Summary

This trial compares two types of cages used in back surgery for patients needing spinal fusion. One cage is made of porous titanium, and the other is titanium-coated PEEK. The cages help bones in the spine grow together and stabilize.

Who is the study for?
This trial is for adults over 18 who need lumbar fusion surgery and haven't responded to non-surgical treatments for at least 6 months. They must be able to follow the study plan and give consent. Exclusions include previous lumbar fusion, substance abuse, pregnancy, ongoing litigation or compensation claims related to back pain, infections, metal sensitivity, extreme obesity (BMI >40), certain medical conditions or medications affecting bone healing.
What is being tested?
The trial compares two types of spinal cages used in lumbar fusion surgeries: one made from porous titanium and another coated with titanium on PEEK material. Participants will be randomly assigned to receive either cage during their scheduled surgery.
What are the potential side effects?
Potential side effects may include typical surgical risks such as infection, pain at the site of surgery, bleeding, nerve damage or reactions specific to the materials used in the cages like inflammation or allergic responses.

Trial Design

2Treatment groups
Active Control
Group I: CONDUIT Porous Titanium Spinal CageActive Control1 Intervention
Solid titanium spinal cage, infused with microscopic, porous canals to allow for adhesion and proliferation of bone graft factors contributing to spinal ossification, and ultimately, spinal fusion between vertebrae demonstrating instability.
Group II: PROTI 360 Titanium-Coated PEEK Spinal CageActive Control1 Intervention
Spinal cage composed primarily of a medical-grade polymer: poly-ether-ether-ketone (PEEK), with a titanium coating that is etched, but lacking porous features. These design features also attempt to stimulate spinal vertebrae fusion through bone-graft ossification and enhance vertebral stability.

Other Research
Porous Titanium Cages provide a scaffold for bone growth and integration, promoting osseointegration by allowing bone tissue to grow into the porous structure, which enhances the stability and long-term success of the fusion. Non-Porous Titanium-Coated PEEK Cages offer a biocompatible surface that reduces the risk of adverse reactions while maintaining the structural benefits of PEEK, such as its radiolucency and mechanical properties similar to bone. These mechanisms are crucial for lumbar fusion patients as they ensure better bone integration, stability, and compatibility, leading to improved clinical outcomes and reduced complications.
