Prospective, Multicenter, Case-Control Analysis of the VersaTie Posterior Fixation System to Prevent Proximal Junctional Failure in Long Posterior Spinal Fusion Constructs for Adult Patients
Specific Aims: * Evaluate the safety and performance of posterior spinal fusion constructs supplemented with posterior spinolaminar fixation using the VersaTie System compared to posterior fixation constructs without VersaTie System supplementation in adult patients undergoing long posterior spinal fusion by evaluating intraoperative and postoperative complications, clinical and radiographic outcomes, patient-reported outcomes (PROs) and need for revision surgery. * Evaluate surgical treatment outcomes and identify best practice guidelines for complex adult spinal deformity (ASD) patients, in…
