Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults over 18 years old scheduled for long posterior spinal fusion surgery involving 5 or more levels of pedicle screw fixation.

Probably not a fit

Patients with active spine tumors, infections, or those who are pregnant will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the safety and effectiveness of the VersaTie Posterior Fixation System in preventing proximal junctional failure in long posterior spinal fusion surgeries for adults. It compares outcomes between patients using the VersaTie system and those who do not, focusing on complications, clinical results, and patient-reported outcomes. The study also aims to establish best practices for treating complex adult spinal deformities and develop a standardized classification system for complications in spine surgery. Additionally, it assesses blood management strategies and opioid use in relation to patient outcomes.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical outcomes and reduced complications for patients undergoing spinal fusion surgery.

How similar studies have gone: Other studies have shown promising results with similar fixation systems, indicating potential for success in this approach.
