The sacroiliac (SI) joint fusion market has emerged as one of the most dynamic segments in spine surgery, fueled by increasing recognition of SI joint dysfunction, better diagnostic protocols, and the expansion of minimally invasive procedural options.

According to Grand View Research, the global SI joint fusion market was valued at $293.8 million in 2023 and is projected to grow at a CAGR of 19.3% through 2030, reaching well over $800 million by the end of the decade.

What’s Driving the Surge?

1. Underdiagnosis Is Being Reversed
   Studies now show SI joint dysfunction accounts for 15–30% of chronic low back pain, yet historically only a fraction of these patients were properly diagnosed or treated. Newer physical exam protocols and diagnostic injections are improving case identification.

2. Minimally Invasive Techniques Are Redefining Outcomes
   Devices like intra-articular screws and triangular implants now allow SI fusion through 1–2 cm incisions, with <1-hour OR time and reduced post-op morbidity. These advances make it a viable option in ASC settings.

3. Payer Acceptance Has Increased
   While previously considered investigational, Medicare and most commercial payers now cover MIS SI joint fusion for properly indicated patients—boosting procedure volumes.
