Sacroiliac Joint Fusion

Sacroiliac Joint Fusion

For patients with severe SI joint instability or persistent pain that does not improve with conservative treatment, minimally invasive sacroiliac joint fusion may be considered.

This procedure stabilizes the joint and reduces abnormal movement that can cause ongoing pain.

Benefits of SI Joint Fusion

  • Stabilizes the sacroiliac joint
  • Reduces abnormal motion that causes pain
  • Provides long-term structural support
  • Performed through small incisions with minimal downtime

SI joint fusion is typically recommended only after conservative treatments such as injections and radiofrequency ablation have been exhausted.

Signs You May Have SI Joint Dysfunction


Sacroiliac joint pain can sometimes mimic other spine conditions, making proper diagnosis essential. Common symptoms include:

  • Pain in the lower back or buttocks
  • Discomfort when sitting for extended periods
  • Pain when standing up from a seated position
  • Radiating pain into the hips or thighs
  • Increased pain during walking or weight-bearing activities

At Nona Spine and Pain Institute, we perform a comprehensive diagnostic evaluation to determine whether your symptoms originate from the SI joint or another spinal structure.
