marrow canal. Guide tool for precision alignment of axes of symmetry of holes of instrument guides with axes of symmetry of intramedullary nail holes in intramedullary fixation of bone with bone-marrow canal includes shoulder for implantation of rod into a longitudinal bone canal, releasably connected to the proximal end of the shaft such that it is continuously directed relative to the distal portion of the intramedullary nail; mounted on arm of guiding tool guides having cylindrical shape and installed in many planes; guide device also includes a threaded end having a support surface and a mounting probe connecting the position of the cylindrical guides relative to the holes in the distal portion of the rod; a bushing installed with the possibility of blocking onto the setting connection probe. Mounting connecting probe, placed in hole of one of cylindrical guides guide tool, is screwed into appropriate hole of rod to support surface of probe. Sleeve installed at appropriate height relative to guide tool is blocked. Probe is removed from guide tool. After the rod is inserted into the medullary canal, a hole is made in the bone, which coincides with the corresponding opening in the distal portion of the intramedullary nail. Probe is placed in appropriate holes of guides and through hole made in bone is screwed to support surface into corresponding hole of rod, locking guiding tool at certain height, and performing the remaining holes in the bone for locking screws passing through the corresponding holes in the rod.

EFFECT: group of inventions enables avoiding the consequences associated with radiological monitoring, ensuring correct installation.
