iFuse 3D™ in Trauma

Accelerated Fusion¹⁰⁴, Clinically Proven Outcomes

Minimally invasive surgical fusion of the sacroiliac (SI) joint

Features

FuSIon 3D™ porous titanium surface

Self-harvests bone during press-fit implantation and mimics cancellous bone for ongrowth and ingrowth.¹⁰⁹

Patented fenestrated design

Provides ample strength to withstand the heavy loads of the SI joint while allowing bone through growth.¹⁰⁹

Triangular design has 6X more rotational resistance than screws⁸²

Provides immediate stabilization of the SI joint.

Threaded base

Allows for easy implant adjustments.

The iFuse 3D™ Implant

Fix

Triangular implant geometry provides immediate stabilization.
Unique design provides press fit fixation between the implant and adjacent osseous walls.
31x greater rotational resistance vs. 7.3mm screw.⁸²

Fuse

3D printed implant with porous surface facilitates bone ongrowth.¹⁷
Fenestrated structure allows for bone through growth and accommodates bone graft.¹⁷
Porous surface self harvests bone during insertion.¹⁷

Fortify

Rigid titanium construction provides an implant that is 18x stronger than the worst-case physiologic load, thus fortifying the SI joint.⁸³
More than 5x fewer revisions after fusion with iFuse vs. iliosacral screws.⁸¹

The Role of SI Fusion in Pelvic Trauma

It is one of the most gratifying procedures that I actually perform in spine surgery. It's truly been a change for my practice, for the good.”

Case Studies

The iFuse Trauma Technique

Clinical Brief

Summary

Retrospective, multicenter review of 50 patients with high and low energy pelvic trauma treated with the iFuse Implant System^® in adjunct to traditional hardware fixation.

Average decrease in Visual Analog Scale (VAS) pain score from 8.9 at time of fracture to 1.9 at last follow-up.

On average, functional mobility was restored to pre-fracture status.
