Answer

Pedicle screws have also become a popular anchor for the rods used in posterior scoliosis fusion procedures. [131] They offer the potential advantage of increased strength (and possibly power of correction) while at the same time introducing added insertion-technique complexity and different neurologic complication risks. A very real and major increase in the overall cost of instrumentation constructs that include many pedicle screws is the case when they are compared to similar constructs that may include hooks and wires.

At this time, the available evidence in favor of a commensurate improvement in clinical outcomes is not sufficiently conclusive to support routine use of such pedicle screw constructs in the treatment of idiopathic scoliosis.
