Two-Year Outcomes from a Randomized Controlled Trial of Minimally Invasive Sacroiliac Joint Fusion vs. Non-Surgical...

Area of Science:

• Orthopedics
• Spine Surgery
• Pain Management

Background:

• Sacroiliac joint (SIJ) dysfunction is a significant, often overlooked, cause of chronic low back pain.
• Effective treatment options for SIJ dysfunction remain an area of active research and clinical interest.

Purpose of the Study:

• To prospectively compare outcomes between surgical (minimally invasive SIJ fusion) and non-surgical management for chronic SIJ dysfunction.
• To evaluate pain reduction, disability improvement, and quality of life changes in both treatment groups over 24 months.

Main Methods:

• A prospective randomized controlled trial involving 148 subjects with SIJ dysfunction.
• Random assignment to minimally invasive SIJ fusion (SIJF) or non-surgical management (NSM).
• Assessment of SIJ pain (VAS), disability (ODI), and quality of life (EQ-5D, SF-36) at baseline and up to 24 months.

Main Results:

• Minimally invasive SIJF demonstrated significantly greater improvements in SIJ pain and disability compared to NSM at 24 months.
• A high percentage of SIJF patients achieved clinical improvement or substantial clinical benefit in pain and disability scores.
• Non-surgical management showed minimal improvement, with a substantial proportion of patients crossing over to surgical treatment.

Conclusions:

• Minimally invasive SIJF using triangular titanium implants is an effective treatment for chronic SIJ dysfunction, yielding superior and sustained improvements.
• SIJF offers significant advantages over non-surgical management in alleviating pain, reducing disability, and enhancing quality of life for patients with SIJ dysfunction.
