Patented Posterior-Oblique Access

The SacroFuse system from Sacrix™ is built around a posterior-oblique trajectory for sacroiliac joint fusion, enabling complete stabilization through a single percutaneous incision of less than 1.5 cm. This pathway avoids major muscle groups and vascular structures, reducing iatrogenic risk while maintaining direct access to the joint line.

Hybrid Screw-Cage Architecture

At the core of SacroFuse’s performance is its hybrid implant design. The device combines the compressive stability of a screw with the osteointegration surface of a cage, allowing it to:

• Self-drill and self-tap during insertion, eliminating the need for separate pilot drilling.

• Apply controlled compression across the SI joint for enhanced mechanical fixation.

• Maintain over 1 cc of graft chamber capacity, enabling biologically robust fusion without sacrificing structural integrity.

Two-Step Procedural Workflow

The SacroFuse platform is optimized for procedural efficiency:

1. Trajectory Preparation – implant threads cut and shape the channel while simultaneously harvesting autologous bone.

2. Implant Deployment – device is advanced to final position with integrated graft packing, minimizing steps and operative time.

This streamlined workflow reduces fluoroscopy time and supports reproducible results across varying facility settings.

Fixation Mechanics & Material Science

The implant’s thread geometry and surface profile are engineered for high pullout resistance in both cortical and cancellous bone. The combination of large surface area engagement and compression mechanics improves immediate postoperative stability, a critical factor for early fusion success.

Integrated Support for Clinical Deployment

From a technology integration standpoint, Sacrix™ pairs the SacroFuse system with:

• Surgeon training and certification programs for posterior-oblique technique.

• Detailed procedural documentation including technique guides and research data.

• Coding resources (ICD-10, CPT) to align technology adoption with operational and reimbursement processes.

Conclusion

Sacrix™ SacroFuse represents a deliberate engineering shift in SI joint fusion—merging precision implant design with a reproducible, minimally invasive access pathway. Its posterior-oblique approach, hybrid screw-cage architecture, and efficient workflow make it a platform built for both biomechanical performance and procedural scalability.
