METHOD FOR SUBSTITUTING DEFECTS OF LONG TUBULAR BONES IN THE CASES OF CHRONIC OSTEOMYELITIS Russian patent published in 2001 - IPC

FIELD: medicine. SUBSTANCE: method involves removing the injured portion of bone during operation. When making resection, 0.6-0.8 cm thick cortical plate connecting the proximal and distal parts of the bone is retained. Bone autograft is cut out from the proximal bone segment continuing the cortical plate. The bone autograft has width equal to the bone defect width and length twice as large as the vertical dimension of the resected bone area. Two crossing wires are brought through the autograft and fixed in the external fixation apparatus. The autograft is transferred when operation wound and fistula passages are healed. The transfer is carried out in continuous way. The transfer is carried out first in pendulum-like mode with distraction rate of 0.5 mm/day during the first 20 days and then, 1 mm/day. After passing a half of the vertical removed bone segment dimension, the autograft is set into translation movement with distraction rate of 1 mm/day until it is brought in engagement with the distal bone segment. EFFECT: accelerated treatment course. 9 dwg
