May dubel be a solution for pullout problem of the pedicle screws at osteoporotic spine?
AIm: To improve the strength of stabilization systems currently used in osteoporotic spinal fractures, essentially by increasing the fixation force of pedicle screws. mATERIAL and mETHods: Six human cadaveric vertebrae were used. Bone mineral densities of the specimens were measured with Dual Energy X-ray Absorptiometry in order to assess the osteoporosis. All vertebrae were found to be severely osteoporotic. Standard pedicle screws were applied to left pedicles of vertebrae. Pedicle screwsdoi:10.5137/1019-5149.jtn.9718-13.1 pmid:25269044 fatcat:l4xu76nuvvakziueqa6v5j2hja
