Summary
Minimally invasive sacroiliac (SI) joint fusion significantly reduced pain and disability in patients with SI joint dysfunction. The procedure improved quality of life, with high patient satisfaction reported at 6 and 12 months post-surgery.
Area of Science:
- Orthopedic Surgery
- Spinal Fusion Techniques
- Pain Management
Background:
- Sacroiliac (SI) joint dysfunction is a common cause of low back pain.
- Minimally invasive surgical techniques are increasingly explored for SI joint fusion.
Purpose of the Study:
- To evaluate the efficacy of minimally invasive SI joint fusion using triangular titanium implants.
- To assess improvements in pain, disability, and quality of life.
Main Methods:
- Prospective, multicenter, single-arm clinical trial with 172 subjects.
- Minimally invasive SI joint fusion performed between August 2012 and January 2014.
- Standardized assessments including VAS pain, ODI, SF-36, and EuroQOL-5D preoperatively and up to 12 months postoperatively.
Main Results:
- Significant reduction in mean SI joint pain (79.8 to 30.0) and Oswestry Disability Index (55.2 to 32.5) at 6 months.
- Improvement in SF-36 physical component summary scores (31.7 to 40.2) at 6 months.
- High patient satisfaction rates: 93% at 6 months and 87% at 12 months were satisfied, with 92% and 91% willing to undergo the procedure again, respectively.
Conclusions:
- Minimally invasive SI joint fusion with triangular titanium implants is effective for treating SI joint dysfunction.
- The procedure leads to significant improvements in pain, functional disability, and overall quality of life.
- High patient satisfaction and willingness to repeat the procedure indicate positive clinical outcomes.
