SAIF: Sacroiliac Fusion Study Using the Zyga SImmetry Sacroiliac Joint Fusion System

The purpose of the SAIF study is to evaluate the SImmetry Sacroiliac Joint Fusion System for fusion and pain reduction of the SI joint.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a prospective, non-randomized, single center study to collect data on fusion and pain reduction following implantation of the SImmetry device. Up to 15 total subjects will be implanted and followed for 24 months. Data will be collected pre-operatively, at implant, discharge, and at specified follow-up time points (6 weeks, 3 months, 6 months, 12 months, 24 months.)

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Actual)

Enrollment

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patients will be recruited from the Investigator's standard patient population diagnosed with SIJ pain and representing candidates' for SIJ fusion.

Description

Inclusion Criteria:

  • Subjects must be indicated for the SImmetry device according to the approved SImmetry labeling
  • Subject has three (3) positive (experiences pain) Provocative Tests for SIJ pain; for example, Compression, Thigh Thrust, FABER, Distraction or Gaenslen's
  • Subject has documentation of failed, non-operative management of SIJ pain for ≥ 6 months prior to surgery; for example, use of medications, braces, SI belts, orthotics, physical therapy or manual manipulation
  • The subject has one (1) positive diagnostic SIJ injection, resulting in a ≥50% decrease in pain from the anesthetic portion of the injection
  • The subject has VAS back pain score of ≥ 60 mm
  • The subject has an ODI ≥ 40%
  • The subject is at least 18 years of age and skeletally mature
  • The subject agrees and is able to comply with study requirements

Exclusion Criteria:

  • Subjects contraindicated per the cleared labeling will be excluded from participation in the study
  • The subject has pelvic soft tissue or bony tumors
  • The subject has had any trauma causing fracture of the sacrum or iliac bones or has had spinal trauma leading to a neurological deficit
  • The subject has a history of a central nervous system (CNS) disorder(s)
  • The subject is pregnant or is planning on becoming pregnant in the next two years
  • The subject has chemical dependency problems as evidenced by a history of drug abuse which is documented in their past medical history or is elicited from an interview
  • The subject has a history of significant emotional or psychosocial disturbance (anxiety attacks, obsessive/compulsive disorders, depression or schizophrenia) as documented in their past medical history or elicited by an interview

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
SImmetry Implant
Subjects who are indicated for the SImmetry Device according to the approved product labeling and inclusion/exclusion criteria will receive a SImmetry implant.
Device: SImmetry Implant

The SImmetry system is commercially available. The implanted devices consist of a range of thread-tapping cannulated implants designed to transfix the sacrum and ilim, 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 the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
SI Joint Fusion
Time Frame: 12 months
Confirmed fusion of the SI joint at 12 and 24 months, defined as as presence of a continuous segment of solid bridging bone that extends from the sacrum to the ilium.
12 months
SI Joint Pain Reduction
Time Frame: 6 months
SI joint pain reduction evaluated by use of Visual Analogue Scale (VAS) for back pain for comparison of baseline to 6 months.
6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
SI Joint Pain Reduction
Time Frame: 12 and 24 months
SI joint pain reduction evaluated by use of Visual Analogue Scale (VAS) for back pain for comparison of baseline to all follow-up visits.
12 and 24 months

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
February 1, 2014

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
