Study summary

The objectives of this clinical observational study is to evaluate the safety and efficacy (performance) of the Neo Pedicle Screw System™ and the Neo Cage System™ interbody fusion device. To demonstrate non-inferiority of safety and function to an historical control from the published medical literature on competitive devices.

Study population

In total, approximately 150 patients will be recruited and enrolled to ensure that at least 132 patients are evaluable at 12 and 24 months. Patients are recruited consecutively, retrospectively as well as prospectively. The potential patients to be recruited have either already been implanted or are planned to be implanted with the Neo Pedicle Screw System (Arm 1) or Neo Cage System and Neo Pedicle Screw System (Arm 2).

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

  • Patient has undergone or is intended to undergo surgery with the Neo Pedicle Screw System™, standalone or in combination with the Neo Cage System™, for any of the approved indications as defined in the respective labelling
  • Patient has participated in or is willing to participate in the routine postoperative follow-up program
  • Patient is willing to provide written

Exclusion criteria

Exclusion criteria:

  • Patient is under the age of 18 or skeletally immature
  • Patient had or has a to surgery or to any of the implant systems used in the study, as defined in the respective labelling
Terms in these criteria, in plain language(2)

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.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

What researchers measure

Primary outcomes

  1. Change in patient´s function from baseline to 12 months

    Clinical outcome in function as measured by the 100 point Oswestry Disability Index (ODI). Zero is equated with no disability and 100 is the maximum disability possible.

    Time frame: 12 months

  2. The rate of cage migration in cage-plus-screw systems.

    Defined as posterior movement of the cage past the posterior wall of the vertebral body.

    Time frame: 12 months and 24 months post operatively

  3. The rate of pedicle screw loosening in screw only and cage-plus-screw systems.

    A radiolucent zone, \>1mm, surrounding the pedicle screw seen in radiograhs

    Time frame: 12 months and 24 months post operatively

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

Ran from Oct 2019 to primary completion in Jan 2025, 63 months.

Of 80 observational studies under Intervertebral Disc Degeneration, half reached primary completion within 61 months of starting (the median), counting those still running; a quarter within 45 and three quarters within 84. This study's 63 months is close to 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 Jun 13, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
