SI Joint Fusion

SI joint fusion stabilizes the sacroiliac joint to relieve chronic pain and improve mobility. Learn about the procedure and what to expect. 

SI Joint Fusion Overview

SI joint fusion is a minimally invasive procedure that stabilizes the sacroiliac (SI) joint, which connects the spine to the pelvis. This procedure is designed to relieve chronic lower back, buttock, and leg pain caused by SI joint dysfunction. By fusing the joint, movement is limited, reducing inflammation and restoring stability. 

What is SI Joint Fusion?

SI joint fusion is a surgical procedure that permanently stabilizes the sacroiliac joint to alleviate pain caused by dysfunction or instability.

  • Minimally invasive approach – Uses small incisions for quicker recovery. 
  • Bone graft or implants – Helps fuse the joint for long-term stability. 
  • Effective for chronic pain – Recommended for patients with SI joint dysfunction who do not respond to non-surgical treatments. 
     

Who should consider SI Joint Fusion?

SI joint fusion is recommended for patients with persistent sacroiliac joint pain that has not improved with conservative treatments.

  • Chronic lower back pain – Pain localized in the lower spine, pelvis, or buttocks. 
  • SI joint dysfunction – Instability or misalignment causing pain with movement. 
  • Trauma or injury – SI joint damage from falls, accidents, or previous surgery. 
  • Failed conservative treatments – non-surgical methods like injections and physical therapy have not provided relief. 
     

How effective is SI Joint Fusion?

SI joint fusion has been shown to provide lasting pain relief and improved function for patients suffering from sacroiliac joint dysfunction.

  • Significant pain reduction – Most patients report a decrease in lower back and pelvic pain. 
  • Improved stability – Fusion prevents excessive joint movement that causes inflammation. 
  • Minimally invasive benefits – Faster recovery compared to traditional open surgery. 
  • Long-term relief – Many patients experience lasting results with improved mobility. 

What happens during SI Joint Fusion?

SI joint fusion is a minimally invasive procedure performed under anesthesia.

  • Small incision – A small cut is made near the sacroiliac joint. 
  • Implant or bone graft placement – Stabilizes the joint and promotes fusion. 
  • Nerve decompression – Relieves pressure from inflamed nerves. 
  • Gradual recovery – Most patients resume normal activities within weeks.
