About this study
The purpose of the SI Joint Fusion and Decortication Using the SImmetry System study is to evaluate the SImmetry Sacroiliac Joint Fusion System for fusion of the SI joint and relief of SI joint pain symptoms.
Read the detailed description
This is a prospective, non-randomized post market study designed to collect data on SI joint fusion and subject back pain following implant of the SImmetry device. The study will be conducted at a single site and 25 subjects will be implanted and followed through 24 months. Data will be collected pre-operatively, implant, and at specified follow-up time points through 24 months.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
SImmetry Sacroiliac Fusion SystemDevice
SImmetry
The SImmetry device is commercially available. The implanted devices consist of a range of threaded, self-tapping, cannulated implants designed to transfix the sacrum and ilium, providing stability for intra-articular fusion.
The SImmetry Surgical Instruments include standard manual surgical instruments used to access and prepare the sacroiliac joint space for intra-articular fusion.
What is being measured
The primary outcome is the main question the study is designed to answer.
SI Joint Fusion
Number of participants with radiographic evidence of fusion of the SI joint, defined as presence of a continuous segment of solid bridging bone that extends from the sacrum to the ilium.
Measured: 24 months
SI Joint Pain Reduction
SI joint pain reduction evaluated by use of Visual Analogue Scale (VAS) for back pain for comparison of baseline to 6 months.
Measured: 6 months
Secondary outcomes (1)
SI Joint Pain Reduction
SI joint pain reduction evaluated by use of Visual Analogue Scale (VAS) for back pain for comparison of baseline to all follow-up visits.
Measured: 24 Months

The record says: stopped early, as of the sponsor's last update on 22 Dec 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was stopped early (reason given: No additional enrollment). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
SI Joint Fusion (time frame: 24 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Dec 2017.
