Deformity
Fixation
- Rigid titanium construction and triangular implant geometry provide immediate stabilization.
- Unique design provides interference fit between the implant and the surrounding bone (cortical and cancellous bone).
- 6X greater rotational resistance vs. screw.82
Fusion
- 3D printed implant with porous surface facilitates bone ongrowth.17
- Fenestrated structure allows through growth and accommodates bone graft.17
- Porous surface self harvests bone during insertion.17
Foundation
- Immobilization and stabilization of the sacroiliac joint (SIJ) provides a foundation for long constructs that includes spinopelvic fixation.
- 30% reduction in SI joint motion by adding iFuse Bedrock to sacral-alar iliac (S2AI) screws.114
More Levels. More Stress.
A 2009 paper published in Spine by Ivanov showed fusing the L5-S1 and L4-S1 increased the motion (stress) of the sacroiliac joint by 52% and 168%, respectively.112
Conversely, there is little increase in motion of the lumbar spine (2-4%)113 and little increase in hip stress (5%)114 after fusing the sacroiliac joint.

SI Joint ROM
S2A1 Bending Movement
- iFuse Bedrock stabilized the SI joint as measured by decreased ROM
- S2AI and S2AI with iFuse Bedrock decreased the bending moments on the S1 screw (reduced S1 screw stresses)
- iFuse Bedrock decreased the bending moments on the S2AI screw (reduced S2AI screw stresses)
