Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 35 to 80 with degenerative disc disease and foraminal stenosis who require lumbar fusion surgery.

Probably not a fit

Patients over 80 years old, current smokers, or those with significant spinal deformities will not benefit from this study.

What this trial studies

This observational study aims to assess the clinical outcomes and spine fusion rates in patients undergoing transforaminal lumbar interbody fusion (TLIF) using a 3D printed titanium implant. It will recruit patients with lumbar spinal conditions who have not responded to conservative treatments. Participants will be monitored at six-month intervals for two years to evaluate patient-reported outcomes, clinical results, and radiographic parameters, particularly focusing on fusion rates. The study is a post-market evaluation of the CONDUIT 3D printed titanium TLIF cage.

Why it matters

Potential benefit: If successful, this study could improve surgical outcomes and recovery for patients with lumbar spinal conditions.

How similar studies have gone: Other studies have shown promising results with similar 3D printed implants, indicating potential for success in this approach.
