Study summary

The primary objective of this study is to evaluate the safety and performance of anterior cervical spine surgery using the NuVasive anterior cervical plate (ACP) System as measured by reported complications, radiographic outcomes, and patient-reported outcomes (PROs).

Read the detailed description

This study is a prospective, uncontrolled, multicenter study to evaluate the safety and performance of the NuVasive ACP System in patients who undergo anterior cervical spine surgery. Consecutive patients at a given site who meet eligibility requirements will be asked to consent to participate in the study. These patients will present with pathologic conditions in the cervical spine that are amenable to surgical treatment and will be screened prior to study enrollment. Once enrolled in the study, subjects will undergo anterior cervical spine surgery using the NuVasive ACP System based on the surgeon's standard of care. At least 75 subjects will be enrolled and will be followed for 24 months after the surgery.

Study population

The Enrolled Population will include all subjects who meet the criteria for enrollment, specifically, those subjects who:

  • Satisfied the inclusion and exclusion criteria,
  • Signed the informed consent, and
  • Underwent the surgical procedure, as defined in this protocol. Subjects not meeting any of these criteria will not be considered enrolled in the study, and therefore not included in any study population or analysis.

The Evaluable Populations will include all subjects who:

  • Were included in the Enrolled Populations,
  • Completed the study, and
  • Had no major protocol deviations. If there are no major protocol deviations and all subjects complete the study, then an Evaluable Population will not be used.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Patients who are ≥18 years of age at the time of consent
  2. Have planned anterior cervical (C2 to C7) spine surgery using the NuVasive ACP System in conjunction with a NuVasive interbody implant or vertebral body replacement device (VBR), or a structural bone allograft spacer, for treatment of any of the following conditions:

    1. degenerative disc disease, as defined by neck pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies
    2. trauma (including fractures)
    3. tumors involving the cervical spine
    4. cervical spinal deformity (kyphosis, lordosis, or scoliosis)
    5. failed previous cervical fusion(s) (e.g., pseudoarthrosis)
    6. cervical spondylolisthesis
    7. cervical spinal stenosis
  3. Able to undergo surgery based on physical exam, medical history, and surgeon judgment
  4. Understands the conditions of enrollment and is willing to sign an form to participate in the study

Exclusion criteria

Exclusion Criteria:

  1. Procedures performed with interbody implants with integrated vertebral body screw(s)
  2. Patient is involved in active litigation relating to the spine (worker's compensation claim is allowed if it is not contested)
  3. Use of bone growth stimulators postoperatively
  4. Active smoking within 6 weeks of surgery
  5. Patient has known sensitivity to materials implanted
  6. Systemic or local infection (latent or active) or signs of local inflammation
  7. Patient has inadequate bone stock or quality, or a physical or medical condition that would prohibit beneficial surgical outcome based on surgeon judgment
  8. Pregnant, or plans to become pregnant
  9. Patient is a prisoner
  10. Patient is participating in another clinical study that would confound study data
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Complications NuVasive ACP System

    Rate of complications (i.e., safety) attributable to use of the NuVasive ACP System

    Time frame: 24 months

  2. Radiographic Success

    Proportion of subjects with radiographic success at: 1. Latest time point available for patients undergoing surgery to treat advanced stage tumors 2. 24 months postoperative for subjects undergoing surgery to treat instabilities, traumatic spinal fractures, failed previous fusions, or degenerative disease

    Time frame: 24 months

Secondary outcomes

  1. Clinical Outcome Success

    Percentage of subjects meeting minimal clinically important difference (MCID) and/or substantial clinical benefit (SCB) thresholds for each PRO: neck and arm pain (measured by visual analog scale (VAS)), disability (measured by neck disability index (NDI)), and overall physical and mental health (measured by PROMIS-10)

    Time frame: 24 months

  2. Rate of Postoperative Dysphagia

    Rate of postoperative dysphagia as measured by the Eating Assessment Tool (EAT-10)

    Time frame: 24 months

  3. Rate of complications attributable to the use of NuVasive instruments, implants, or technologies

    Rate of complications attributable to the use of NuVasive instruments, implants, or technologies

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started May 2022 (actual). Primary completion is estimated for Sep 2026, 52 months after the start.

Of 18 observational studies under Spondylosis, half reached primary completion within 41 months of starting (the median), counting those still running; a quarter within 28 and three quarters within 74. This study's planned 52 months is above that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 22, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
