About this study

Official title: Osteocel® Plus in Anterior Cervical Discectomy and Fusion (ACDF): Evaluation of Radiographic and Patient Outcomes

This is a prospective, non-randomized multi-center study to compare the use of Osteocel Plus in subjects who receive ACDF surgery at one or two levels. These subjects will present with degenerative conditions in the cervical spine that are amenable to surgical treatment and will be screened prior to study enrollment. Subjects will receive Osteocel Plus, without any other biologic product, during their ACDF operation. The ACDF procedure will be conducted with a radiolucent graft containment device such that progression of fusion can be adequately assessed via radiograph. Subjects will be followed for 24-months following surgery to determine the number of study subjects that are solidly fused at or before 24 months postoperatively, and to determine the mean time to fusion. This data will be compared to published and/or retrospective data for autograft, synthetic ceramics and Bone Morphogenetic Protein (BMP).

Read the detailed description

A total of 175 subjects will be selected for enrollment in this study from multiple centers. The subjects will have degenerative conditions in the cervical spine and will be undergoing ACDF surgery as treatment at one or two levels. The following eligibility criteria are designed to select subjects for whom protocol treatment is considered appropriate. All relevant medical and non-medical conditions should be taken into consideration when deciding whether this protocol is suitable for a particular subject.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To evaluate the fusion rates of Osteocel Plus in one or two level(s) for ACDF subjects.

    Measured: from pre-op to 24-month follow-up

Secondary outcomes (3)
  1. To evaluate the rate of complications for Osteocel Plus and compare to published and/or retrospective data for autograft or bone morphogenetic protein (BMP).

    Measured: from pre-op to 24-month follow-up

  2. To evaluate and compare radiographic outcome with respect to clinical outcome (function and pain).

    Measured: from pre-op to 24-month post-op

  3. To evaluate and compare each outcome with respect to surgical time and blood loss.

    Measured: from pre-op to 24-month follow-up

Questions about this trial

What is this clinical trial studying?

An observational study of Degenerative Disc Disease in Cervical Spine, run by NuVasive at 17 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 8 inclusion and 11 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 24 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 17 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?

To evaluate the fusion rates of Osteocel Plus in one or two level(s) for ACDF subjects. (time frame: from pre-op to 24-month follow-up). 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 24 Dec 2025; AzTrials last refreshed its copy on 7 Nov 2026.
