Durability of Supplementary Rod Constructs-SuppleMentAry Rod Technique (SMART)-for Long-segment Posterior Instrumented Spinal Fusion Procedures: A Multicenter Retrospective Comparative Study With Dual-rod Constructs
AO Foundation, AO Spine
Summary
This is a multicenter retrospective comparative cohort study. The index surgery for this study is primary or revision long-segment posterior thoracolumbar (TL) instrumented fusion using either a supplementary rod construct or a dual-rod construct. Eligible patients who already had index surgery, will be identified for enrollment through a review of medical records of the participating surgeons at the study sites.
Description
This multicenter retrospective comparative cohort study will enroll 1244 patients, who underwent primary or revision long-segment posterior thoracolumbar (TL) instrumented fusion using either a supplementary rod construct or a dual-rod construct. By comparing two groups of patients, ie, patients treated with supplementary rod constructs vs dual-rod constructs, in the setting of long-segment posterior instrumented spinal fusion, this study aims to provide quality evidence regarding the benefits of supplementary rod constructs in reducing the risk of RFs and other mechanical complications.

Inclusion Criteria: * Age 45 years and older. * Patients receiving long-segment posterior TL instrumented fusion using either supplementary rod constructs or dual-rod constructs (the index surgery). * Long-segment is defined as the UIV at a thoracic level and the LIV at the sacrum/ilium. * Supplementary rod constructs are defined as: in addition to the traditional two primary rods, at least one supplementary rod (eg, accessory rods or satellite rods) is used, and at least one supplementary rod and one primary rod (ie, at least two rods) together must span multiple (≥ 2) vertebral levels.…
