The iFuse-3DTM Implant offers a new dimension in SI joint fusion.

Minimally invasive surgical fusion of the sacroiliac (SI) joint using machined solid triangular titanium plasma spray (TPS) coated implants has demonstrated positive clinical outcomes in SI joint pain patients. 

The iFuse-3D Implant is created with the latest proprietary 3D printing technology. The surface mimics native cancellous bone and uses self-harvesting technology.

The iFuse-3D Implant combines the patented triangular shape of the iFuse ImplantTM with a proprietary 3D-printed trabecular surface and unique patented fenestrated design, which has demonstrated substantial bony ongrowth and ingrowth through growth and intra-articular fusion.

  • Self-Harvesting Technology: iFuse-3D captures bone during implantation that may be deposited into the implant.1
  • Fenestrated structure may be pre-packed with autograft or allograft, 1-3cc depending on implant size.
  • Triangular design has 31X more rotational resistance than screws*5
  • 3D-printed surface specifically designed to mimic trabecular bone architecture

Additive manufactured implants provide a highly interconnected surface that has comparatively greater surface area for bony integration.

The iFuse Implant System® is intended for sacroiliac fusion for conditions including sacroiliac joint dysfunction that is a direct result of sacroiliac joint disruption and degenerative sacroiliitis. This includes conditions whose symptoms began during pregnancy or in the peripartum period and have persisted postpartum for more than 6 months.
