Plain-language summary
This study is being conducted to evaluate the clinical and radiographic outcomes of three different interbody implant types when used with cancellous allograft chips with BMA or cellular allograft in patients undergoing XLIF surgery. The study will evaluate success by comparing the rate of fusion, complications profile, and any relationships between clinical outcomes (pain and function) and radiographic outcomes (fusion rate) between the three implant groups.

Inclusion criteria
. Male and female patients who are 18-80 years of age;
. Planned interbody fusion surgery, including at least one level of extreme lateral interbody fusion (XLIF) prior to enrollment in the research at one or two consecutive lumbar levels for degenerative disc disease, including those with up to Grade 2 spondylolisthesis, with one of the following NuVasive, Inc. interbody implants:
. Coroent® XL PEEK interbody implant; or
. Modulus® 3D-printed titanium interbody implant; or
. Cohere® XLIF Porous PEEKTM interbody implant.
. Smooth PEEK: Coroent XL PEEK (XLIF) + Coroent L (TLIF) or Coroent XLR (ALIF) or Brigade (ALIF)
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
. Use of BMP, synthetic bone graft substitutes, allografts, or any other graft material in the interbody or intrafacet spaces other than those under study;
. Posterior grafting other than the allowed intrafacet fusion at the treated level(s);
. Revision of prior fusion at treated level(s) (adjacent level interbody fusion is acceptable);
. XLIF procedure that requires or results in the release of the anterior longitudinal ligament or posterior osteotomy;
. Preoperative coronal Cobb angle of ≥ 10°;
. Procedures performed with XLIF interbody implants with integrated vertebral body screw(s);
