Low-impact stabilization designed for efficient care
Si-Logix supports a streamlined, two-implant approach to sacroiliac joint fusion using allograft implants placed under fluoroscopic guidance.
Engineered for procedural clarity
Three principles guide the system: a reproducible approach, a low-profile instrument footprint, and a sterile-ready workflow.
Posterior, Fluoroscopy-Guided
A reproducible approach designed for consistent, imaging-guided placement with two allograft implants.
Low-Profile Instrumentation
Streamlined instrument set designed for a small procedural footprint and efficient operating room setup.
Sterile-Ready Workflow
Pre-sterilized, single-use kit ships separately from allograft. No reprocessing required.

Two cylindrical allograft implants
Si-Logix uses two cylindrical allograft implants designed for a posterior, imaging-guided approach to the sacroiliac joint. This streamlined configuration is intended to support consistent placement and reproducible procedural workflow.
Pre-Sterilized Kit
Single-use instrumentation arrives ready to use. No reprocessing steps required.
Separate Shipping
Allograft implants and instrumentation ship in separate containers for streamlined logistics.
Consistent Workflow
Designed for reproducible fluoroscopy-guided placement with standardized procedural steps.
Built around a streamlined workflow
From a sterile-ready kit to reproducible placement, the system is designed to fit efficiently into your OR environment.
Pre-Op Prep
Sterile-ready, single-use instrumentation kit arrives pre-packaged and ready for immediate use.
Patient Positioning
Posterior approach supports standard fluoroscopic positioning for consistent access to the SI joint.
Guided Placement
Two cylindrical allograft implants placed under fluoroscopic guidance using a reproducible technique.
Streamlined Close
Low-profile instrumentation supports an efficient procedural footprint and straightforward closure.
