METHOD FOR CORRECTION OF MULTI-LEVEL DEFORMATIONS OF LONG-BONES Russian patent published in 2018 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: transosseous elements are directed and the proximal, distal and intermediate supports of the external fixation apparatus are mounted. Osteotomy is performed at the level of each of the deformation vertices. An orthopedic hexapod is mounted. Hexapod strata are fixed only to the proximal and distal supports, and the intermediate supports are connected with ones located above and below by means of elastic rods. Hexapod parameters and pre-operative planning data are input into a computer program and the computer program is used to calculate the deformation correction by combining the distal fragment axis with the proximal fragment axis. Then the lengths of the hexapod strata are changed manually based on the calculations performed, thus making simultaneous correction of deformations at all levels. The elastic rods and hexapod strata are replaced with fixed articulations or straight threaded rods.

EFFECT: method allows to increase stability of fixation, provide conditions for regenerates rebuilding.
