METHOD FOR OSTEOPLASTY OF FALSE JOINTS Russian patent published in 2014 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: reposition of fractured bone ends is followed by their longitudinal osteotomy with a twin disk saw of 5 cm in diameter to form two autografts extending one another of the width of 0.8-2 cm and the total length of 7-15 cm, one of which 2.5-5 cm long is sawed out of a smaller fractured bone, and another one 4.5-10 cm long - of a greater one. A single saw of 3.5 cm in diameter is used to extend a longitudinal osteotomy line to both sides by 2-3 cm from each of the two sides of the autografts extending one another, and the same saw is used to connect the ends of the parallel longitudinal osteotomy lines at an angle of about 45 degrees to the long axis of the autografts to form congruent pointed peripheral ends of the autografts. With a flat chisel of the width equal to or a little less than the width of the autografts both autografts are removed and interchanged with the greater one overlapping the false joint. A bone comb prepared by processing the fractured bones is tightly inserted between one of the two lateral sides of the autograft and the bone bed, and between both autografts.

EFFECT: by false joint plasty, the method enables higher clinical effectiveness in patients with non-united fractures and false joints of long extremities and reducing a length of treatment.
