The Presacral Approach (AxiaLIF)
The presacral approach (AxiaLIF) offers a minimally invasive fusion option for the L5-S1 (or the L4-L5 and L5-S1) discs, taking advantage of the presacral space and transsacral trajectory. Supplemental posterior stabilization with either percutaneous facet or pedicle screws is indicated, in order to limit rotation. This technique is particularly useful in patients with low-grade spondylolisthesis, after reduction with the percutaneous pedicle screws, and in patients with collapsed discs following a previous laminectomy and discectomy.
