Stabilization of L5 pedicle Subtraction osteotomies (PSO) with ≥ 6-rods and bilateral dual pelvic fixation with osseointegrative implants: surgical technique description and early postoperative outcomes

Bilateral dual pelvic fixation consisting of traditional iliac screws and osseointegrative S2AI screws to facilitate creation of "super" multi-rod constructs (minimum 6 rods) across L5 PSOs is a safe surgical strategy with promising early clinical results. Larger cohorts from multiple centers with longer follow-up will aid in determining its long-term efficacy.
