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.

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.
