Abstract
The present invention relates to a spinal fixation apparatus having a segment flexible rod for connecting pedicle screws and a transverse link for spacing out the rods, which are made from a shape memory alloy, thereby easily and simply connecting the rods and the pedicle screws. According to the present invention, it can easily and simply fit the rods to the misaligned pedicle screw, even if it may be a failure of alignment of the pedicle screws in surgery. Also, it can easily set up the transverse link on a pair of the longitudinal rods, even if the longitudinal rods are declined or are not in parallel.
