Study summary

The objective of this study is to evaluate 6-to-12-month radiographic outcomes of patients with sacroiliac joint disruptions or degenerative sacroiliitis that have already undergone treatment with the CATAMARAN SI Joint Fusion System. In addition, retrospective and prospective clinical outcomes will be evaluated.

Read the detailed description

Patients with degenerative sacroiliitis or sacroiliac joint disruption who already had the CATAMARAN Fixation Device implanted between 6 and 12 months will be asked to return for follow-up visit to evaluate clinical outcomes and undergo a high resolution pelvic CT-Scan to assess fusion. Additionally, retrospective clinical outcomes will be collected from the medical records.

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. Radiographic Fusion

    The primary endpoint is the proportion of subjects that demonstrate radiographic fusion assessed by CT-Scan, as evaluated by an Independent Radiologist.

    Time frame: 6-12 month post CATAMARAN Fixation Device implantation

Secondary outcomes

  1. Device Status

    Radiographic assessment for device status: device placement, loosening, migration and/or breakage

    Time frame: 6-12 months post-op

  2. Surgical re-intervention for SI joint pain

    Proportion of patients requiring surgical re-intervention (removal, revision, reoperation, or supplemental fixation) for SI joint pain

    Time frame: 6-12 months post-op

  3. Neurologic worsening related to the sacral spine

    Proportion of patients experiencing neurologic worsening related to the sacral spine compared to baseline

    Time frame: 6-12 months post-op

  4. Serious device related adverse events

    Summary of all serious device related adverse events

    Time frame: 6-12 months post-op

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 Apr 21, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
