METHOD FOR FEMORAL LENGTHENING Russian patent published in 2015 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: when applying an external fixation apparatus, two threaded rods are inserted into a proximal metaphysis of the femoral bone, perpendicularly to a long bone axis; one rod is inserted at the level I in the position 9, and the second one - at the level II in the position 11 and fixed in a proximal extreme outer locating support. A pin supported from an inner thigh at the level VIII from the position 3 to the position 9 and a threaded rod at the boundary of the levels VII and VIII in the passage position 8-9 at an angle of about 45° to the long femoral axis are inserted into the distal femoral metaphysis intra-articularly and fixed in a distal extreme outer locating support. A femoral diaphysis osteotomy is performed through a mini-incision from an outer thigh. The femoral fragments are displaced in relation to each other. After performing a distraction, the threaded rods are inserted one into each femoral fragment perpendicularly their long axis from the outer thigh; that ensures eliminating the femoral fragment dislocation with recovering the anatomical axis of the femoral bone, and they are fixed in their middle outer supports of an external fixation apparatus.

EFFECT: method enables forming the adequate graft.
