Deep Dive:
The Posterior Oblique Technique for SI Joint Fusion

Featuring SACRIX’s Revolutionary Approach 

With Sacrix, a portfolio company of KIC Ventures, innovation isn’t about reinventing the wheel, it’s about engineering smarter solutions to old problems. One such problem? Sacroiliac (SI) joint dysfunction, a major but often under-treated cause of lower back pain.

​

In our featured video, Cutting Edge SACRIX SI Joint Transfixation: Posterior Oblique Technique by Harvard Spine Surgeon - Dr. Kingsley Chin, we showcase an advanced, minimally invasive technique that redefines what’s possible in SI joint surgery. 

​

We’re using this opportunity to share with our audience, both physicians and curious learners, about the surgical process, while calling out the salient features that make this method a true differentiator in spine care. 

 

 

Key Highlights of the Technique-

​​

​

1. Posterior Oblique Trajectory 

Unlike traditional approaches, this path avoids gluteal muscles and blood vessels, ensuring a cleaner, safer route to the joint. 

​​

​

2. 1.5 cm-2 cm Bloodless Incision â€‹

Yes, you read that right. 

The procedure is executed through a tiny, less than 1-inch incision, minimizing tissue trauma and maximizing patient comfort. 

​​​

​

3. Sequential Implantation â€‹

Each implant is placed 20–25 mm inferior to the previous one, mimicking its trajectory to ensure consistent and secure fixation. 

​

​

4. Performed in Minutes â€‹

This procedure can be completed in under 10 minutes, and it’s often done in outpatient settings—patients walk in and walk out the same day. 

​

​​

Engineered Strength â€‹

The Sacrofuse™ implant has shown a 400% increase in pull-out strength when compared to legacy competitors. That’s not just innovation, it’s impact. 

​

​

Why This Matters â€‹

The Sacrix technique offers: 

​

  •  Reduced OR time 

  •  Smaller incisions 

  •  Less bleeding and muscle disruption 

  •  Greater implant security 

  •  Faster patient recovery 

​​

​

All with the ease of execution that empowers trained spine surgeons and interventionalists to deliver results that matter.
