THE FACE OF FUSION
ACDF | ALIF | LLIF | PLIF | TLIF
HEDRON® 3D printed titanium interbody spacers feature a biomimetic porous scaffold designed to promote bone formation onto and through the implant.
Osseointegration between an implant and surrounding bone may help achieve stability. HEDRON® integrates biomimetic architecture with characteristics of established interbody fusion devices.

Strength and Porosity
Unlike first generation 3D printed implants (grid and open architecture), HEDRON® strikes the ideal balance of strength and porosity through a sturdy frame and pore size distribution similar to trabecular bone.
Small pores (<300μm) are recommended to support initial surface adhesion2
Large pores (>300μm) have been shown to lead to direct osteogenesis3

In Vitro testing demonstrated that HEDRON® generated a greater expression of Vascular Endothelial Growth Factor (VEGF) and Osteocalcin, two biological indicators of bone formation when seeded with osteoblasts.4

Unlike PEEK and TAV, the porous architecture of HEDRON® allows for bone to grow through the spacer walls and incorporate into the fusion mass. In a pre-clinical ovine study, HEDRON® implants showed significantly more bone growth compared to PEEK and titanium implants at 6-weeks post-op.5
A pre-clinical sheep interbody study using HEDRON®, Titanium (Ti), and PEEK implants was performed to compare bone ingrowth and ongrowth.
