What this trial studies

This observational study aims to assess the effectiveness of the iFuse Bedrock technique in reducing post-operative pain in patients undergoing multilevel posterior lumbosacral fusion. It involves monitoring patients for lumbar and sacroiliac joint pain using various pain assessment tools over a 12-month period. Additionally, a CT scan will be performed at the end of the study to check for any complications related to the iFuse system. The study is multicentric and includes multiple medical centers to gather a diverse patient population.

Who should consider this trial

Good fit: Ideal candidates are patients scheduled for open posterior lumbosacral fusion who have sacroiliac joint dysfunction and meet specific inclusion criteria.

Not a fit: Patients with major osteoporosis or those who have previously undergone sacroiliac joint fusion may not benefit from this study.

Why it matters

Potential benefit: If successful, this technique could significantly reduce post-operative pain for patients undergoing complex spine surgeries.

How similar studies have performed: While this approach is innovative, similar techniques have shown promise in reducing post-operative pain in other surgical contexts.
