About this study
Official title: Lumbar Fusion With Micro and Nano-textured Titanium Interbody Cages - A Single-Blinded Randomized Controlled Trial Evaluating Adaptix™ Versus PEEK Cages
The purpose of this randomized controlled trial is to assess and compare radiographic and clinical outcomes in patients who are to undergo combined interbody/posterolateral lumbar fusion procedures, supplemented with pedicle screw instrumentation, using one of the following interbody cages; the Medtronic Adaptix™ cage with roughened micro and nano-textured titanium surfaces or the CAPSTONE® poly-ether-ether-ketone cage.
Read the detailed description
The randomized controlled trial will prospectively evaluate the efficacy of Medtronic Adaptix™ titanium implants supplemented with a pedicle screw system as compared to a Medtronic CAPSTONE® PEEK cage currently used in routine fashion for lumbar interbody fusion procedures. This study will capture clinical and radiographic outcomes on patients up to 2 years postoperatively. Both cages will be used in conjunction with a 50:50 mixture of autograft: allograft using milled local autograft bone and GRAFTON™ DBM DBF (no iliac crest autograft will be utilized).
This single-centered study will enroll up to 100 subjects, with subjects followed for 24 months post-surgery. All subjects enrolled in the study will be recruited from a pool of subjects eligible for combined interbody/posterolateral lumbar fusion surgery. The inclusion/exclusion criteria are listed below.
- Conditions
- Spinal Canal Stenosis, Spondylolisthesis, Osteophyte, Bony Growth Formation, Degenerative Disc Disease
- Being tested
- Medtronic Adaptix™ titanium implants, Medtronic CAPSTONE® PEEK cage

What participants receive. In a randomised study each person is assigned to one group by chance.
Medtronic Adaptix™ titanium implantsDevice
Patients who will be having a spinal fusion procedure as part of their standard of care treatment will be randomized to receive either the Medtronic titanium or the PEEK cage supplemented with a pedicle screw system and milled local autograft bone supplemented with GRAFTON DBM DBF. In order to assess fusion, patients will undergo a research-only CT Scan at 6 months post-surgery.

What is being measured
The primary outcome is the main question the study is designed to answer.
Fusion rate at 6 months
A subject will be considered a success if fusion is a Grade BSF-3 at 6 months. The primary outcome measure of effectiveness will be determined by the fusion rate at 6 months post-operatively in subjects implanted with either titanium cage as compared to the PEEK cage.
Measured: 6 months
Secondary outcomes (1)
Timing of fusion
Secondary measures of effectiveness will be determined by the principal investigator by evidence and timing of fusion observed in X-rays post-operatively (3, 6, 12, and 24 months).
Measured: 24 months

Questions about this trial
What is this clinical trial studying?
A study testing Medtronic Adaptix™ titanium implants and Medtronic CAPSTONE® PEEK cage in people with Spinal Canal Stenosis and Spondylolisthesis, run by Ohio State University at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 25 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Fusion rate at 6 months (time frame: 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05182489, which also lists 17 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Feb 2026.
