Firebird SI
Fusion System

The Firebird™ SI Fusion System is a family of 3D printed titanium implants designed to compress and stabilize the sacroiliac joint during the fusion process. This novel device is designed with a porous mid-shaft region that allows bone to grow into its surface — creating a bond between the implant and the patient’s bone at the SI joint.

Product Highlights

  • Porous mid-shaft region that allows bone to grow into its surface
  • Axial fenestrations for bony through growth and post-procedure graft evaluation
  • Reverse cutting flutes and radial fenestrations for self-harvesting of autograft
  • Self-tapping threads for reduced procedural steps
  • Dual pitched threads and tapered proximal end for up to 3.75 mm of compression across the SI joint
  • Available in 11 mm and 12 mm diameter implants in lengths ranging from 25 mm to 70 mm to accommodate the variety of patient anatomies


The Firebird SI Fusion System is intended for fixation of sacroiliac joint disruptions, and intended for sacroiliac joint fusion for conditions including sacroiliac joint disruptions and degenerative sacroiliitis.


The Firebird SI Fusion System is contraindicated for use in patients with:

  • Open wounds, infection, presence of tumor, pregnancy, osteoporosis, certain metabolic disorders affecting osteogenesis, certain inflammatory / neuromuscular conditions, and certain neuromuscular deficits which would place an unusually heavy load on the device during the healing period.
  • The implant is made from Ti-6Al-4V ELI (medical-grade titanium alloy). The fixation implant is contraindicated in any individual with a known or suspected allergy, sensitivity or intolerance to metal.
