Subjects who are indicated for the SImmetry device and meet the inclusion/exclusion criteria will receive a SImmetry implant.
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.
- SI Joint Fusion [ Time Frame: 12 months ]Fusion of the SI joint at 12 and 24 months, defined as presence of a continuous segment of solid bridging bone that extends from the sacrum to the ilium. This will be assessed by an independent core laboratory
- 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.
- SI Joint Pain Reduction [ Time Frame: 12 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.
- Disability [ Time Frame: 6 months ]Functional ability as determined by the Oswestry Disability Index
- Quality of Life [ Time Frame: 6 months ]Quality of life assessment
