➢ The use of multirod constructs (≥3 rods) in complex spine surgery has increased as its utility has been recognized over the past decade.➢ There are multiple different rod configurations that may be utilized on the basis of the desired supplemental rod function, with each type having its own advantages and clinical indications.➢ Literature has continued to demonstrate a reduced incidence of pseudarthrosis, rod fracture, and reoperation when comparing multirod constructs with traditional dual-rod constructs.➢ The use of consistent nomenclature when describing multirod constructs will allow for more productive clinical and biomechanical research.

Objective: Multipoint pelvic fixation with multirod constructs is increasingly used for long-segment deformity constructs to reduce rates of distal failure. However, more robust distal fixation may negatively impact proximal junction biomechanics, and this potential relationship has not been extensively studied.
Methods: Standard nondestructive flexibility tests (7.

Purpose: To introduce and report early outcomes of an innovative surgical strategy to stabilize L5 PSOs with minimum 6 rods utilizing bilateral dual pelvic fixation consisting of both traditional iliac screws and osseointegrative S2AI screws.
Methods: Adult patients at a single institution who underwent a L5 PSO reconstructed with a minimum of 6 rods using dual pelvic fixation were reviewed. Accompanying a description of the surgical technique is patient demographics, perioperative sagittal radiographic alignment parameters, and early surgical and clinical outcomes, including incidences of mechanical complications.

Background And Objectives: Three-column osteotomy (3CO) is a powerful corrective technique in adult spinal deformity. Unfortunately, they carry high complication rates including mechanical complications (MC) of rod fracture and pseudoarthrosis. Owing to the rapidly aging population, this intervention will only increase in use.

Study Design: Single-center retrospective cohort study.
Objective: To determine if the 4-rod construct (4RC) is protective against the occurrence of rod fractures when compared with the 3-rod construct (3RC) in adult spinal deformity (ASD) patients with long fusions to the sacrum.
Summary Of Background Data: Past studies have explored the different outcomes in subjects with dual-rod versus multirod constructs.
