About this study

Official title: A Prospective, Nonrandomized Study to Assess Lumbar Fusion Using Interbody Cages With Autograft in Conjunction With Instrumented Posterolateral Gutter Fusions Using nanOss Bioactive and Autograft Bone.

nanOss Bioactive is approved for use in the U.S. The purpose of this study is to compare fusion results in the posterolateral spine using nanOss Bioactive mixed with autograft bone and bone marrow aspirate (BMA) on one side and autograft alone on the opposite side of the treated level(s). It is hypothesized that the use of nanOss Bioactive will result in fusion at 12 months, with CT evidence of bridging trabecular bone, less than 3mm of translational motion, and less than 5 degrees of angular motion.

Read the detailed description

The post market clinical investigation is designed to assess instrumented posterolateral fusion (PLF) using nanOss Bioactive bone void filler with autograft bone and bone marrow aspirate in patients with symptomatic spinal stenosis secondary to degenerative disc disease with up to Grade 1 spondylolisthesis at one or two adjacent levels from L2-S1.

Preoperatively, the participant will provide his/her medical history and complete self assessment forms. The investigator will perform a clinical evaluation and x-rays will be performed if recent x-rays are not available. Participants will undergo instrumented PLF with an interbody fusion device (with autograft or allograft) using nanOss Bioactive in combination with autograft bone and bone marrow aspirate in one posterolateral gutter and autograft alone in the opposite posterolateral gutter.

Following surgery, operative and discharge information will be collected and a clinical evaluation will be performed prior to discharge. Participants will be evaluated 6 and 12 months postoperatively. One investigational site will participate in long-term followup of 24 months. Each participant will complete x-rays and self assessment documents. A CT scan performed at the 12 month postoperative visit will be evaluated by an independent radiologist to assess fusion results. Complication data will be recorded throughout the study.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • nanOss Bioactive - posterolateral gutterDevice

    Participants will undergo instrumented PLF at one or two adjacent levels from L2-S1 with PEEK interbody cages (containing allograft or autograft) using nanOss Bioactive in combination with autograft and bone marrow aspirate in the posterolateral gutter on one side. Autograft alone will be used in the opposite posterolateral gutter.

Questions about this trial

What is this clinical trial studying?

A study testing nanOss Bioactive - posterolateral gutter in people with Degenerative Disc Disease and Spinal Stenosis, run by Pioneer Surgical Technology, Inc. at 3 sites 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 9 inclusion and 20 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: finished, as of the sponsor's last update on 8 Nov 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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 (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 8 Nov 2016.
