Study of Bone Growth in the Sacroiliac Joint After Minimally Invasive Surgery With Titanium Implants

You may not qualify if:

• Patient has bilateral SI joint symptoms with VAS pain scores ³50 on both sides and patient refuses to undergo bilateral treatment according to the study protocol.
• Patient is currently pregnant, actively trying to become pregnant or is planning to become pregnant in the next year.
• Severe back or hip pain due to other causes, such as lumbar disc degeneration, lumbar disc herniation, lumbar spondylolisthesis, lumbar spinal stenosis, lumbar facet degeneration, lumbar vertebral body fracture, piriformis syndrome, femoral acetabular impingement, labral tear or hip osteoarthritis. Patients with low back pain VAS ratings more than 50 should be carefully considered; they should not participate if the investigator believes these non-SIJ conditions would impair improvement from SIJ treatment.
• SI joint dysfunction due to an alternative explanation such as:
• Inflammatory sacroiliitis (e.g., ankylosing spondylitis or other HLA-associated spondyloarthropathy)
• Tumor
• Infection
• Acute or unstable fracture.
• History of recent (\<1 year) major non-pregnancy-related trauma to pelvis.
• Surgeon believes patient body habitus prevents surgery.
• Previously diagnosed osteoporosis (defined as prior T-score \<-2.5 or history of osteoporotic fracture) or prior/current use of drug therapy for osteoporosis.
• Prior fracture of any bone related to cancer/tumor (i.e., pathologic fracture).
• Prior diagnosis of tumor in sacrum or ilium.
• Unstable fracture of sacrum and or ilium involving the targeted SIJ.
• Osteomalacia or other metabolic bone disease.
