Minimally invasive SI joint fusion: 5 key notes on 40th publication

Spinal Tech

A new multicenter retrospective study with a prospective evaluation of SI-BONE’s iFuse system shows how minimally invasive sacroiliac joint surgery can impact the appropriately-selected patients.

The paper follows 107 patients from seven centers in the United States with a 3.7 average follow-up after minimally invasive SI joint fusion. The researchers found:


1. Average SI joint pain at baseline was 7.5, but at the 3.7 year follow-up the SI joint pain score showed a 4.8-point improvement to 2.6.


2. The average ODI score at follow-up was 28.2, similar to the two-year prospective clinical trial outcomes for SI joint fusion.


3. Only five patients reported revision surgery, identical to the results from the two-year study.


4. There are now 40 peer-reviewed publications supporting the positive clinical outcomes for minimally invasive SI joint fusion, two of which are randomized controlled trials. The device has FDA clearance.


5. The minimally invasive SI joint fusion is covered by several Medicare contractors across the United States.
