SI Joint Fusion
What it is
SI joint fusion joins the SI joint, where your spine meets your pelvis, so it moves less. Small implants are placed through a small cut. It may be an option when SI joint pain has not improved with other care.
Why it is done
- Chronic SI joint pain confirmed by exam and diagnostic injection
- Pain that has not improved after at least six months of conservative care
- Patients without conditions that make the procedure unsafe
What to expect
- Before: A test injection into the SI joint helps confirm the pain source. You may need imaging and a health check.
- During: You get anesthesia or sedation. The surgeon places small implants across the joint through a small cut. Many people go home the same day.
- After: You may need to limit weight on that side for a while. Physical therapy then helps you return to activity step by step.
Self-care tips
- Walk a little several times a day.
- Follow your limits on lifting, bending and twisting.
- Keep the cut clean and dry. Follow your wound care instructions.
- Take pain medicine only as directed. Do not smoke; it can slow healing.
When to call us
- Fever over 101°F or chills
- Redness, swelling or fluid draining from the cut
- Pain, swelling or redness in your calf
- New or worse numbness or weakness
Call 911 for chest pain, trouble breathing, or loss of bladder or bowel control.
