Study summary

The purpose of this retrospective clinical evaluation is to compare VEO® single or multilevel results to XLIF® single or multilevel results relative to the safety endpoints. This study will collect retrospective data on subjects who were treated with VEO® and XLIF® at least 3 months prior to the initiation of this study. Given that fusion generally takes at least 6 months to determine, the aim of this study is not to determine fusion but to consider the short-term (out to 6 months) reported adverse events between the two cohorts.

Devices used in both systems are cleared for use and conform to US regulatory requirements. The study employs these procedures and devices for uses that are consistent with their 510(k), legally cleared, labeling.

Study population

Approximately 40 subjects will be enrolled across the participating sites; 20 subjects who have been treated with the VEO® lateral system and 20 who have been treated with the XLIF® system. Consecutive subjects at the participating sites that meet all of the inclusion criteria and none of the exclusion criteria will be eligible for study participation until the enrollment target is reached.

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

  • Adult 18 years of age or older;
  • Male or female VEO® subjects that had previously received the single or two level LLIF procedure using the VEO® or XLIF® systems as an adjunct to fusion at L2-S1 to treat degenerative disc disease (DDD) at the treated level;
  • Subject that was treated no less than 3 months prior to this evaluation with the LLIF procedure using the VEO® or XLIF® system by the participating surgeons.

Exclusion criteria

Exclusion Criteria:

  • Subject who did not receive LLIF procedure using the VEO® or XLIF® system for fusion of L2-S1;
  • Subjects with less than 3 months of follow-up data.

What researchers measure

Primary outcomes

  1. Safety: Number of Participants Without Major Device-related Adverse Events and/or Failures

    Incidence of major device-related adverse events and/or failures, defined as those requiring revision surgery or a secondary operation, or events resulting in permanent disability or death.

    Time frame: Observed for up to 6 months post-surgery

Secondary outcomes

  1. Safety

    Incidence of short term peri-operative adverse events (out to 6 months post-implant) including thigh pain, numbness, paresthesia and transient leg weakness.

    Time frame: Observed for up to 6 months post-surgery

Baseline characteristics

Given the nature of this retrospective evaluation, the sample size was not statistically derived but was instead intended to be representative of the body of evidence that exist for real world usage of the VEO® device.

Not marked actual or estimatedDates not marked actual or estimated

The record gives a start of Jun 2013, a primary completion of Mar 2014 and a completion of Mar 2014. It does not say whether these dates are actual or estimated.

Results were first posted in Aug 2014, 5 months after primary completion.

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 Aug 12, 2014, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
