Brief Summary

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.

Conditions

Sacroiliac Joint Dysfunction

Keywords

sacroiliac joint fusion; SIJ Fusion; SI Joint; SIJ

Outcome Measures

Primary Outcomes (2)

• 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.

  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.

  6 months

Secondary Outcomes (1)

• SI Joint Pain Reduction

  24 Months

Interventions

SImmetry Sacroiliac Fusion System DEVICE

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.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

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

You may qualify if:

• Subjects must be indicated for the SImmetry device according to the approved SImmetry labeling
• Subject has two (2) 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 two (2) diagnostic SIJ injection at least one (1) resulting in a ≥50% decrease in pain in the joint(s) from the anesthetic portion of the injection
• The subject has VAS back pain score of ≥ 50 mm
• The subject is at least 18 years of age and skeletally mature
• The subject agrees and is able to comply with study requirements

You may not qualify if:

• 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 indicated for or awaiting other spine surgery
• The subject is pregnant or is planning on becoming pregnant in the next two years
• The subject has uncontrolled insulin dependent diabetes mellitus (Type 1 Diabetes)
• The subject has chemical dependency abuse problems as evidenced by a history of abusing drugs which is documented in their past medical history or is elicited from an interview
• The subject is receiving or seeking worker's compensation, disability remuneration, and/or involved in litigation related to low back or SIJ pain
• The subject has a history of significant emotional or psychosocial disturbance (untreated or uncontrolled anxiety attacks, obsessive/compulsive disorders, depression or schizophrenia) as documented in their past medical history or elicited by an interview
