Impact of dual-headed pedicle screws on the biomechanics of lumbosacral junction multirod constructs.

CONCLUSIONS: RS across the lumbosacral junction can be high. Supplemental rod fixation with DTH is an effective strategy for reducing RS across the lumbosacral junction. However, the greatest reduction in RS and SM was achieved with a VAC that allowed for straight (uncontoured) accessory rod placement.
