A novel technique for stabilization of high-grade spondylolisthesis with transvertebral fusion without reduction.

•One-stage technique manages local malalignment with a technique that minimizes risk.•Bilateral threaded pedicle screws of large diameter and length instead of a single fibula allograft.•Placing pedicle screws with a transvertebral trajectory through the two end plates.•Report on 3 patients- no CSF leaks, intragenic insults, implant failures, or revisions.•The minimal complications and favorable outcomes make this technique an effective, efficient and safe procedure.
