Patient Outcomes Evaluation of the EBI Vuelock™ Anterior Cervical Plate System

An observational study in Trauma, Tumor and Pseudarthrosis, sponsored by Zimmer Biomet. Completed at 4 sites in United States. Per ClinicalTrials.gov, last updated 2020-02-24.

Primary conditionPseudarthrosisRegistry: Wounds and InjuriesReclassifiedWhy we changed it
Registry
Wounds and Injuries — the first condition term the registry derived for this study.
ClinicalTrials.gg
Pseudarthrosis
Why
  1. The study's listed conditions name Pseudarthrosis, a narrower term within Wounds and Injuries.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study population

Subjects from multiple centers with disease of the cervical spine

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. The patient will undergo anterior cervical fusion with the VueLock™ Anterior Cervical Plate System for treatment of degenerative disc disease (as defined by neck pain of discogenic origin of the disc confirmed by patient history and radiographic studies), trauma, tumors, deformity (defined as kyphosis, lordosis, or scoliosis), pseudarthrosis, and/or failed previous fusion.
  2. The patient must be available for follow-up during the study.
  3. The patient must be skeletally mature (epiphyses closed).

Exclusion criteria

Exclusion Criteria:

  1. Patients with other pathology at the involved spinal level, e.g., osteomyelitis, Paget's disease, pathologic fracture, etc.
  2. Patients with a disease entity or condition that totally precludes the possibility of bony fusion such as known active cancer, etc.
  3. Pregnant or nursing females.
  4. Patients who in the opinion of the investigator would be psychologically unwilling or unable to understand or complete the protocol, especially those unwilling or unstable to participate in the follow-up.

The record gives a start of Aug 1998, a primary completion of Sep 2009 and a completion of Sep 2009. It does not say whether these dates are actual or estimated.

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 Feb 24, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
